I find the solution. My problme is i'am not decalre the Transaction in my portlet, so i add the description in to the jboss-portlet.xml: -------------------------------------------------------------------------- <portlet-name>UserGestionPortlet</portlet-name> <trans-attribute>Required</trans-attribute> -------------------------------------------------------------------------- Also, i add the service to this file, but i don't kown if it's needed. -------------------------------------------------------------------------- <service-name>UserModule</service-name> <service-class>org.jboss.portal.identity.UserModule</service-class> <service-ref>:service=Module,type=User</service-ref> <service-name>RoleModule</service-name> <service-class>org.jboss.portal.identity.RoleModule</service-class> <service-ref>:service=Module,type=Role</service-ref> -------------------------------------------------------------------------- View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4091876#...
