Error launching via VDI-in-a-box on a Linux thin client

Our projects launch fine on Windows workstations but if I try to launch the JNLP using VDI on a thin client (detos) I get the following error.

Any help appreciated.

Can you run Java in general on that box? What do you get if you run:

java -version

java version “1.6.0_26”
Java™ SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot™ Client VM (build 20.1-b02, mixed mode)

Java attempts to launch but throws the permission denied exception.

Thanks for your help.

It sounds like some strange problem with JNLP. I would try using the Linux native launcher instead (available under the Native Client Launchers section of the Gateway home page). This will bypass the entire JNLP system when launching a client or designer. JNLP is a fickle beast, especially on non-Windows systems.
