> Hi!
>
> I'm using the ConnectionPool example from Jason Hunter's book with my
> servlets and a mySQL database on Linux...
>
> Whenever a query hits the database, it's creating a new connection (it's
> never reusing a connection from the pool)...
>
> I don't really know the best way to troubleshoot this...
>
<VR> Open a log file in each of your classes (ConnectionPool,
YourServletApp)
and write messages to the log file to show the flow of control
and variable values.
</VR>
> The first thing I tried was changing the setup on the ConnectionPool class
> to perform a simple query I know is valid to perform the check on the
> Connection object...
>
> mySQL doesn't support transactions so I didn't know if
> con.setAutoCommit(true) would throw an exception (and thus create a new
> connection) or not...
>
<VR> Write a test program to find out if setAutoCommit throws
exceptions.
</VR>
> It's still creating a new connection every time so I end up with a VERY
> large pool that maxes out the DB...
>
> Any suggestions?
