XDoclet is a Java 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 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. XDoclet lets you apply Continuous Integration in component-oriented development. Developers should concentrate their editing work on only one Java source file per component.
