I have had luck with this, Although it takes a "long" time if you have the IPC portlet (which are actually two portlets) then you have to go though the hassle of removing them from the pages, then removing the instances and THEN removing the war/sar file. I'm not the greatest developer so I'm constantly changing things and this will just add to the overhead. I wonder what happened, in CR3 the "hot undeploy" worked like a charm and i loved it.
