Hi, do you use JBoss 5? If yes: "jbossall-client.jar" just defines a bunch of classpath entries in its Manifest.mf, so you have to add much more JARs to your classpath (but I cannot tell you, which ones). And one more thing: as your unit test seems to be a standalone application client, you have to use the REMOTE interface, not the local one (as ALRubinger already told you). Hope this helps Wolfgang View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4221241#...
