I have a complex application that includes 2 ears and a war, heavy use of dto's and backing beans. It works fine on 4.0.3SP1, but on any other version I've tried (I've just been trying 4.2.1) I am between a rock and a hard place with classnotfound and classcast exceptions. Is there a way to make the classloading in 4.2.1 behave just like 4.0.3SP1 ? Thanks Gerry View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4077285#...
