I havent seen anything like that. Not for download and not building from source. The maven build process can only generate Tomcat 5/6 and Jboss 7 distributions. There is also no mention of such thing in the docs, or how you can create it.
For example, idp-standalone-1.0.3.SP1.war does not contain jars or classes.
Another question, while trying to understand the source tree, I see the entry point java clases
in a couple of places in the source tree
What is the right place to get them from if I want to build my own war?
