Retraction

For weeks I have been having problems with my XYZ Da Vinci Jr. 1.0w 3D printer. Some prints work just fine, while other fail. Even worse, some prints which work fine if I try to print a single figurine then fail if I try to print multiple copies at the same time. It was driving me crazy, until with a lot of testing and observing I finally found out what the problem is: Retraction.

So what is retraction in 3D printing? Imagine printing a model of the Eiffel Tower. There is a lot of empty space in such a model. Because the print is done layer by layer, from the bottom up, the print head has to print a small thickness where a girder is, then move without printing to the next girder. In order to prevent PLA from coming out of the print head and causing strings to appear between the girders, the stepper motor is pulling the filament back a little bit before moving. That pulling back is called retraction.

Now what is happening with my printer, and I am not 100% sure how or why, is that the stepper motor is more efficient during retraction than during moving the filament forward. It basically retracts too much, and then after the movement pushes forward the filament by too little. So if I print a piece with lots of empty spaces and lots of retraction happening, while the solid sections are relatively thin, I end up retracting more and more, until the end of the filament has completely left the hot part of the extruder head. While the print head is still moving, there is no more plastic coming out of the nozzle at all, and the print fails.

Now there is a lot of 3D printing software with millions of settings where you can change the setting for retraction. Unfortunately the XYZ Printers don’t work with any of those 3D printing programs. They only work with their proprietary XYZWare. Which is deliberately simplified to make “plug and play” printing for the average customer possible. Somewhere in the depths of the code there must be a retraction setting (you can observe the filament moving backwards), but there is no way to access or change that setting. And I don’t want to “jailbreak” my 3D printer with some modified firmware, because that has the potential to completely break it.

Right now my solution is simply to avoid printing models with too much empty space in them. That means printing miniatures one by one instead of in batches, which would be more practical for prints during the night. But the long-term solution will be buying a better 3D printer which isn’t so limited with what software I can use, and what settings I can change. Right now I am thinking of still waiting a bit with that, as I haven’t found the printer of my dreams yet. One important feature for me is being able to print via WiFi, and surprisingly few printers have that. I want a pre-assembled 3D printer with a sturdy frame, not a wobbly self-assembly kit. But of course I don’t want to spend a fortune on it either. My $500 printer is maybe not high enough quality, but I wouldn’t want to spend more than $2,000 even on a good printer. As the market is developing, I might find the printer I want next year.

Life is Pay2Win

I was listening to some well-known YouTubers complaining about lootboxes in new games like Star Wars Battlefront II or Shadow of War and pointing out in painstaking detail how getting this or that bonus unbalances the game in favor of people who buy lootboxes. However they appeared to be totally okay with other people getting the exactly same bonuses by grinding the game for many, many hours. And that annoyed me. Wouldn’t we be much better off if our multiplayer PvP games would be perfectly balanced and the outcome only determined by skill? If you can get bonuses that make you much stronger than another player, why would it matter whether you got them by playing the game for endless hours or by using your credit card? It appeared to me as if some hardcore gamers are quite okay with a game being unfair, as long as that unfairness favors them and their kind.

The only advantage playing a game for longer should be the skill you acquire by practice. Any other bonus you get from grinding is in fact a historical and economical anomaly. The practice will certainly disappear over the coming decade, because it simply isn’t in the interest of game companies to keep doing so. Companies don’t *want* players that use a lot of their bandwidth but give them no money. The only free players they want is those that they are still trying to persuade to cough up some cash.

Fact is that life itself is Pay2Win. In a consumer society, the more money you have, the more luxury you can afford. The whole “American Dream” idea is built around the concept that money is the yardstick for success in life, and that by working hard on pursuits that actually earn you money or improve your chances to earn money later, you are leading a better life. Even the people who would like wealth to be redistributed don’t complain about the fact that more money buys you a better car or the best seats in the theater. So why exactly should video games be exempt from that?

Games went from being fair and balanced to being unfair based on time spent. Now they are moving from there to being unfair based on money spent. People complaining about that on YouTube or various internet forums isn’t going to change that, because millions of people will buy those new games with their new unfairness. Because for millions of people the new unfairness is actually an improvement over the old unfairness. Gaming has become a mass market for the general population, and in the general population there are more people who can afford to spend $100 than there are people who can afford to spend 100 hours. Calling for that to be rolled back to the previous state of unfairness doesn’t even have the benefit of being moral, the moral situation would be games that don’t give you any advantages from neither time nor money.

Republican Senators Are Making Out Like Bandits with Special Real-Estate Tax Break

The GOP isn’t even masking its greed and corruption.

When the U.S. Senate takes up the final tax bill this week, more than a quarter of all GOP senators will be voting on a bill that includes a special provision that could give them a new tax cut through their real estate shell companies, according to federal records reviewed by International Business Times. The provision…

Is Trump an ‘Aspiring Despot’ or a ‘Bumbling Showman’? Why Not Both?

Author Brian Klaas warns the damage of Trump’s presidency will last a generation.

The presidency of Donald Trump has forced the American people to confront questions most of us had never before considered possible. What happens when a president has no respect for the Constitution and the country’s democratic institutions and traditions? When a president and his allies consider themselves above the law, what is to be done? If a president creates his own version of reality by behaving like a political cult leader, what forms of resistance are effective — or even possible? Is the president of the United States a fascist and demagogue who may be under the influence of the country’s enemies?

Too many Americans believed their country to be exceptional and unique. This blinded them to the threat to democracy embodied by Donald Trump — as well as other members of the extreme right-wing — until it was too late to stop him from stealing control. Moreover, the rise of Trump’s authoritarian movement (dishonestly operating under the mask of “populism”) has both empowered and revealed the tens of millions of Americans who have authoritarian or fascist leanings. The threat to American democracy is deep; it will take a long time to purge this civic sickness and political disease from the body politic.

In an effort to understand the true dimensions of Trump’s rise to power as a direct threat to American democracy, I recently spoke with Brian Klaas. He is a fellow in Comparative Politics at the London School of Economics. In addition to writing columns and essays that have appeared in the Washington Post, the New York Times, the Guardian, Foreign Affairs and numerous other publications, Klaas is the author of several books. His latest, published in November, is “The Despot’s Apprentice: Donald Trump’s Attack on Democracy.”

In our conversation, Klass explained his view that Trump is an aspiring despot whose behavior mimics other authoritarians both past and present, the role of Fox News and other elements of the right-wing media in maintaining and expanding Trump’s malignant reality and power, and the decline of the country’s prestige and influence abroad because of Trump’s regime.

This conversation has been edited for clarity and length.

How was Donald Trump able to win the White House?

I think that there are people who have been legitimately disaffected by stagnant wages for 30 years and growing income inequality. That is part of the story. But that is not the main story, given the backlash against immigration as well as Obama’s presidency and what that tells us about race relations. We also cannot overlook the fact that Trump’s voters have a median household income of about $72,000 a year.

We also have a third and often not-spoken-about trend where there simply are lots of authoritarian voters in every Western country. Effectively these are people who do not care about democratic processes or procedures; they don’t care about democratic values; they care about winning and they care about the government doing for them.

What previously existed was a sort of unspoken agreement that elites did not encourage these people. What Trump has done that will have lasting ramifications for the United States is that he has broken that dam and brought fringe elements into the mainstream — and there are now elites who will actually cater to them. But I fear it’s going to be many years, if not decades, before the proverbial Trump genie can be put in the back in the bottle and democracy can be restored to its full and proper functioning.

Why did the mainstream news media normalize Trump? What explains the allure of the narrative that Trump’s election was somehow about “economic anxiety” as opposed to white racism and racial backlash?

Because it is a nice story that many of us would like to believe. White racism is central to the story of the rise of Trumpism, and for the media to tell the story about America that basically says, “This president was elected because we have racial problems,” is much harder for people to square with the country’s mythology. I also think many journalists and other observers have very little experience with authoritarianism. I think minorities also saw this coming and were much more aware of it and much more prescient in seeing how damaging Trumpism could be than white people.

Is Trump a fascist? Why do you think so many in the mainstream media and America’s political class are afraid to describe him using that language, or at aminimumto label him an authoritarian?

He is an aspiring despot. That distinction is important because I have studied fully authoritarian societies where there are no checks and balances, no free media, no different branches of government, and it is far worse than the United States. But in terms of tactics, there is in immense amount of evidence to support the fact that Trump is behaving like an authoritarian and that he is mainstreaming fascism. Like other despots throughout history, Trump scapegoats minorities and demonizes politically unpopular groups. Trump is racist. He uses his own racism in the service of a divide-and-rule strategy, which is one way that unpopular leaders and dictators maintain power. If you aren’t delivering for the people and you’re not doing what you said you were going to do, then you need to blame somebody else. Trump has a lot of people to blame.

Others who want to deny that Trump is a fascist or authoritarian will object that he is too bumbling and incompetent for such strong labels to apply.

I completely disagree. You do not have to be effective to be destructive. Most despots are bumbling. Around the world we have seen examples of how they are often comical idiots and egotistical head cases. Despots are not necessarily the smartest people.

Trump is extremely destructive. The analogy I use is the idea that democracy is like a sand castle. It takes a long time to build and much longer to perfect. Trump is just washing it away. He is a wave and the castle is not going to be knocked down in one single tide. But the castle, and our democracy, gets eroded steadily over time. That is where we are now. How does a democracy function when a third of its people are cheering authoritarian tactics, embracing them, pushing for more candidates to mimic them, and fundamentally believe a huge number of things that are false? Because if you think about what democracy is, at its core it requires a shared reality to create consent of the governed.

The long-term corrosion of democracy that Trump is inviting is not going to end when he leaves office. It is going to be a persistent problem where he has opened up the possibility for a much more insidious and effective successor.

Moreover, I always thought that a Trump-like figure had the potential to break down the barriers between democracy and authoritarianism in America. The dazzling showmanship is essential. So if you imagine a genuinely scary authoritarian, a Mussolini in America type, we would actually stop that person very quickly. By comparison, Trump has this distracting quality because he’s a bumbling showman who seems harmless to some people because of those traits. This has created a creeping authoritarianism where the envelope is being pushed farther all the time.

Another important aspect of how Trumpism and his petit-fascist movement have taken hold is that the Republican Party is largely in agreement with his agenda. Political polarization and gerrymandering have made Republicans largely immune from accountability by the American people.

Polarization is absolutely essential as a precursor to authoritarianism because you need to have political tribalism. Republicans are afraid of their base. They are not afraid of a Democrat beating them. This is partly because of demographic clustering, but it’s also largely due to gerrymandering. And gerrymandering intensifies all of the incentives to be extreme. Consequently, if a Republican does not march in lockstep with Trump, he or she may face a primary challenger. The alternative is winning an easy election against a Democrat. On top of that you have Fox News and a broader right-wing echo chamber that are de facto outlets for Trump, akin to some type of state-sponsored media in an authoritarian or dictatorial regime.

Is there a magic number where a certain percentage of the population has to support an authoritarian for that democracy to fully fail?

I do not believe that there is necessarily a specific number. What is ultimately most important is the longevity of the person in power and how much of a rebuke they get from the public.

Therefore, one of the few positive scenarios I have for looking into the future is what I label as “Trump vaccine.” This is basically the idea that because Trump embodies bumbling recklessness and impulsivity, he is a weakened form of authoritarian populist. This means there is a plausible scenario where a sufficient backlash effectively neutralizes him, yet he also exposes all the weaknesses in our democratic system. Ultimately, Trump acts like a vaccine who strengthens the immune system of American democracy.

But I do not think that is going to happen because America is experiencing the slow decline of its democracy. You see this all the time in places like Turkey or Russia or Belarus, where a quasi-democratic system is getting hollowed out. This pattern of testing the waters is very familiar to me — it’s exactly what [Recep Tayyip] Erdogan has done in Turkey.  He just pushes the envelope every day. And the less backlash there is, the more he does it.

How much of Trump’s strategy is intentional? Is he just a useful idiot for the Republican Party and other elements of the radical right-wing? 

Regarding consequences, the distinction is less important. But in terms of intentionality, it is important to understand why someone does what they do. Some of the worst authoritarians in history are not necessarily strategic thinkers.

I don’t know whether Trump has some sort of grand strategy. Frankly, I would be extremely surprised if he did because virtually nothing Trump does fits into a strategic framework. Many of his goals are being passed and advanced in spite of him, as opposed to because of him. Authoritarians don’t need to have a grand strategy. Because they are narcissists, they are often making it up as they go along.

What roledoesthe Russia collusion scandal and Trump’s response to Robert Mueller’s investigation play in your analysis of America’s descent into authoritarianism? 

Any democracy needs to have a functioning rule of law that is separate from politics. In authoritarian states the rule of law is a weapon that the leader uses against his enemies and to reward his friends. The people who are guilty are whoever the authoritarian leader says are guilty. We are sliding down that path before our eyes every day. Trump has threatened Hillary Clinton with jail. He has pardoned a political ally, [former Phoenix sheriff] Joe Arpaio. This is a clear signal from Trump to anybody who is involved in the Russia investigation that he will reward his allies with pardons, and if they turn, that avenue will get cut off. This is very common under authoritarian rule, where justice is dealt out based on alliances and there are investigations of opponents.

I think the other aspect is obviously related to the notion that the president is above the law. For example, the question is absolutely settled that Donald Trump’s campaign at least attempted to collude with Russia. If they didn’t succeed, then fine. But that does not make the intent any less insidious. It is the equivalent of trying to commit a crime and failing. This is where when Trump gets cornered, if it is between him and the system, there is no question he will try to tear down the system. If politicized rule of law becomes the new normal, how do you return to normal? Trump and his allies are opening up a Pandora’s box that may serve him in the short term politically but is a massive affront to the functioning of American democracy over the long term.

You are in London now. You have also traveled all over the world. How does America under Donald Trump look to our allies and also to our enemies?

It is an unprecedented disaster in terms of America’s reputation in the world. He has decimated longstanding alliances and the country’s gravitas across the globe in a matter of months. A survey in June 2017 looked at the change of confidence in United States leadership between Obama and Trump. It fell 75 percent in Germany, 71 percent in South Korea, 70 percent in France, 57 percent in the United Kingdom and 54 percent in Japan. These statistics obscure the fact that the rest of the world sees the United States as a tragic joke. It is immensely embarrassing to be an American abroad. They don’t understand how this person was not absolutely demolished in the election.

There are also long-term strategic problems that come from what Trump has done to America. People don’t understand that “America First” is actually code for America alone. The more Trump pushes for short-term transactional diplomacy that really does not advance our long-term national interests, the more U.S. power is going to decline and the 21st century is going to be dictated by China.

Even for the people who want to have a muscular strong America in the world, Trump is an unmitigated disaster.

What scares you about America under Donald Trump? Is there anything that gives you hope for the future?

The scariest thing about Trump is the lack of backlash against him. This is enabling the Republican Party’s complicity with him and perhaps causing irreparable damage to American democracy. Trump could have been contained much more effectively if Republicans had stood up to him and upheld the values they professed for a long time in terms of democratic principles.

I am hopeful because I have many friends who did not care about politics a year ago and do now. If the American people are to save democracy, they must use their voice to impact the system. We are in a critical moment where the way that citizens behave in response to Trump will dictate whether this is a break that can be repaired or the start of some very disturbing developments and the slow death of American democracy.

The hope lies in the possibility that people stand together, and the 66 percent of the country that does not like Trump sets aside the partisan bickering and says, “We can agree that this person is not fit to be president and that the way that he is behaving is a threat to our democracy.” If this happens, then American democracy can survive and actually improve. It is the only way that Trump and what he has unleashed can potentially have a positive ending.

Zortrax M200 Plus print examples

I am getting the hang of my new 3D printer. So I’m posting the photos I promised. First is a comparison: The darker green wererat on the left is with the new printer, compared to the neon green on the right with the old printer. So, yes, for my miniatures the new printer is working fine, and better than the old one.

Next is an example of something my old printer frequently refused to do: Print half a dozen miniatures at the same time. The new one did these 6 bandits in one go without problems. I assume it has to do with the ABS printing hotter, so it still sticks to the previous layer even that layer has been printed a while ago.

The other advantage of ABS is that you can treat it with acetone vapors, which makes the surface glossy and hides imperfections. As an example the 3DBenchy model printed twice identically, with the right one being treated with acetone vapors for 1 hour. Note that for miniatures you better just use 15 minutes, after 1 hour fine parts like arms or swords tend to melt.

Finally I used a model of a bard with a lot of detail to see how it comes out. This is with 15 minutes acetone treatment. Looking closely you can still see the layers and imperfections. But remember that this is just 3 cm tall, so for this size this is as good as it gets. You can see the lute, the rapier, and even the jester’s hat is printing out fine.

Magic the Gathering Arena

I’ve been in the Magic the Gathering Arena beta for quite a while, but only this week the NDA dropped. So now I can finally express how incredibly disappointed I am with this game. In Magic Duels they had a great game which was mobile and playable for all different sorts of players, including casual and new players. And they stopped supporting that to make Magic Arena, which is solely tailored for the needs of a very small hardcore crowd.

Magic the Gathering is 25 years old this year. So over the years there have been quite a lot of digital editions of the game. And every time, after a few years Wizards of the Coast stopped support of the current platform and launched a new platform. Which means that every time any cards you had bought became useless, and you needed to start your collection all over again. One needs to be very hardcore under those conditions to invest heavily into Magic Arena. But with Magic being the original pay to win game, the people who do invest heavily have a huge advantage over those who don’t.

Because Magic Arena only features a single player vs. player mode, constructed, this mode is dominated by those hardcore players. You simply can’t start up Magic Arena and play a fun, casual game. There are neither casual PvP modes like two-headed giant, nor are there any modes to play against an AI of various difficulty levels for practice or just plain fun. There aren’t even less cutthroat competitive events, like limited mode leagues. There is only hardcore constructed, where anybody who isn’t hardcore and who hasn’t spent much on cards is just simply crushed. There doesn’t even appear to be some sort of matchmaking algorithm to even try to get people a more equal opponent.

That means that the flow of play of Magic Arena for a new player looks like this: He starts his first game, gets crushed, then gets crushed again and again, until he either uninstalls the game, or pulls out his wallet to be able to play with the big boys. My guess is that very few people will opt for the latter. It is as if the developers had carefully studied exactly what made Hearthstone such a big success and then decided to do exactly the opposite. Magic the Gathering simply isn’t such a mass market game any more that you can run a digital platform only for the hardcore.

I really don’t understand why Wizards of the Coast had to stop supporting Magic Duels, they could have kept that one going for the casual and mobile players. There is no overlap in the target audience of Magic Duels and Magic Arena. And now I am really sad that there isn’t any digital Magic game for me any more.

The best Honor 7X cases

Phone cases are about decoration, but more importantly, they’re about protecting your investment. If you drop your phone, a good phone case can be the difference between a disaster and a relief. Whenever a new phone comes out, case makers start to offer their wares as well. With the Honor 7X being a recent release, we’ll be sure to update this list as new Honor 7X cases hit the market.

There is a lot that goes into deciding on what case is right for your phone. You want to make sure your phone is protected not only from drops, but from the rigors of everyday life too. Some cases protect the phone from screen scratches as well. Whatever shape you usually find your phone in after several months, chances are, there is a case to help it NOT end up that way.

Sarah Palin’s Son Track Palin Was Arrested in Alaska on Domestic Violence Charges

This is not the first time the former governor’s son has been arrested for violent behavior.

Track Palin, oldest son of former Alaska governor Sarah Palin, was arraigned Sunday on charges of felony burglary, assault in the fourth degree and criminal mischief for causing property damage.

The charges are all related to domestic violence, of which Palin has a history.

An attorney representing Sarah Palin and her husband Todd said he was unable to comment on the situation.

“Given the nature of actions addressed last night by law enforcement and the charges involved, the Palins are unable to comment further,” attorney John Tiemessen told NBC News in a statement. “They ask that the family’s privacy is respected during this challenging situation just as others dealing with a struggling family member would also request.”

Last time Track was arrested following allegations of domestic abuse, Sarah used it as a disturbing political talking point to suggest Americans don’t have enough respect for the military.

Why companies hiring Interns, build their BRAND faster?

Why should company hire Intern?

Increase productivity: Speaking of additional manpower, setting up an internship program allows you to take advantage of short-term support. The extra sets of hands help your employees be more productive, prevent them from becoming overburdened by side projects, as well as free them up to accomplish more creative tasks or those where higher-level, strategic thinking or expertise is required.

Take advantage of low-cost labor: Interns are an inexpensive resource. Their salaries are significantly lower than staff employees, and you aren’t obligated to pay unemployment or a severance package should you not hire them on full time.Moreover, while their wage requirements are modest, they’re among the most highly motivated members of the workforce.

Benefit your small business: When looking for full time work, the top talent often go for big-name businesses. But when seeking internships, learning is the leading draw. Many candidates feel they’ll get more hands-on training, real experience, and mentoring opportunities with smaller organizations.

Advantages of doing the Internship for a student

Get Real Work Experience
The biggest benefit of internships is that they offer a safe space for students and graduates to gain work experience. This is important because most employers are reluctant to hire someone who’s never worked before, they think that with no experience, you’ll probably be unreliable and not know what to do or how to work. Of course, this creates a vicious circle with no way out which is why lots of graduates end up in completely unrelated fields.

Internships can be a great solution to this problem as they allow students and graduates to experience a real workplace. Apart from the vocational skills that interns gain, they also get lots of soft skills which are crucial to not only finding a job but succeeding at one as well.

Get a Taste of Your Chosen Field
One of the greatest advantages of internships is that they allow people to experience their industry and chosen profession. This usually has one of two effects – makes people more excited and drives them to work hard and build a successful career, or they realize it’s not the right career for them.

Boosts Your CV
Internships can also benefit your CV as they are a foolproof way to demonstrate that you have work experience, as well as other workplace skills. The skills can be relevant to your chosen profession, which is admittedly crucial in a CV, but they could also be other skills, including communication and people skills that employers value.

Helps You Choose a Specialty
An internship can help you identify a particular area in your industry or profession that you’re interested in and help you acquire more knowledge regarding this area.

Following are the major companies across the world always hiring Interns

  1. Facebook
  2. Google
  3. Qualcomm
  4. Microsoft
  5. Morgan Stanley
  6. Apple
  7. HP
  8. CISCO
  9. Deloitte
  10. JP Morgan and Chase

A walking tour of JavaBean

Software components are to software what integrated circuits (ICs) are to electronics: “black boxes” that encapsulate functionality and provide services based on a specification. Software reusability has long been a holy grail of software engineering and a major goal of object-oriented programming. Software components are designed to be reusable, even interchangeable.
JavaBeans are reusable software components for Java that can be manipulated visually in a builder tool.Practically, they are classes written in the Java programming language conforming to a particular convention. They are used to encapsulate many objects into a single object (the bean), so that the bean can be passed around rather than the individual objects.

Java Bean

A Java Bean is a java class that should follow following conventions:

  • It should have a no-arg constructor.
  • It should be Serializable.
  • It should provide methods to set and get the values of the properties, known as getter and setter methods.

Serialization

In computer science, in the context of data storage, serialization is the process of translating data structures or object state into a format that can be stored (for example, in a file or memory buffer) or transmitted (for example, across a network connection link) and reconstructed later (possibly in a different computer environment)

Serializable Objects

To serialize an object means to convert its state to a byte stream so that the byte stream can be reverted back into a copy of the object. A Java object is serializable if its class or any of its superclasses implements either the java.io.Serializable interface or its subinterface, java.io.Externalizable. Deserialization is the process of converting the serialized form of an object back into a copy of the object.

Why use Java Bean?

According to Java white paper, it is a reusable software component. A bean encapsulates many objects into one object, so we can access this object from multiple places. Moreover, it provides the easy maintenance.

JavaBeans Properties

A JavaBean property is a named attribute that can be accessed by the user of the object. The attribute can be of any Java data type, including the classes that you define.

A JavaBean property may be read, write, read only, or write only. JavaBean properties are accessed through two methods in the JavaBean’s implementation class −

S.No. Method & Description
1
getPropertyName()
For example, if property name is firstName, your method name would be getFirstName() to read that property. This method is called accessor.
2
setPropertyName()
For example, if property name is firstName, your method name would be setFirstName() to write that property. This method is called mutator.
A read-only attribute will have only a getPropertyName() method, and a write-only attribute will have only a setPropertyName() method.

JavaBeans Example

Consider a student class with few properties −

package com.SuvenConsultants;

public class StudentsBean implements java.io.Serializable {
private String firstName = null;
private String lastName = null;
private int age = 0;

public StudentsBean() {
}
public String getFirstName(){
return firstName;
}
public String getLastName(){
return lastName;
}
public int getAge(){
return age;
}
public void setFirstName(String firstName){
this.firstName = firstName;
}
public void setLastName(String lastName){
this.lastName = lastName;
}
public void setAge(Integer age){
this.age = age;
}
}
How to Access Java Bean Class

package com.SuvenConsultants;
public class Suven{
public static void main(
String args[]){

StudentsBean sc=new StudentsBean ();//object is created

sc.seFirsttName("Rocky");//setting value to the object
sc.seLasttName("Jagtiani");
System.out.println(e.
getFirstName());

}}
The useBean action declares a JavaBean for use in a JSP. Once declared, the bean becomes a scripting variable that can be accessed by both scripting elements and other custom tags used in the JSP. The full syntax for the useBean tag is as follows:

<jsp:useBean id = "bean's name" scope = "bean's scope" typeSpec/>


Here values for the scope attribute can be a page, request, session or application based on your requirement. The value of the id attribute may be any value as a long as it is a unique name among other useBean declarations in the same JSP.

Following example shows how to use the useBean action −

<html>
<head>
<title>useBean Example</title>
</head>

<body>
<jsp:useBean id = "date" class = "java.util.Date" />
<p>The date/time is <%= date %>
</body>
</html>

You will receive the following result − −

The date/time is Thu Sep 30 11:18:11 GST 2017 

Accessing JavaBeans Properties

Along with action, you can use the action to access the get methods and the action to access the set methods. Here is the full syntax −

<jsp:useBean id = "id" class = "bean's class" scope = "bean's scope">
<jsp:setProperty name = "bean's id" property = "property name"
value = "value"/>
<jsp:getProperty name = "bean's id" property = "property name"/>
...........
</jsp:useBean>

The name attribute references the id of a JavaBean previously introduced to the JSP by the useBean action. The property attribute is the name of the get or the set methods that should be invoked.
Following example shows how to access the data using the above syntax −

<html>
<head>
<title>get and set properties Example</title>
</head>

<body>
<jsp:useBean id = "students" class = "com.SuvenConsultants.StudentsBean">
<jsp:setProperty name = "students" property = "firstName" value = "Rocky"/>
<jsp:setProperty name = "students" property = "lastName" value = "Jagtiani"/>
<jsp:setProperty name = "students" property = "age" value = "39"/>
</jsp:useBean>

<p>Student First Name:
<jsp:getProperty name = "students" property = "firstName"/>
</p>

<p>Student Last Name:
<jsp:getProperty name = "students" property = "lastName"/>
</p>

<p>Student Age:
<jsp:getProperty name = "students" property = "age"/>
</p>

</body>
</html>

The following result will be displayed −

Student First Name: Rocky

Student Last Name: Jagtiani

Student Age: 39

Benefits of JavaBeans:

  • A Bean obtains all the benefits of Java’s “write-once, run-anywhere” paradigm. 
  •  The properties, events, and methods of a Bean that are exposed to an application builder tool can be controlled. 
  • A Bean may be designed to operate correctly in different locales, which makes it useful in global markets.
  •  Auxiliary software can be provided to help a person configure a Bean. This software is only needed when the design-time parameters for that component are being set. It does not need to be included in the run-time environment.
  •  The configuration settings of a Bean can be saved in persistent storage and restored at a later time. 
  • A Bean may register to receive events from other objects and can generate events that are sent to other objects.
