Jesse Kuhnert commented on TAPESTRY-2055:
-----------------------------------------
Now that I think about it more your second error message about duplicated
tapestry-annotation definitions sounds suspicious. It should only see the
other hivemodule.xml definition if it is on the same classpath - which means
the classpath hasn't really been separated for both web apps. I have a server
running multiple tapestry war'ed apps with no shared libs and don't get the
duplicated error message so am thinking that there are still some jars being
shared somehow in your environment.
