[jboss-user] [JBoss Portal] - Unable to itrate through portal nodes

[shankarkhanna]

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
