This article will teach you how to analyze a JVM Thread Dump and pinpoint the root cause of your problem(s). From my perspective, Thread Dump analysis is the most important skillset to master for any individual involved in Java EE production support. The amount of information that you can derive from Thread Dump snapshots is often much beyond than what you can think of. My goal is to share with you my knowledge on Thread Dump analysis that I accumulated over the last 10 years e.g. hundreds of Thread Dum... (more)

« Jira Remote API Calls – Making life easier This weekend I wanted to experiment with a cloud solution for Java. In the past I tried out Google App Engine, but although easy and fast, it forces you to use the Google API and has some limitations. This time, the criteria for the platform was running nearly anything in a web container. And I think I found the perfect match…Introducing Jelastic Jelastic is the next generation of Java hosting platforms which can run and scale ANY Java application with no c... (more)

Data exchanges between companies increase a lot. The number of applications which must be integrated increases, too. The interfaces use different technologies, protocols and data formats. Nevertheless, the integration of these applications shall be modeled in a standardized way, realized efficiently and supported by automatic tests. Three integration frameworks are available in the JVM environment, which fulfil these requirements: Spring Integration, Mule ESB and Apache Camel. They implement the well-kn... (more)

Wednesday, April 18, 2012 6:21:10 AM GMT Sunday, March 11, 2012 9:24:37 AM GMT
Object Oriented Design Principles are core of OOPS programming but I have seen most of Java programmer chasing design patterns like Singleton pattern , Decorator pattern or Observer pattern but not putting enough attention on Object oriented analysis and design or following these design principles. I have regularly seen Java programmers and developers of various experience level who either doesn't heard about these OOPS and SOLID design principle or simply doesn't know what benefits a particular design p...

•What is a JVM? JVM is Java Virtual Machine which is a run time environment for the compiled java class files. •How to define a constant variable in Java? The variable should be declared as static and final. So only one copy of the variable exists for all instances of the class and the value can't be changed also. static final int PI = 2.14; is an example for constant. •I don't want my class to be inherited by any other class.

Short Circuit Evaluation of Java's Boolean Operators ~ Java Stuff

published 734 days, 2 hours, 42 minutes ago posted by javastuffjavastuff 740 days, 16 hours, 34 minutes ago
Monday, April 16, 2012 5:46:12 AM GMT Monday, April 09, 2012 3:54:12 PM GMT
The && and || operators are short circuit operators. A short circuit operator is one that doesn't necessarily evaluate all of its operands. Take, for example, the operator &&. What happens when Java executes the following code? if (0 == 1 && 2 + 2 == 4) { out.println("This line won't be printed."); } You might expect Java to ask itself if 0 equals 1, and then ask if 2 + 2 equals 4. But with Java's && operator, that's not what happens. Instead, Java does t... (more)

In Part 1 of Scala: Sink or Swim? we looked at some things you should ignore in the Scala ecosystem when you are starting to adopt Scala. I think it was important getting that out of the way first — if you discover these things as you’re learning, thinking that’s idiomatic Scala, they might scare you off, and you would be missing out, in my opinion. In this post we’ll look at some more things that are not quite perfect in Scala land, but that you must simply live with, at least for now. Finally, in Part ... (more)

I created a Git project to use it as simple startup for Camel-Scala-Maven projects using just the basic Camel concepts and only a few complex Scala features (i.e. very „Java-friendly“).Problems when Starting with this Combination I had several problems finding good resources for starting when I first tried to combine them.

Monday, April 16, 2012 5:46:12 AM GMT Monday, April 09, 2012 11:08:46 AM GMT
JUnit is the defacto Java unit testing framework, but there's a couple of new (and not so new) frameworks out there for web development that might be of interest. Questions you might want to ask yourself prior to adoption: Are they fast and easy to develop and therefore low cost? Are they fast to run and therefore encourage adoption? Do they require maintenance and therefore engender on going cost? Can I execute them in my nightly build? Do they ultimately allow you to write more bug free code, faster? (more)

Difference between window.onload and onDocumentReady? The onload event does not fire until every last piece of the page is loaded, this includes css and images, which means there’s a huge delay before any code is executed. That isnt what we want. We just want to wait until the DOM is loaded and is able to be manipulated. onDocumentReady allows the programmer to do that. 2. What is the difference between == and === ? The == checks for value equality, but === checks for both type and value. 3. Wha... (more)

ZeroTurnaround is proud to announce Frostbyte, a new stack-based language for the JVM. The language was born out of frustration of working with the standard Java software stack and tools. Hopefully this language will be the long awaited answer to the myriad of JVM languages that have hit the streets in the past couple of years. With some confidence, we believe that Frostbyte will solve both social and engineering problems th... (more)

Java 7's Support for Suppressed Exceptions | Javalobby

Friday, April 13, 2012 12:50:40 PM GMT Monday, April 09, 2012 11:09:55 AM GMT
A new constructor and two new methods were added to the Throwable class (parent of Exception and Error classes) in JDK 7. The new constructor and two new methods were added to support "suppressed exceptions" (not to be confused with the bad practice of swallowing or ignoring exceptions). In this post, I look at why these methods were introduced and how they are used in JDK 7. I throw in a short discussion on how suppressed exceptions are different than chained exceptions. Suppressed exceptions play a si... (more)
