Hi I have a ear with a ejb and a util jar. The util jar contains classes the session bean interface has an parameter which is referenced from the util jar . When i deploy the ejb it complains that it is not able to find the class that was referenced from the jar. EAR lib util.jar - TestParam meta-inf jboss-app.xml application.xml ejbjar Session Bean meta-inf ejb-jar.xml Session Bean ============ package myTransTest; import javax.ejb.Remote; @Remote public interface ITest{ void addPerson(PersonParam personParam); } The PersonParam is being refenced from the util.jar . On deploying am getting a classcast exception saying myUtil.PersonParam not found. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4130345#...
