Hi,

I have a seam web application(war project) with one session scoped bean:

@Name("crudAction")
@Scope(ScopeType.SESSION)
public class CrudActionBean implements Serializable{
     private String msg; //with getter and setter methods
      public String crudAction(){
           msg= "Content to be displayed on crudAction page after this action"; // this will be displyed in <h:outputText../> on crudAction page.
      return "/crudAction.xhtml";
      }
}

web.xml has <distributable/> tag defined.
components.xml has distributable="true" defined in <core:init.../> tag.
I am using Seam 2.2, Jboss 5.1 server and JDK 1.6 and Windows XP OS.

After killing jboss of node1, if I try to reload page or do some action, I get following error message on jboss console of node2:

And does not replicate session.

ClassNotFoundException occurred unmarshalling value java.lang.ClassNotFoundException: org.domain.seamdemo.session.CrudAction

Detailed stack trace has been attached here with this post.

But replication works successfully, if I try above by creating Ear project and modifying the bean to SFSB like:

@Stateful
@Name("crudAction")
@Scope(ScopeType.SESSION)
@Clustered
public class CrudActionBean implements CrudAction,Serializable{ "same code as above"} //CrudAction is @Local interface.

The value of msg variable were displyed even after realoding page.
Can someone please help me for the above.
Let me know if additional information is needed.

Thanks.
