please tell or give some links on how to synchronize data in cluster of JBosses. For example I have the same SLSB running on two different nodes in cluster. This SLSB gets some Entity Bean presenting table in database (MySQL 5.0.24a) and increases some of it's fields. What should I do to make updates from both nodes saved in database? Mentioned SLSB method is annotaded with @TransactionAttribute(REQUIRES_NEW).
