Hello Gajendra,
You will find Stacy's work directly in the CVS tree (or last source daily snapshot
available from JBoss web site).
As for the HA features for SLSB, you will get everything needed here :

Hello Dennis,
For now, for entity beans, we use pessimistic locking at the database level i.e. we
use the ~"SELECT ... FOR UPDATE" features of databases to lock database rows.

I know this is OT, but the thread reminded me of this...
Has anyone looked at using something like "JSR-107: JCACHE - Java
Temporary Caching API" to help in keeping cached entity beans in a
cluster synchronized instead of relying solely on the database?

A first test release of HA features for JBoss is available from here:

I will shortly (I do not have much time these days) post a written proposal
for the next version

If you can't wait, simply checkout JGroups from CVS, do a build.sh
