Actually, I don't see any drawback with my current implementation: - for Jetty/HSQLDB, my plugin installs the extension correctly, both in the "data/extensions" directory and in the database. - for the WAR packaging, Distribution Wizard is already started during the first execution.

Bundling the dependencies in some directory inside the WAR has not much sense here, since we already don't do it for XAR extensions. Except if we want to be able to run DW without an Internet connection, and in this case we should also include all needed XARs. But again, it does not make much sense: we won't bundle all possible flavors. What we only needs is to put my plugin in contrib or in platform, but for doing it properly we need to do some refactoring with Thomas.
