In this article, an excerpt from Test-Driven Development: AJ2EE Example (Apress, 2004), author Thomas Hammell helps youselect the right tools for getting started with test-drivendevelopment (TDD).

Today, I'd like to take a look at two different ways to create a poll component. Poll components are a way to periodically update a page with new information.

One of the really cool features of MobileMe and the new iPhone 3.0 OS is the ability for it to reach out and locate your iPhone at any time if you have that feature enabled. Right now Apple only makes this available on their MobileMe website however and does not offer a programmatic way to get a hold of the information.

JVM's seldom used feature shutdown hooks provide the ability to clean up resources

A few months ago, development on the new console for jBPM started. Initially, it was the intention that this console could also serve as the next console for jBPM 3 with the jBPM 3.3 branche initially being the target. Not much later, it was decided to only develop this console for jBPM 4 and the jBPM 3.3 branch was discontinued and 3.2 was the main stable branche again.

Many of us have had to ponder this question. Technology selection is notoriously difficult in the enterprise space since the criteria and complexity of the problem is often not fully understood until later in the development process.

This article describes how to use Portal Pack plugins to create and modify Sun GlassFish Web Space Server/Liferay themes on NetBeans IDE (Integrated Development Environment).

A lot of us heard the word cache and when you ask them about caching they give you a perfect answer but they don’t know how it is built, or on which criteria I should favor this caching framework over that one and so on, in this article we are going to talk about Caching, Caching Algorithms and caching frameworks and which is better than the other.

While lying in bed and trying to sleep last night, I had an idea I'd like some feedback on. The idea is partially destructive garbage collection, which allows the runtime to handle caching, instead of the programmer. With PDGC, the runtime is allowed to destroy an object and keep only the relevant data for recreation around.

Today i’m going to talk about setting up the development environment for running the augmented reality demo shown in this video from my previous post.

Using the annotation @EJB is not enough for glassfish to inject a new instance of a java bean in my class. Local EJBs are stored in the local naming service java:com/env and I haven't figured out why the Glassfish is refusing to use the same methodology as it use for remote beans.

Mule is one of the mature ESBs in the market and CXF facilitates rapid development of web services. Together they ease the realization of service oriented architecture across organizations (applications). About the example: The example is about a web application invoking the CXF web service exposed by the BookStoreCentral application to retrieve the least available price for the book. ISBN of the book is passed as the input to BookStoreCentral which returns a Book object populated with the least available price.

This demonstrates the JavaFX to JavaScript and JavaScript to JavaFX interaction. A cool way to leverage JavaFX and browser/Web page communication.

Here are some quotes about running Rails applications on GlassFish from user@jruby mailing list...

One of my tasks for the Fusion Middleware 11g launch event was to build the JDeveloper/ADF part of the demo (along with Juan).

The latest version of SpringSource Tool Suite (STS), an Eclipse-based development environment for building Spring applications, supports Spring 3.0 and OSGi Development Tools. SpringSource development team recently announced the release of the first Release Candidate of SpringSource Tool Suite 2.1.0 version. The new version also supports run time integration with Amazon EC2 and VMware tools.

This sample J2ME demonstrates the use of Canvas in a midlet. Most of the graphics methods available are used here to let you quickly learn the concepts of graphics programming in J2ME program. It also shows the basics of creating a J2ME game using the controls of a phone. For example handling the left, right keys and the up, down keys etc.

The point (x, y) specifies to a drawing function a location relative to the point (0, 0). The point (0, 0) is the origin of the Graphics. When you first obtain a reference to your canvas Graphics, its origin, the point (0, 0), always represents the top-left corner of the device's display (the destination).

Spring 2.5.x introduces annotated controller that makes web development with Spring MVC a lot easier. No more XML is required for each controller you define. Spring MVC's annotated controller reminds me of Ben Parker's famous quote: "With great power comes great responsibility". What's the great responsibility of using the annotated controller? The validation!! With the old base-controller-classes approach you can just inject validators to your form controller and Spring MVC will take care of the validation for you. With annotated controller, this validation mechanism is removed. The common way to do validation with annotated controller is to inject Validator objects into your annotated controller and use its validate() method on the bean you want to validate. It's painful to write these validation steps manually in every request method. Luckily, with Spring 2.x's @Aspect, we can write a nice validation mechanism for our annotated controllers.

Article explaining how to test for an exception,test for the execution time of a method. Also explains the @Ignore annotation for disabling a test. Article talks about the basic features of JUnit.

Are you fed up with launching your heavy-weighted java eclipse IDE when you just need to create a quick java class to do some testing ? Do you miss your little notepad but need a little twist ? Or maybe you’re just learning Java with an amazing editor like BlueJ which still lacks code generation. Using this lighweight text DSL or Domain Specific Language is a solution which will hugely improve your productivity (especially if you wrap it inside a snippet protocol).

Induction is a high performance, open source, request-based MVC web application framework for Java supporting dynamic application reloading, type-based dependency injection, dependency analysis between models, views and controllers (using any popular IDE) and an extensible architecture. Induction is possibly the only request-based Java MVC web framework that supports full dependency analysis between models, view and controllers.
