XDoclet: Attribute-Oriented Programming - Welcome: "XDoclet is an open source code generation engine. It enables Attribute-Oriented Programming for java. In short, this means that you can add more significance to your code by adding meta data (attributes) to your java sources. This is done in special JavaDoc tags.
XDoclet in Action
XDoclet will parse your source files and generate many artifacts such as XML descriptors and/or source code from it. These files are generated from templates that use the information provided in the source code and its JavaDoc tags."
