My impression here is that you had a pre-existing ejb3.0 project (from beta1?) and then upgraded your jboss ide version. There were some underlying changes in the server / runtime stuff between beta1 and beta2, so if you already had an ejb3.0 project linked to a server, that server is probably missing data and needs to be re-created. Then the EJB3.0 project needs to re-link to that server. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3980419#...
