Kabir Khan closed EJBTHREE-69:
------------------------------
Resolution: Done
> Clustered SFSB: load balancing works, failover does not
> -------------------------------------------------------
>
> Key: EJBTHREE-69
> URL: http://jira.jboss.com/jira/browse/EJBTHREE-69
> Project: EJB 3.0
> Type: Bug
> Environment: XP
> JBoss 5.0.0 alpha
> Reporter: Keyur Shah
> Assignee: Kabir Khan
> Fix For: Preview 5
>
>
> Ref: http://jboss.com/index.html?module=bb&op=viewtopic&t=60214
> Consider this simple example:
> [code]
> @Stateful
> @org.jboss.ejb3.remoting.Clustered
> public class SFSBClusterBean implements SFSBCluster, Serializable {
>
> transient String state = null;
> String dto = null;
> transient boolean modified = false;
> public String getState() {
> System.out.println("getState");
> return state;
> }
> public void updateState(String newState) {
> System.out.println("updateState");
> state = newState;
> modified = true;
> }
>
> @PrePassivate public void passivate() {
> System.out.println("passivate");
> dto = state;
> state = null;
> modified = false;
> }
>
> @PostActivate public void activate() {
> System.out.println("activate");
> state = dto;
> dto = null;
> modified = false;
> }
>
> public boolean isModified() {
> System.out.println("isModified");
> return modified;
> }
>
> }
> [/code]
> I have setup a cluster with 2 nodes... When I run multiple clients, it load
> balances well... However, when I shutdown one of the nodes, the clients
> accessing that node also die...
> I built a similar example in EJB 2.1 and it load balances as well as fails
> over correctly.
> One difference I noted was that while the EJB 2.1 bean's isModified() was
> called (and subsequently, ejbPassivate() if the bean was modified) after
> every client method call, the isModified() method is never called for EJB3
> (and so by extension neither is the passivate() method called).
