Hi, I would like to use UserModule into a portlet that allow administrator to create new user. In my portlet I have tested this: UserModule userModule = (UserModule)getPortletContext().getAttribute("UserModule"); User user = userModule.createUser(&#39;toto&#39;,&#39;toto&#39;,&#39;toto(a)test.com&#39;); In descriptor jboss-portlet I have put: | <portlet> | <portlet-name>UserAdminPortlet</portlet-name> | <transaction> | <trans-attribute>Required</trans-attribute> | <transaction> | <portlet> | <service> | <service-name>UserModule</service-name> | <service-class>org.jboss.portal.identity.UserModule</service-class> | <service-ref>:service=Module,type=User</service-ref> | </service> | I have this error: ERROR [UserModuleImpl] Cannot create user toto org.hibernate.HibernateException: Unable to locate current JTA transaction Can somebody tell me if I miss something or if I do something wrong?
