We are running RDS on 2008 R2, using per session virtual IP, and we are unable to run any applications that use Java Web Start (we've tried 3 so far).
The JNLP file downloads and javaws.exe launches to run this, but never gets any further. The process just drops to about 200K of memory and stays inactive.
I have run Wireshark to see what is happening from a network point of view and there is no traffic after the download of the JNLP file. This is in comparison to running from my PC, where javaws downloads the individual files referenced in the JNLP file and then launches javaw.exe to run the code.
I have turned off virtual IP on a test server and this allows things to work as expected, so it is definitely the interaction with virtual IP that is causing the problem. I suspect that the security sandboxing that Java Web Start does is causing it to attempt to use the main IP of the server and that RDS is preventing it from doing so (or something like that).
Has anyone else had the same issue? Any ideas on resolving this?
