Hi Seb,
I thought I'd go ahead and try to install PWServer. I'm running on OS X
10.7 from the paraview and paraviewweb git hub sources updated yesterday.
I'm using activemq-cpp-library-3.4.0. The paraview build passed all it's
test and pwserver built with no complaints. I get the fulling when testing.
Any idea where to look for the problem? Thanks,Chris
