• Ed Burns' Servlet 4/HTTP 2 Session at JavaOne 2014

  - by reza_rahman

  For the Java EE track at JavaOne 2014 we are highlighting some key sessions and speakers to better inform you of what you can expect, right up until the start of the conference. To this end we recently interviewed Ed Burns. Ed is a veteran of Sun and now Oracle. He has been and is instrumental in pushing the JSF ecosystem forward as specification lead. Besides his specification lead work Ed is well regarded as an author and speaker on his own right. In addition to carrying the JSF torch Ed will be co-leading the key Servlet 4 specification for Java EE 8, along with Servlet specification guru Shing Wai Chan. The primary goal of Servlet 4 is to enable the fundamentally important changes in HTTP 2 for the entire server-side Java ecosystem. We wanted to talk to Ed about his Servlet 4 session at JavaOne 2014 and HTTP 2 generally: The details for the Servlet 4 session can be found here. Ed has several other key sessions on the track that we hope to talk to him about separately in the near future: What’s Next for JSF?: In this key session, Ed will be sharing the next steps for the continued evolution of the JSF specification in Java EE 8. Where’s My UI? The 2014 JavaOne Web App UI Smackdown: The UI space for web applications, especially in the Java ecosystem continues to be as hotly contested as ever. This is especially true with the (re)introduction of JavaScript based rich client frameworks like AngularJS. This lively panel brings together experts representing the diverse schools of thought for web UIs. Ed will be representing JSF of course. Neal Ford will moderate the panel as an independent and hopefully reasonably neutral party. Adopt-a-JSR for Java EE 7 and Java EE 8: Adopt-a-JSR has been a reasonable success for Java EE 7. With Java EE 8 we are planning to strengthen it far more as away of getting grassroots level participation in the specification efforts. This session will introduce Adopt-a-JSR, share how it worked for Java EE 7 and what we plan to do with it in Java EE 8. Ed will be sharing his perspectives on Adopt-a-JSR for both Java EE 7 and Java EE 8. Besides Ed's sessions, we have a very strong program for the Java EE track and JavaOne overall - just explore the content catalog. If you can't make it, you can be assured that we will make key content available after the conference just as we have always done.

• How to send credentials to linkedIn website and get oauth_verifier without signing in again [closed]

  - by akash kumar

  I am facing a problem sending credentials to another website so that I can login the user (automatically, not clicked on sign in here) and get an oauth_verifier value. I want to send the email address and the password through a form (submit button) from my website (e.g. a Liferay portal) to another website (e.g. LinkedIn), so that it automatically returns an oauth_verifier to my website. That means I don't want the user of my website to submit his email and password to LinkedIn again. My goal is to take the email and password of the user in my website and show the user his LinkedIn connection, message, job posting (again, in my website, not LinkedIn). I dont want the user redirected to the LinkedIn website to sign in there and then come back to my website. I have taken a consumer key and a secret key from LinkedIn for my web aplication. I am using the LinkedIn API and getting oauth_verifier for access token but in order to login, I have to take user to LinkedIn to sign in, while I want it to happen in the backend.

• exact answer for “what is j2ee?” - job interview

  - by shuuchan

  I'd like to ask if someone of you knows the exact meaning of JEE. That's because a collegue of mine was asked this question in a job interview, and was "unable to answer properly"... to speak with his interwiewer's words. And when he told me what he said to his interviewer I got really surprised, since it was more or less what I would have answered myself - in a concise form, the first paragraph of this article. J2EE (Java 2 Platform, Enterprise Edition) is a Java platform designed for the mainframe-scale computing typical of large enterprises. Sun Microsystems (together with industry partners such as IBM) designed J2EE to simplify application development in a thin client tiered environment. J2EE simplifies application development and decreases the need for programming and programmer training by creating standardized, reusable modular components and by enabling the tier to handle many aspects of programming automatically. That seems not to be enough, since the interviewer asked for "more precise and less general definition". Is there really a more precise definition for JEE? Or did my colleague just find the fussiest-interviewer-ever? :)

  - by Satish Pandey

  I am using the combination of spring, spring-security, struts and iBatis in my application. Now I am looking to migrate the struts UI to GWT. The new combination must be spring, spring-security, GWT and iBatis. I applied a layered approach to develop my application. In Controller/UI layer i am using Struts. I want to replace struts and use GWT in Controller/UI layer. Is is possible to use GWT without affecting another layers DAO/BL/SL?

• Programming in academic environment vs industry environment [closed]

  - by user200340

  Possible Duplicate: Differences between programming in school vs programming in industry? This is a general discussion about programming in the industry environment. The background story is that my colleague sent me a very interesting article called "10 Things Entrepreneurs Don’t Learn in College." The first point in that post is about the author's experience of programming in the academic environment vs industry environment. After finishing a 4 year Computer Science degree course, I am currently working in the academic environment as a developer, mainly writing Java, J2EE, Javascript code. I know there are differences between academic programming and industry programming, but I was shocked after reading that post. Trying to avoid this happening on me in the future, or the others. Can anyone from industry give some general advice about how to program in industry. For example, What exactly happens when a task is received? What is the flow from the beginning to the end? What are the main differences between the programming in industry and academia? Is it more structured? Are more frameworks used? It would be great if some code examples could be given. Thanks.

• Identify memory leak in Java app

  - by Vincent Ma

  One important advantage of java is programer don't care memory management and GC handle it well. Maybe this is one reason why java is more popular. As Java programer you real dont care it? After you meet Out of memory you will realize it it’s not true. Java GC and memory is big topic you can get some information in here Today just let me show how to identify memory leak quickly. Let quickly review demo java code, it’s one kind of memory leak in our code, using static collection and always add some object. import java.util.ArrayList;import java.util.List; public class MemoryTest { public static void main(String[] args) { new Thread(new MemoryLeak(), "MemoryLeak").start(); }} class MemoryLeak implements Runnable { public static List<Integer> leakList = new ArrayList<Integer>(); public void run() { int num =0; while(true) { try { Thread.sleep(1); } catch (InterruptedException e) { } num++; Integer i = new Integer(num); leakList.add(i); } }} run it with java -verbose:gc -XX:+PrintGCDetails -Xmx60m -XX:MaxPermSize=160m MemoryTest after about some minuts you will get Exception in thread "MemoryLeak" java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:2760) at java.util.Arrays.copyOf(Arrays.java:2734) at java.util.ArrayList.ensureCapacity(ArrayList.java:167) at java.util.ArrayList.add(ArrayList.java:351) at MemoryLeak.run(MemoryTest.java:25) at java.lang.Thread.run(Thread.java:619)Heap def new generation total 18432K, used 3703K [0x045e0000, 0x059e0000, 0x059e0000) eden space 16384K, 22% used [0x045e0000, 0x0497dde0, 0x055e0000) from space 2048K, 0% used [0x055e0000, 0x055e0000, 0x057e0000) to space 2048K, 0% used [0x057e0000, 0x057e0000, 0x059e0000) tenured generation total 40960K, used 40959K [0x059e0000, 0x081e0000, 0x081e0000) the space 40960K, 99% used [0x059e0000, 0x081dfff8, 0x081e0000, 0x081e0000) compacting perm gen total 12288K, used 2083K [0x081e0000, 0x08de0000, 0x10de0000) the space 12288K, 16% used [0x081e0000, 0x083e8c50, 0x083e8e00, 0x08de0000)No shared spaces configured. OK let us quickly identify it using JProfile Download JProfile in here  Run JProfile and attach MemoryTest get largest size of  Objects in Memory View in here is Integer then select Integer and go to Heap Walker. get GC Graph for this object  Then you get detail code raise this issue quickly now.  That is enjoy it.

• Best Persistence choice for J2EE-App with frequently changing Data Model

  - by Ben-G

  Whenever I develop a J2EE-Application, I at some point decide to switch from my dummy Persistence (Simply Using Lists and other Data Structures) to some Sort of Database Persistence. Mostly when I hope the Data Model is more or less complete. From this point on, changes to the data model become exhausting, but unluckily they occur rather often. I've used different Object-Relational-Mappers (iBatis, Hibernate) for my projects. They definitely reduce the pain coming with Data Model changes, but they anyway let me adjust code/configuration at 3 or 4 places for every single change. To me, that's cumbersome and error prone. I made a better experience with DB4O, which simply persists Java Objects as they are, but I believe it's performance does not scale for huge applications. Is there anyway to maintain performance while letting out all the ugly configuration work? I'm seeking a performant framework which really hides persistence from my code. Wish for thinking? Or am I missing out THE technology? Hope you can help.

• JEE frameworks, a road map to learn? and should I learn them?

  - by vibhor

  Background Information I have been into programming since past 1 years professionally, my day to day work includes writing BIRT reports, designing and validating forms using JEE (struts/spring, hibernate). I don't have a comp Sci 4 year degree (Electronics), so I have very Limited experience in comp Sci. Question JEE frameworks (struts1/2, spring, hibernate etc) are hot nowadays, however java world have a tendency of building A4j, B4J... mayway4J kind of stuff (and I am tired of it). AFAIK, frameworks are nothing but bunch of XML config files and hundreds of classes built to cram (by developer). And sooner then later a new framework come into picture that says I am the best among all. So My Question is - 1.What will you do to learn a framework (many frameworks) considering that it can be obsolete till you'll be master in it (Learning frameworks can take significant amount of time)? 2.Considering early into your career, will you give a damn that how well someone knows framework (knowing frame work is important but still..) and why/how should I learn a framework knowing I have to (un)learn it in order to learn other one (plenty of of 4Js....)? I am just trying to get a big picture, that, if you're in place of me, what would be your learning/cramming strategy (Road map)? I am not intended to start a holy war between A versus B, (frameworks are more or less essential).

• Node.js Or servlets?

  - by Nilesh

  I have heard a lot and read about the Javascript server side language i.e Node.js, and saw many comparisons in favor of Node. I don't understand what makes it better or faster, or how it even relates to something as mature as Java Servlets. But Servlets are built on top of a multithreaded programming language as opposed to Node.js. Then how can node.js be faster? If suppose 1000K users query for a database records, then shouldn't Node.js be slower than Servlets. Also Don't servlets have better security compared to Node.js?

  I used to develop in Django/Python and Rails/Ruby (and before that C/C++ and C#), and I'm now at a job where we do enterprise Java development (Spring, Hibernate, RESTEasy, Maven, etc.) for web applications and web services. Coming from the Convention over Configuration world, what's the best way to get up to speed doing enterprise Java web services development? I know Java (the language) well, and I've written GUIs in Swing and basic JSP before, but nothing of the kind I'm doing now. Are there any recommended tutorials to get up to speed on popular Java enterprise development tutorials?

• Why is web app development path in Java this much confusing? [closed]

  - by Farshid

  I'm currently a .net web developer and I really like to switch to Java. I've used JSP about 7 years ago to develop and deploy a small web application on a JRUN app server. But after 7 years that I like to return back to Java, I can't find the clue. There are many web development frameworks that exist in Java world and each of them has fans that recommand it. There are extensions that sit above jvm for web development (like jRuby i think). I am confused and I do not know where to start the path of learning java web development. I do not want to focus on custom tailor-made approaches and want to remain on the basic path of developing with standard tools and methods and deploy them into standard app servers. (For example some says do not use EJBs, some says focus on MVC facilities like JSF. I'm confused and I do not know the path that i should go on)

• How to get started in coding for JBoss

  - by Mister IT Guru

  I have an idea on how to revamp our internal application, after having accessed the needs of the users, addressing thier current issues, and the like. But I am not a coder. My last application I wrote was in college, in C, (java wasn't invented-ish!) and it was a booking system, with the option to add on other modules, blah blah. I got an A, but I became a system administrator instead, more intrested in designing and maintainend networks and infrastructure, but with the advent of virtualisation, and linux management tools such as puppet I can now manage infrastructure in my sleep! Now I want to write code - to put on my infastructure, and I want to build .... a booking system! This is just to get experience, but I am at a loss as to where to start. Setting up the environment, will take me about a day. Writing the spec, even how I want it to work, I already know, but as for actually coding in a decent manner, I can only guess. If anyone can recommend a book, website, blog, twitter person to follow, or just advice on how to build a kick butt basic jboss app, then please, "I AM READY TO LEARN" :)
