[jboss-user] [JBoss Portal] - Servlet calling java:portal/UserModule

Hi there, i have one portal running on Jboss and one is the servlet. In my servlet, i will required to call the usertable in JBP_USer to verify the user registered already or not? Thus, below is part of the coding... try { UserModule userModule = (UserModule) new InitialContext().lookup("java:portal/UserModule"); User temp_user = userModule.findUserByUserName(username); authenticateUser = temp_user.validatePassword(password); } catch (Exception e) I have not problem on loading the JNDI UserModule. But once i call the findUserByUseName(), i was thrown an error: org.hibernate.HibernateException: Unable to locate current JTA transaction at org.hibernate.context.JTASessionContext.currentSession(JTASessionContext.java:61) at org.hibernate.impl.SessionFactoryImpl.getCurrentSession(SessionFactoryImpl.java:544) at org.jboss.portal.identity.db.HibernateUserModuleImpl.getCurrentSession(HibernateUserModuleImpl.java:298) at org.jboss.portal.identity.db.HibernateUserModuleImpl.findUserByUserName(HibernateUserModuleImpl.java:90) at my.mimos.servlet.ProfileSendServlet.doGet(ProfileSendServlet.java:96) SO, basically if i understand correctly, it's pointing to me can not load the user transaction. Can you help me or suggest any solution to me? thank you View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4138238#...
