[Paraview-developers] Facing Problem with Server in ParaView 4.1 Web Version

Hi Seb,

Please reply on the below problem. We are stuck in this.

In Data Prober, when we are not using the Jetty Launcher the data samples
(provided with ParaView) also work fine. But when we are starting it with
Jetty launcher nothing is coming in the left side, but the rendering image
on the right side is coming correctly. We are using 4.1 version.
