RE: HttpSession Replication in Tomcat Cluster not working with EJ B's!
Filip,
You were right. It's works with the handle. Thanx for all the co-operation.

I think you need to store the EJBHandle, not the actual bean that you are
referencing.
is that what you are doing?

Andy,
I agree with your point about a SFSB being an extension of a client. But
then, if I store the 'state' alone in the httpsession and update the state
by using a new SFSB everytime, the whole concept of SFSB's are lost. I would
rather use a stateless session bean and use httpsession for persisting my
conversational state. (I know this line of thinking against use of SFSB has
been advocated many a times and is a different discussion altogether)
I beleive what ur suggesting to be a workaround and is not an acceptable
solution. My design requirement requires a SFSB and I need servlets to
invoke my SFSB. I will also need to cluster the TC5 servers. Passing the
reference within the servlet and between method calls is the only way to
hold a handle and interact with a single instance of a SFSB.
If I use a JBOSS 3.2.3 server which comes bundled with TC then JBOSS takes
care of my httpSession sharing between the various JBOSS servers in the
cluster. (JBOSS has a different mechanism for httpSession sharing). But I
would like to have a multitier cluster with seperate TC clusters and
seperate JBOSS clusters. So the end question would be if TC 5.0.18 has the
capability to handle such a scenario or not.

Think of a stateful session bean as an extension of the client. By
storing the remote reference inside your session, you are attempting to
persist your "Client extension" across 2 different clients (2 different
tomcat instances). I don't think this is a sensible idea, and I'm not
sure it's even allowed.
I would advise you not to store remote references inside your session
objects. Try storing just the current 'state' inside the session. Use a
ServiceLocator to get an instance of the session bean each time you need
it, using the current session to populate the state. This may work
better for you.
Regards,
Andy

Subject: HttpSession Replication in Tomcat Cluster not working with
EJB's!
Hi everybody,
I am trying to cluster Tomcat Servers ver 5.0.18 (Two servers) and my
application servlets are accessing Stateful session beans. Typically,
the first invocation of the servlet gets the Remote of the SFSB and
stores it into the session. The other Tomcat's in the cluster throw up
an error "ClassNotFoundException while loading persisted sessions". I
have the same war file deployed in all the Tomcats and the Tomcats in
turn talk to the same app server (JBOSS 3.2.3). I am attaching my
configuration and log outputs of both the servers. Would like to know if
this is a bug/limitation or is there a solution to it.
Cheers
Suraj
