I use clustering for SLSB without any problem, just putting clustering in jboss.xml, so few questions ?
- Have you deployed the jar on the two servers if you don't use farming ?
- If you use farming, look if the application has been deployed well on the two servers
That's all. The first time I had problems, it was because I forgot to deploy on the second server :)
With the 3.0.0 release I was seeing the same problem. If the jar wasn't deployed via the farm it would not round-robin. Failover would continue to work though. Bill Burke is aware of the the problem. It may be fixed in the 3.0.1rc1 source, I haven't had a chance to check it out.
