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.  
Thank you

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

```auto
java -version
```

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.
