Can't see JMX entries in jconsole when using Tomcat JDBC Connection Pool

Question

Hi, we're evaluating switching over from the C3P0 connection pool to the Tomcat JDBC Connection Pool (as described here).

It appears to work as a connection pool but I can't seem to see any JMX entries for it when I run jconsole.
Out of the box C3P0 gives lots of operations and attributes via JMX, the Tomcat JDBC Connection Pool gives none (for me).

According to the page linked above there is a jmxEnabled flag that defaults to true. I've set this explicitly but it seems to make no difference.

What am I missing?

I'm running a fairly standard Java6/Spring/Hibernate app by the way.

Answer 1

Do you see any entries under the tree

Catalina -> DataSource -> javax.sql.DataSource

This lists the number of active connections, idle connections, and a few other common stats. Other then that, what kind of information are you hoping to get out of monitoring?
