XDoclet is basically just a code generation tool. Many applications have redundant code and/or interfaces and this is where XDoclet comes into play. You can update one source file and use XDoclet to regenerate the affected files. The incredible improvements to content management are clearly obvious. XDoclet parses source code like JavaDoc. By reading JavaDoc tags embedded in source code, XDoclet uses predefined templates to generate code based on those tags. A common use of XDoclet is to embed tags in EJB’s and automatically generate all of the interfaces, beans, and XML descriptors.

This tutorial shows J2EE developers how to use XDoclet to speed development. XDoclet simplifies continuous integration between components using attribute-oriented programming.

If you are a J2EE development veteran, then you realize keeping code in sync with deployment descriptors can be a drag. Often you may need to reuse components with other applications or in other environments like other application servers or with other database systems. You need to keep separate deployment descriptor for each application/environment combination, even if only one or two lines of the large deployment descriptor changes, you need to have a deployment descriptor for every possible configuration.
