Currently, I am making sure that each EAR file has its own class loader using <jboss-app> <loader-repository>seam.jboss.org:loader=myear</loader-repository> </jboss-app> I have 15 odd EAR files, all using the same jars. My aim is to reduce the overall memory footprint of jboss. any other options that anyone else knows of ? Also I have observed PermGen exceptions upon constant redeployments of the EARs. I am using JBoss 4.0.4, ejb3-rc8 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3976220#...
