Eclipse will load most recent version. Which one? You can check in About dialog. Open it by "Help->About Eclipse" then hit hibernate icon. BTW you were using JBT 3.1.0.M3. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/533060#533060] Start a new discussion in JBoss Tools at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
