Can someone tell me how to build, and successfully use, the portlet-api
branch version of jetspeed? I've checked it out from CVS, built it, and
copied it to the tomcat directory. When I try to open the first page, I get
a null pointer exception (see message below). I've duplicated the steps
using the 1.3a1 gold release and it seems to work fine. Any ideas would be
greatly appreciated. I should mention that we are intending to evaluate
IBM's Webphere Portal Server, so the common portlet API is pretty important
to us.
thanks
Rich
