The issue here is WebappClassLoader.toURLs() returning a lot of data that gets added to the RMI streams as "annotations". We don't want this, so this either needs to be fixed by * returning | @Override | public URL[] getURLs() | { | return new URL[0]; // Optimize away the Memory Allocation | } | in JBoss's subclass org.jboss.web.tomcat.service.WebAppClassLoader * Making Tomcat use JBoss's classloader directly, i.e. no Tomcat WebappClassLoader at all View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4173082#...
