But, it's the JARStructure not the FileStructure that recognises it. That's because in JBoss5 we don't require you have the correct extension for top level deployments. We look at the structure instead. In this case, there is a META-INF sub-folder so it is a jar. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4107345#...
