Hi, I'm using a Ubuntu Server to play my JBoss Application Server. in my application( J2EE application ) I use a datasource to a MySQL Database( this database is in another computer ). Well, When I lost connection with this database ( for example, remove the cable of the computer with Database ), I try access my application and JBoss not detected the lost of connection. In my tests with JBoss playing in a Windows XP environment this problem don't occurs, it detects in less one minute. How to resolve this problem ? Where I configure this function ? Thanks !.
