    Shankar Khanna Newbie

      Hi,

      I am not able to get childeren of a portal node. I am getting this exception ( org.hibernate.HibernateException: Unable to locate current JTA transaction
      )

      Here is my code:

      protected void doView(JBossRenderRequest req, JBossRenderResponse res) throws PortletException, PortletSecurityException, IOException {
      
       res.setContentType("text/html");
       PortalNode portalNode = req.getPortalNode();
      
       Locale locale = req.getLocale();
       if (locale == null)
       locale = Locale.getDefault();
      
       while (portalNode.getType() != PortalNode.TYPE_PORTAL)
       {
       portalNode = portalNode.getParent();
       System.out.println(portalNode.getDisplayName(locale));
       System.out.println(portalNode.getName());
       System.out.println(portalNode.getType());
       }
      
       Iterator childrenIt = portalNode.getChildren().iterator();
      
       while (childrenIt.hasNext())
       {
       PortalNode child = (PortalNode)childrenIt.next();
       System.out.println(child.getDisplayName(locale));
       }
       }



      Code does not work at this line:

      Iterator childrenIt = portalNode.getChildren().iterator();



      This is an exception that i am facing
