1. TDA Thread Dump Analyze   
The TDA Thread Dump Analyzer for Java is a small Swing GUI for analyzing Thread Dumps and Heap Information generated by the Sun Java VM (currently tested with 1.4.x, 1.5.0_x and 1.6.0_x releases). It parses the thread dumps and class histograms from a provided log file. TDA needs at least Java 1.4.2_x to run.

It provides statistic informations about the found thread dumps, gives information abo... more

2. Validate Java EE Annotations with Annotation Processors   
Annotations are one of Java 5's most compelling features, but their openness is in some ways a curse: there's nothing keeping you from declaring illegal combinations of annotations (like @Stateful and @Stateless). Annotation processors give you the opportunity to inspect annotations, either with the currently available Apt or or the upcoming JSR-269 annotation processor. Jason Li takes a look at b... more

3. Understanding Weak References   
Weak references have been around for a long time, but they still aren't widely understood. If you don't understand weak references as well as you'd like (or at all!), read on.

6. Managing Component Dependencies Using ClassLoaders   
Java's class loading mechanism is incredibly powerful. It allows you to leverage external third-party components without the need for header files or static linking. You simply drop the JAR files for the components into a directory and arrange for them to be added to your classpath. Run-time references are all resolved dynamically. But what happens when these third-party components have their own ... more

7. Internals of Java Class Loading   
When are two classes not the same? When they're loaded by different class loaders. This is just one of many curious side effects of Java's class-loading system. Binildas Christudas shows how different class loaders relate to one another and how (and why) to build your own custom class loader.

8. Pool resources using Apache's Commons Pool Framework   
Resource pooling is not new and is being widely used to conserve and optimize the usage of resources like threads, sockets, and database connections. Web server implementations routinely use thread pool implementations for performance and scalability reasons. Commons Pool, from the Apache Software Foundation, may not be the first when it comes to implementation, but it deserves its own place for d... more

9. Validating Objects Through Metadata   
Metadata, in the form of J2SE 5.0's annotation, allow you to mark up your your code with declarative information, and then use reflection to pull out those annotations at runtime and use them. Jacob Hookom shows how these techniques can be used to validate input to your application.
