yes, thanks to ha-jndi.

well, I suggest you take a look at the clustering documentation. You will
have to either use commit option B/C to go to the database each time (and
use pessimistic locking at the db level i.e. select for update trick i.e.
<row-locking> tag) or use a cache invalidation framework. Distributed cache
will come in 4.0.
