p.s.
When I do a clean, I additionally get these entries in the server log:
Full publish failed for module jbosscache-core.jar
Full publish failed for module jgroups.jar
Full publish failed for module my_foo.jar
Full publish failed for module jxl.jar
Full publish failed for module saxon9.jar
Some of these jars are placed in the /lib directory of my ear file, some are in the .classpath of the webmodule and targetted to be included in WEB-INF/lib.
Upon inspection, nothing is special about these libraries. There are for instance more libraries in the /lib of the ear, and there are no Full publish failed for them. In this case, the jars for which Full publish failed are in the deployment.
What does this message exactly mean, and how can I find out what really goes wrong?
