I recently migrated my application from jboss 2.4.8 to 3.2.1 application seem to work fine underneth its causes trouble for database. I have this datasource connecting to DB2 on as/400. If i leave application alone with out activity. datasource works fine it does destroys pool every 15 to 22 minutes as idle-timeout is set to 15 minutes and recreates it. But what my problem is when activity on application it didn't used pooled connections it created new connections instead. this seems bizaare.... help me out with this.
