[jboss-user] [JBoss Portal] - session/transction mandatory when calling UserModule/RoleMod

I only need read only operations like getting list of role, user, etc... I notice that in order for a "MBeanProxy" to works, the call must be done inside a session (ok) but into a transaction too (?) here a working code : | Session session = null; | Transaction t = null; | try { | SessionFactory identitySessionFactory = (SessionFactory) new InitialContext().lookup("java:/portal/IdentitySessionFactory"); | session = identitySessionFactory.openSession(); | t = session.beginTransaction(); | | MBeanServer mbeanServer = MBeanServerLocator.locateJBoss(); | RoleModule roleModule = (RoleModule) MBeanProxy.get(RoleModule.class, | new ObjectName("portal:service=Module,type=Role"), mbeanServer); | | Set s = roleModule.findRoles(); | Iterator it = s.iterator(); | while (it.hasNext()) { | // just dump role for the test | System.out.println("roles : " + it.next()); | } | } catch (Exception ex) { | ex.printStackTrace(); | } finally { | if (t != null) {t.rollback(); } | if (session != null) {session.close();} | } | It's strange to start a transaction and always call a roolback !?! Am I actually making the request right !??? My code will not be call from a protlet, mostly servlet/dwr. anyway adding a trans-attribute to portlet.xml doesn't work for me. | <transaction> | <trans-attribute>Required</trans-attribute> | </transaction> | Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4133226#...
