Is there a way I can check the status of the connection pool using JNDI?
I'm working on a web application using Tomcat and SQL Server with the JTDS driver and I'm having concerns that I may have some stray connections open or some performance issues that I want to tweak. I'd like to make a JSP/Servlet that I can get the health information (active connections, open connections etc) about the connection pool at any given time.
Some pools or J2EE containers have the functionality built-in. Sometimes it is a config setting on the pool. Sometimes it is a JMX component exposing the runtime state of some kind of pool manager. I'd start by checking the documentation, admin gui, and any javadoc for stuff that sounds JMX-ish.
