Patrick,
I've been toggling the dynamic help and looking at the logs (apache and midas/log/dev.log). Here is what I am getting without and with dynamic help turned on
Dynamic help off:

Brian,
Are you able to get to the admin page and disable dynamic help?
That should yield an improved error message.

Hi Zach, et al.,
I'm making progress here. I looked at Sebastien's suggestion of using VirtualGL but decided to go back and build a VM with X11 support. I've got Midas running and ParaView web configured as per the web site and Zach's instructions. When I got to view an object (a 3D CT stored in .mha format) I get a blank canvas with "Volume rendering: pe0017s4.mha" on the top and a bunch of control widgets on the right.
When I look at the apache2 logs I see the following.

Hi Brian,
Answered your questions inline.

Patrick,
That saved a lot of time! A couple of dummy questions. In /var/www/midas/modules there is already a pvw directory. So where am I supposed to create the symbolic link to $PARAVIEW_ROOT/lib/paraview-4.0/www?
You should create a symlink at /var/www/midas/modules/pvw/public/import, and it should point to the paraview-4.0/www dir.
Also, just because I'm kind of dense, do I need to set the DISPLAY environment variable. The pop-up help says "If the DISPLAY env var should be set…" I don't know if it should be.
It depends what environment you are running in. If you plan on running this headlessly as a server, you will probably need to set the environment variable. If you are running the server within an already existing X environment, you probably won't need to set it. If you open a terminal and type
echo $DISPLAY
It will show you the current value of your display ID.
Finally, is there a tutorial or demo for the Midas/ParaView interface?
We just finished transitioning the demo application to the latest version of ParaViewWeb. The demo of the old capabilities is here: http://50.58.123.185/external/midas/visualize/paraview/volume?itemId=44
There isn't much currently in the way of developer-oriented documentation for the module; for that you might have to just consult us with your questions :)
Thanks,
Thanks for the help.
Brian

Brian,
You'll need to build Paraview Web from Source or download binaries. It comes with paraview, so you should be able to follow the instructions stemming from this wiki page:

Hello Midas World,
I'm trying to build an instance of Midas with ParaviewWeb enabled. I'm working on an Ubuntu 12.04 instance. Midas built fine, but I'm having a difficult time getting Paraview to build. Just curious if the paraview-python package that is available in the ubuntu distribution is sufficient for this purpose? If it is, curious about the details of the configuration for the instructions: "Make sure to symlink the www directory of your ParView build directory…"
I'm suspicious of the package since when I try to run pvpython I get an error:
"Error converting executable file "/usr/bin/../lib/paraview/pvpython" to real path: no such file or directory"
