As a byproduct it provides a JMX interface for the completed system.
This talk will cover how to benefit from unit testing with
JMX, and the code and overhead required to use the technique.

Synchronizing Properties with Beans Binding (JSR 295)
The idea of setting up listener relationships between your GUI models, views, and controllers is simple enough, but grinding the same "glue" code dozens or even hundreds of times is wasteful and error-prone. JSR-295, Beans Binding, offers relief from the drudgery. In this article, John O'Conner shows how it works and what it can do for you.

The Open Road: Superpackages
Wonder what the relationship between com.example.package and com.example.package.test is? There isn't one! This lack of an orderly package-visibility relationship has made life difficult for a number of programmers trying to balance organizational needs against practical concerns. In this entry of "The Open Road," Elliotte Rusty Harold takes a look at how JSR 294 ("superpackages"), intended to be part of Java SE 7, proposes to fix this problem.

Query by Slice, Parallel Execute, and Join: A Thread Pool Pattern in Java
Pagination is a much-needed feature; one that's harder than it looks. For large datasets, reading all results into memory is impractical, if not dangerous, but only fetching small chunks can make it difficult to apply business logic across all results. Binildas C. A. shows how to combine the database's ROWNUM function with Java SE 5's thread pools to create highly effective pagination.
