Hi everybody,
I'm trying to use Clustering but I'm running into some problems. I use jboss-3.0.3 with tomcat-4.1.12 and the default configuration for clistering and farming. I'm using HA-JNDI as well.
What I'm doing:
Just after I call the create() of my EJB (Stateless Session EJB), I start several threads, each one calling once the remote method of the EJB. I mean: 1 call to create() then several calls to remoteMethod() in separate threads.
The problem is:
When I do it from a standalone Java client for the EJB, it works fine and I can see the RoundRobin. But when I do it from a Servlet, only one JBoss server is called (the same that runs the Servlet), that is, the cluster doesn't work properly.
Any idea why??? Is there a solution for this? (I can't use a standalone client)
I'm sending some source code below...
Thanks in advance!
Regards,
Paulo
