Examples of SPRING+HIBERNATE+JTA distributed transactions

For distributed transactions that span multiple hibernate sessionfacotry, simply combine the definition of Jtatransactionmanager with multiple Localsessionfactorybean as a transaction strategy. Each of your DAO gets its own sessionfactory references through the bean properties. If all of the underlying JDBC data sources are containers that support transactions, as long as the business object uses Jtatransactionmanager as a transaction policy, it can divide the transaction across multiple DAO and multiple session factories without any special processing required.
