Hi, I would suggest IFrames. Why it doesn't meet the requirements? In the portlet swap I used the portlet IFrames Jboss offers to open an app I have inside of a portlet (I only had the URL as well). It worked very well... You could try using web services too, but that would only bring you the app data not the URL, and this is all you have right? --Mariella.
