Hi, <br>
I am following the paraview web guide and testing the provided web application in version 4.4.0 .<br>
I modified the script in <br>
<a href="http://www.paraview.org/gitweb?p=ParaViewSuperbuild.git;a=blob_plain;f=Scripts/pvw-setup.py;hb=HEAD" target="_blank">http://www.paraview.org/gitweb?p=ParaViewSuperbuild.git;a=blob_plain;f=Scripts/pvw-setup.py;hb=HEAD</a>
<br>
in order to download Paraview4.4 for linux 64 (I am running Ubuntu 15 desktop in a virtual machine), change the ports . I am following the documentation in
<a href="http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#" target="_blank">
http://www.paraview.org/ParaView3/Doc/Nightly/www/js-doc/index.html#</a> , and for a start I am trying the Python launcher.
<br>
<br>
Using the script bin/start.sh I am able to load the webpage at <a href="http://localhost:4400/apps/LiveArticles/" target="_blank">http://localhost:4400/apps/LiveArticles/</a> , but when I click to embedded visualization , I see that the "server" process is starting a vtk render window but without data . After a moment the visualization
on the web page closes. <br>
<br>
Here are the relevant part of the logs :<br>
<br>

Interestingly I've seen that the process that is called by the PythonLauncher is <br>
<font face="Courier New">/data/pvweb/ParaView-4.4.0-Qt4-Linux-64bit/lib/paraview-4.4/pvpython /data/pvweb/ParaView-4.4.0-Qt4-Linux-64bit/lib/paraview-4.4/site-packages//paraview/web/pv_web_file_loader.py --port 9442 --data-dir /data/pvweb/data -f</font><br>
<br>
I've already tried to modify the javascript in the embed.html code in order to "force" the data file in the command that the server uses to launch the script, but the problem of the render window immediately closing remains.<br>
I don't think it's a problem of the configuration, because I am able to use the visualization app and load some data.
<br>
<br>
Any suggestion about this problem? I don't know how to debug further to understand if the problem in on the javascript or python side<br>
<br>
Best regards<br>
Livia <br>
