Tomcat Session Replication + Spring bean

I have a Spring bean which will be used for storing user details or any other relevant information. I store this bean on the session level.

<bean id="userSession" class="com.test.SessionImpl" scope="session">
<aop:scoped-proxy/>
</bean>

Now I have few server and I would like to build Cluster with session replication using SimpleTcpCluster.

When I'm updating the bean on one of the cluster node will it be replicated to other nodes? I have a concern regarding that because this bean resides on sesison level, but not in the session itself. Correct me if I'm wrong.

As long as Tomcat can replicate the object (ie, the object is serializable) then the bean will be replicated. It is stored as an attribute on the session -- you can verify this either in your debugger or by iterating over the attributes of the session in your code.

The spring docs (http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/beans.html#beans-factory-scopes-session) imply this is the case but are not explicit about the exact mechanics.
