You should create a symlink at /var/www/midas/modules/pvw/public/import,
and it should point to the paraview-4.0/www dir.

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.

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,
