[jboss-user] [EJB 3.0] - how to prevent multi-access

Hi, I'm thinking of, let's say when caller A reading data via ejb3, and caller B updates same record, then A wants to update, how can we inform A that the record has just been updated? Can we 1. in ejb xml descriptor file, for somehow specify the transaction level, allowing like non-repeatable read; 2. in coding, for somehow get cachedRowSet 3. using annotation.... Can anyone have idea? Thanks John View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4060850#...
