when I go to the LoaderRepository which is created for my sar and invoke: java.lang.String displayClassInfo() with a.b.c.d.MyClass (which cannot be found in my application). I get the following output: ### Instance0 found in UCL: org.jboss.mx.loading.UnifiedClassLoader3@14b9b618{ url=file:/opt/jboss/server/default/tmp/deploy/tmp28864my_sar_file.sar ,addedOrder=12} View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4203561#...
