Hi, Following with my application UserEntries I have took out the connection to my DB from the Entity EJB and I leave it alone in a package es.deusto.dbaccessor with my connection class DBConnection.class. My problem is that when I create my ear, it seems as if the application does not find up this class. When I call this class, on the first line of code, the server return me a NullPointerException. I think that I am not building right my ear because when I deploy it on JBoss 4.2.2 GA appears on the console my ejb.jar, my servlet.war, but nothing about dbaccessor-client.jar Thanking in advance, pepelara View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4174827#...
