I definitely want to install ParaViewWeb as server that is accessible to others so that others in my team need not build their own instance. I will change all Paraview bin contents to be owned by tomcat user. I will rebuild the application and test the pvpython. I will let you know how it goes
Thanks
Chandrika

That's not good to set ParaView code to belong to root. They should belong to tomcat6 as they are going to be called by tomcat.
Anyway, I should have asked it before.
Are you installing ParaViewWeb as a server that is meant to be accessible from the outside or just to test out the application ?
If it is the later, you should simply install it under your user. It will be way easier as you won't have permission issue or mesa/server x issue.
Otherwise, it seems that your ParaView installation is not right. For some reason Try to rebuild the application as the proper user. And make sure pvpython is working.

I am not able to remember the exact error message - disappeared so I assumed that ParaViewWeb is now able to detect OSMesa. Should I have run some clean command before doing a configure, make and make install ?
