Can't Get Stateful Session Bean Replication Working
I have a clustering setup with two JBoss 4.0.3RC1 nodes, one running in solaris 10 and the other in Win XP. I have laso Apache2 + mod_jk1.2 for load balancing but without HTTP session replication implemented. The stateful session bean is coded with @clustered annotation and its function merely keeps a counter on the number of times it is acessed and has a method to return the counter. A JSP calls the session bean method locally to get the counter. Starting the JSP on a browser and each time making a call to session bean increments the counter correctly. When I shut down one of the server, Apache2 correctly perform the load balancing by redirectiing to the running server. However, the counter is not saved and starts from 1 again.
I presume, when the request goes to the other sever, another JSP is call which invoke a new session bean. If I want to maintain the existing configuration (two servers with JBoss AS each, web server with Apache2), what needs to be done to implement a Stateful Session Bean Replication?
The console shows that the clustering is implemented when the ear file was deployed in the fram folder.
