The cause is : In fact I use Hibernate 3 instead of Hibernate 4 and I forget to add <property name=+"jboss.as.jpa.providerModule"+ value=+"org.hibernate:3"+ /> into my persistence.xml. So after adding this property everything goes well. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/763526#763526] Start a new discussion in JBoss AS 7 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
