Accessing Liferay User object for logged-in user

[Shantanu Puranik]

Hello Rich,
I've recently started working on Vaadin(6.6.4) based portlets on Liferay (6.0.6) using Tomcat.
Does your new book includes contents realted to Vaadin based portlets?

As of now I'm facing trouble in accessing Liferay User object for logged-in user.
My application class implements PortletRequestListener and PortletListener interfaces.
Corresponding methods implemented has following code:

User user = null;
String remoteUser = "";

try 
{
	user = PortalUtil.getUser(request);
	setUser(user);// setter in vaadin Application
	if (request.getRemoteUser() != null)
		remoteUser = request.getRemoteUser();
	
} 
catch (PortalException pe) 
{				
	pe.printStackTrace();
}
catch (SystemException se) 
{
	se.printStackTrace();
}

This code is not working at my end.
Any clue on this?

You might want to try getting the User out of the ThemeDisplay or ServiceContext objects instead. That always works for me.
