[ice-dev] Questions about ICE-ParaView integration
Sebastien/Scott,

I can't seem to reproduce the previous error any more. However, I have encountered an entirely different problem.

First, I start off the http_pvw_server.py on a remote server (I'll call it someserver).

jordan@someserver ~/dev/x86_64/paraview/4.3.1 > bin/pvpython /path/to/http_pvw_server.py --host someserver --port 61000

I get the following message and an X window with the 6-sided cone:

Xlib: extension "NV-GLX" missing on display "localhost:12.0"

On my workstation, I kick off SwingExample.java from Eclipse. The X window gets approximately twice as big, while the Java client shows a black screen (image attached).

If I click on the window, I get all kinds of fun output from both the Eclipse console and the server. Those are also both attached.

My question is: am I launching the server correctly?
If so, any idea what could be the problem here?

Thanks,
Jordan

Jordan,

Patrick and Sebastien are our colleagues at Kitware. I have CCed them and the dev list.

Jay/Alex,

I am currently experiencing a problem running the ParaViewWeb demo. Who is the primary POC for ParaView integration? (Also, feel free to CC this to the ice-dev list if you think that would be best.)

After much trial and error navigating available ports on our main dev server, I have figured out how to run the simple server Sebastian (?) wrote. But at the moment I get a FileNotFoundException on the Java client side.
