Hi.
Could you please post a version of server.xml without the comments.
They are very helpful as documentation but make the file extremely
difficult to read. Also, I would check to see if the problem is because
the driver jar could not be found or because of some other problem.

Just for laughs and giggles could you set maxActive to anything other
than zero? A negative number means no limit if that's what you're
after. I'm not sure how zero is evaluated and the javadocs for DBCP's
BasicDataSource aren't 100% clear.

FYI including a path attribute in the default context.xml is pointless,
as that attribute is ignored when a Context is defined
Oddly enough these are probably best explained in the commons-pool
project (http://jakarta.apache.org/commons/pool) which was a spin-off
of DBCP.
maxWait is the maximum amount of time to wait for an object if the pool
is full and there are no more objects (connections) to borrow.

I do check the firewall, yes it was on. It has the option of adding

This probably shouldn't have mattered, since you mentioned that

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
needed when the resource is defined inside the Context... tag and may
