JavaBlackBelt

JavaBlackBelt offers Java developers that chance to prove their skills with Java and related technologies, including EJB, Hibernate, Struts, Spring, Servlet/JSP, Tomcat, Ant, Design Patterns, JSF, JUnit, JDBC, Swing, XDoclet, Architecture, WebLogic, JavaScript, SWT/JFace, and XML Parsing.

It takes nine months on average for a non-java developer to be comfortable in writing a typical business application with Java," company information states.  With JavaBlackBelt, the company wants to give Java developers an alternate way to measure and demonstrate their  technical skills. The classic way to measure and demonstrate skills (apart from successfully finishing a project) is through certifications. Sun Microsystems prop... (more)

Java Kicks Ruby on Rails in the Butt

This article tries to demonstrate that Java can be more productive than Ruby. We are going to develop the same application of the article Rolling with Ruby on Rails Revisited (part 1 [1] and part 2 [2]) but using POJO [3]s annotated with JPA [4] and a Model Driven Framework, OpenXava [5] in this case. The result is that with less code, and less time you obtain a more powerful application. Ruby and rails: The regressive framework Ruby on rails [6] is so elegant, so easy, so productive. I cannot avoid read and heard continuously these comments. For example, the article Rolling with ... (more)

Anatomy of a Java Finalizer

A couple of patterns that could cause Java heap exhaustion were identified from years of research at IBM. One interesting scenario was observed when Java applications generated an excessive amount of finalizable objects whose classes had non-trivial Java finalizers. What Is a Java Finalizer? A Java finalizer performs finalization tasks for an object. It's the opposite of a Java constructor, which creates and initializes an instance of a Java class. A Java finalizer can be used to perform postmortem cleanup tasks on an instance of a class or to release system resources such as file... (more)
