You can find XDoclet at http://xdoclet.sourceforge.net Maybe this question should belong to the ANT forum since XDoclet is really an ANT task. Anyhow, XDoclet is primarily used to generate "boiler-plate" code. It does this by scanning through your source for metadata information in the form of @tags (similiar to javadocs). If this is what you are looking for, their web site can tell you more about it. Hope this helps.
