Name and version of the database you are using:

mysql (4.1.11-standard)

------------------
Additional information this is on a tomcat server ( jakarta-tomcat-5.5.7) in a cpanel environment on a linux server. Linux : CentOS 3.4 i686. Using mysql-connector-java-3.0.15-ga-bin.jar.

Sometimes it works fine but at other times it needs "a couple" of refreshes to find a valid connection in order to perform its request.

Does anyone know how to solve this issue?

I see that we're using jdbc2_0-stdext.jar in this application and not for instance mysql-connector-java-3.1.11-bin.jar. Could this cause the problem mentioned above?
