Thanks for a great tool!
I would like to see a cleaner xdoclet-build.xml. Perhaps you could give the choice to import the required jar files for building J2EE applications into the project. Now the build.xml contains static links to MyEclipse installation directory. I would like to be able to check out the project from CVS and directly build on Linux, Windows etc.. I like it when the project has no external dependencies, except the Java SDK.
This will also help setting up a host doing nightly builds
In other projects we have stopped using XDoclet-generation when the project has matured. We put the generated source (VO, Interfaces …) in CVS and continue working on them.
