A few questions to this:

1. What Java (JVM) do you use in your deployment?
2. Have you any specific configuration related to SSL certificates
3. Have you uploaded your own certificate or you use self-signed and Tigase auto-generated certificate?

1 openjdk6 with FreeBSD 8.2 portage system (default one)
2 I configured automatically with tigase installer.. I did not do anything
special
3 I think its tigase auto generated certificate.. with client i can register with psi and gajim but not see each other...

what can be the problem?

Ok fixed the problem...

What was the problem or actually what was the fix?
