Hi,
I managed to run a cluster with 2 nodes using:
- Apache (mod_jk) as load balancer
- Tomcat and JBoss in bundle.
All goes very well if I use session context Java beans which replicate their state in
cluster. By the way: GREAT WORK!
The problems arise when I try to use session EJB3 (both stateful and stateless) instead of
Java beans.
I got the following exception
anonymous wrote : javax.ejb.EJBException: Invalid (i.e. remote) invocation of local
interface (null container)
because the proxy uses the remote interface to call the bean.
I've declared bean interfaces as local in components.xml. So the exception.
I think that the problem is load balancing.
If an Ejb client uses its proxy to do balancing it obviously needs to call remote
interfaces.
But when I delegate load balancing to external, when the Tomcat instance is called then
next jboss bean calls should always be local, as declared in components.xml and for
performance reasons.
I'm no able to manage the whole system to do that.
Is it possible? I think so.
I'd like to use Ejb3 for performance reason. I read that that they are more optimized
than pojo bean. Is this still true?
What about the passivation of Java beans? Do they scale well when server load increase?
Passivation is an Ejb feature. I don't know if java beans have passivation too.
Here is my stack trace
