[rules-users] BRMS on Weblogic

Thu Jun 5 11:59:53 EDT 2008

Vikas,

I've always used Sun's JVM; mainly out of habit and one less thing to
investigate if things go wrong. It's worth trying Sun's in this case if
you're using the JRocket JVM.

Can you look at the Seam source code to see what is causing the
NullPointerException at
GWTToSeamAdapter.java line 67? I don't have the source to hand at the
moment. My guess is that there is an issue on the server somewhere (i.e.
some missing or conflicted libs) but have no more detailled wisdom :-(.
