WebLogic HTTPSession Replication problem

           Summary: WebLogic HTTPSession Replication problem
           Product: Struts
           Version: 1.0 Final
          Platform: Other
        OS/Version: AIX
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: Controller
        AssignedTo: struts-dev@jakarta.apache.org
        ReportedBy: john.dcosta@verizonwireless.com


We have a WebLogic clustered environment for our application.  We are using 
WebLogic HTTP Session replication.  We are running into problem in one of the 
Struts class "RequestProcessor.java".  Once this starts happening our managed 
server get hosed.  Just a side note, we are also using Tiles in the 
application. You may have to address that issue too along with this.

Note:
All class in the HttpSession needs to be serializable in order for weblogic 
httpsession replication to work.

Can you please address this issue if possible.
