[jboss-user] [Clustering/JBoss] - JBoss Clustering + Windows NLB (Network Load Balancing) = Ba

[evk]

Hi, 

I recently tried setting up 3 machines in a JBoss cluster that were ALSO in a Windows Network Load Balancing (NLB) cluster. I attempted this because I figured NLB would give me a virtual IP address that I can use to load balance HTTP requests to members of the JBoss cluster (serving out functionality via stateless session beans and web services)

This seems to have failed miserably; Jboss locks up on startup and exhibits other strange behavior until I turn off NLB.

Is this Not A Good Idea or otherwise Officially Not Supported? 

If all I want is HTTP load balancing for fault tolerance (high availability), is a hardware load balancer probably my best option? I tried mod_jk and it seems ok, but now the machine running Apache represents the single point of failure.
