[omniORB] Callback objects not working with corba server on vmware

[Michael Thaler]

Hello,

I have written a Java application that connects to a satellite telemetry 
processing application (SCOS 2000) which uses Omniorb. My application can 
connect to the telemetry processing application, register parameters and 
receive updates. Unfortunately after a day or so my application stops getting 
updates because there is an exception on the server: exception when notifying 
the client:IDL:omg.org/CORBA/TRANSIENT:1.0.

I am trying to debug this problem. For debugging I want to run the telemetry 
processing application as a VMWare image on my computer. My computer (the host) 
runs Windows Vista, the telemetry processing application is running under Suse 
Linux Enterprice Server 10 (the guest). I set up host-only networking and added 
the hostnames to /etc/hosts and c:\WINDOWS\System32\drivers\etc\hosts. I can 
ping from the host to the guest using both IPs and names and I can also ping 
from the guest to the host using IPs and names.

My application can connect to the telemetry processing application and register 
parameters, but as soon as the telemetry processing application calls my 
callback object it throws a corba.transient.exception: Exception when notifying 
the client:IDL:omg.org/CORBA/TRANSIENT:1.0". I tried to turn off the Windows 
Vista firewall but this did not solve the problem either. Running the VMWare 
image under Windows XP or Debian works just fine. My application can connect, 
register parameters and gets updates (the server can call the callback object). 
Thus this seems to be a Windows Vista issue. Unfortunately I have to use 
Windows Vista at work. Does anybody have an idea what could be wrong?

Greetings,
Michael
