To start a new topic,
Your not providing a lot of context here, so we can only guess. The
error implies the pool is exhausted. Can you provide details on the
pool config and when/where this error occurs? Additionally, you might
want to check out the DBCP website at http://jakarta.apache.org/commons/dbcp

Trawick,
I do check the firewall, yes it was on. It has the option of adding
exceptions to allow programs/service to connect to the machine. So I
added SQL server 2000 on port 1433.
This probably shouldn't have mattered, since you mentioned that
everything is running on the local machine.

Is your SQL JDBC driver in common/lib? It has to be there for tomcat to
set it up as a resource.
Also drop the ResourceLink.../ tag from your context definition. Not
