Jakarta Commons Chain

The Jakarta Commons Chain framework is a fairly new framework that implements the Chain of Responsibility pattern. In this article, the basics of the framework are discussed, starting with the interfaces Command, Chain, and Catalog. In addition, the reader is introduced to some packages designed for use in Web applications and learns how Commons Chain will be applied in an upcoming version of Struts. Finally, some imperfections are mentioned that are still present at the time of this writing.
rating comment: Nice overview of the Commons Chain framework, though I miss comments on applying this in realworld applications. Okay there is an example of Struts applying it (which reminds me of the Interceptors notion of JBoss AS), but I'd have preferred to read more about applying it in other applications. Nevertheless good article!
