[Paraview] Another ParaViewWeb install question

[Goodwin Lawlor]

Hi,

I've built, installed, and deployed PW - all from git master branch.

The demos PVApp and PVState work well when rendering with javascript, 
java or flash but there's a crash when switching to WebGL.

Were running

tomcat6 (system)
jdk 1.6.0_26
activemq-5.3.2
x86_64 GNU/Linux


WEB_JAVASCRIPT_PATH

points to the source directory ~/PW/WebServer/PWService/web/js/dev

______________________

Chrome on the client side tells me (when switching to WebGL in PWStates):

Uncaught org.paraview.util.ServerDownException
     Paraview.sendEvent
     switchRenderer
     (anonymous function)
     onchange

stepping through the javascript, the  crash
seems to happen at jsonRpcClient.VisualizationsManager.

______________________

Tomcat says (not much)

Start Garbage collecting the ParaView processes:
  - Look at 163841
    -> already quit with error
