Interesting story...
do you have any time for a howto-ear-packaging?
I think it would be a good thing for people coming after you

|Subject: [jBoss-User] Cautionary Tale
|
|
|I have a cautionary tale for anyone who has an existing app with a web
|component and an ejb component that runs with tomcat and jboss :
|
|With the release of the J2eeDeployer and the EmbeddedTomcatService my
|App stopped working completely. I started getting
|ClassNotFoundExceptions thrown when my jsps were accessed. It made no
|sense as the app ran fine with tomcat and jboss in either separate vms
|or with the existing TomcatService module. It even ran with the
|pre-release version of the EmdeddedTomcatSevice that required the code
|change to Tomcat 3.2Beta. I having been pulling my hair out trying to
|figure out what was going wrong.
|
|I finally figured out what it was. It was how I have been packaging my
|war file and ejb-jar file. It turns out that I have been a bit lapse in
|what class files I include in both of these. My web app use a mvc jsp
|framework called struts. To use it you have to include a jar file in the
|lib directory of the war file. You write your own code that extends some
|of the classes in this lib jar file. This was my problem. I included (by
|accident) some of these child classes in my ejb-jar. When my jsps tried
|to load them I got ClassNotFoundExcpetions thrown becuase of the
|relationship (I assume) between the EJB container classloader and the
|webapp classloader. By removing these classes file from the ejb-jar file
|fixed the problem.
|
|Moral of the story : Be careful how you package the jar, war and ear
|files.
