ClassNotFound in .par when using <loader-repository>

bigm25 Aug 18, 2005 4:27 AM

When i try to enable "scoped classloading" by adding the famous "<loader-repository>" to jboss-app.xml in the META-INF of my .ear,
JBoss fails to deploy the .par which is contained in the .ear, because it can't find the entitybean classes.
But all needed classes are in this .par and without the jboss-app.xml it works fine.

Can you be really nice and post a simple test case that we can reproduce easily on JIRA?

Thanks
