Hi Daniel,
Which version of Apache are you running?
Did you enabled all the modules?
$ sudo a2enmod vhost_alias
$ sudo a2enmod proxy
$ sudo a2enmod proxy_http
$ sudo a2enmod proxy_wstunnel
$ sudo a2enmod rewrite
For the launcher configuration, do you have a proper
"resources" and "apps" section?
I'm guessing you are looking at the following documentation
pages?
-
https://kitware.github.io/paraviewweb/docs/guides/apache_front_end.html
<https://kitware.github.io/paraviewweb/docs/guides/apache_front_end.html>
-
https://kitware.github.io/paraviewweb/docs/guides/python_launcher.html
<https://kitware.github.io/paraviewweb/docs/guides/python_launcher.html>
Once you have the forwarding of the launcher request
working, the next part will be the forwarding of the ws.
But we can talk about it when and if you run into issue
about it.

Hi Daniel,
I want to use paraview web with SSL. As far as I
understand I need apache as a proxy server for
that? Or is it possible with pvpython?
It might be possible with pvpython, but I've never
done it, I've always used apache to rely on a single
opened port and handle the encryption.
I have my own launcher which opens pvpython with a
different port for each user. Is this the right
way? Will this work with ssl?
If pvpython directly support the wss connection, you
can be good. Usually the setup, that I do is that I
have Apache serving only the port 443 (https) for both
the static content and the (wss) websocket endpoint.
And I use a mapping file between the Websocket
endpoint that get returned by my launcher and the
host/port I should connect to on the backend to
establish the link between the client and the actual
ParaViewWeb server instance.
But that does not mean, that's the only way to do it
and if you don't mind having several port open, I
don't see why it could not work.
Concerning:
https://kitware.github.io/visualizer/docs/
<https://kitware.github.io/visualizer/docs/> The
web visuailzer should work via npm installation?
It does not work for me:
C:\Users\danie\AppData\Roaming\npm\node_modules\pvw-visualizer\bin\pvw-visualizer-cli.js:41
var pvPythonExecs =
find(paraview).filter(function(file) { return
file.match(/pvpython$/) ||
file.match(/pvpython.exe$/); });
^ TypeError: find(...).filter is
not a function at Object.<anonymous>
(C:\Users\danie\AppData\Roaming\npm\node_modules\pvw-visualizer\bin\pvw-visualizer-cli.js:41:36)
at Module._compile (module.js:409:26) at
Object.Module._extensions..js (module.js:416:10)
at Module.load (module.js:343:32) at
Function.Module._load (module.js:300:12) at
Function.Module.runMain (module.js:441:10) at
startup (node.js:139:18) at node.js:968:3
Well, I guess I haven't tried to run the new
Visualizer server on a Windows machine.
But with ParaView 5.2 (yet to be released), we should
have a ParaViewWeb back in the binaries. So we should
make sure our Visualizer command line tool work on
that platform as well.
Although, the command line is more for beginners than
anything else as it only simplify the demo usage. In
real word deployment, with a launcher, the true
pvpython command line should be used instead.
Here is an example of what you should see in a working
environment:
$ Visualizer -d ~/Downloads/
===============================================================================
| Execute:
| $ /Applications/paraview.app/Contents/bin/pvpython
| -dr
|
/Users/seb/Documents/code/Web2/visualizer/server/pvw-visualizer.py
| --content
| /Users/seb/Documents/code/Web2/visualizer/dist
| --port
| 8080
| --data
| /Users/seb/Downloads/
