See this wiki http://wiki.jboss.org/wiki/CanJBossTellMeWhenIDontCloseAConnection. Also, you can access the jmx-console at http://localhost:8080/jmx-console and you will find a MBean named "name=MerliaDS,service=ManagedConnectionPool" under the jboss.jca section. Click on that link which will lead you to a page which shows the various attributes of the connection pool. One of them is the InUseConnectionCount. Check out the value of this.
