Hello, I am developing an EJB application in a JBoss application server. Several clients (Swing clients) have to connect to this application to load, modify insert data in a database (using entity and session beans). But I have a problem to solve. When two or more clients are accessing to the same row, one of them can modify this row and, then, the others are working with an out-of-date data of the row (dirty read). ¿It's possible to notify to all connected clients that some row (or rows) have changed? ¿And to update the data of these clients from server? Thank you very much View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024794#...
