It sounds as if you are indeed opening/closing connections as you need them.
You need to configure a datasource for your db connections: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html Its fairly easy to set up and the gain is significant. I would say it is probably a good practice to use this anyway, even if you do not expect heavy traffic. --- Geoff Peters <[EMAIL PROTECTED]> wrote: > Andoni - thanks for the advice - someone else just > mentioned the same thing in a reply (Riaan) - > setting the datasource connection pool parameter - > where would this parameter go?
