Re: Communication failure during handshake. Is there a server running on localhost:3306?

If I had to venture a guess based on this information, it would be that you have an _old_ version of the JDBC driver laying around in your CLASSPATH (jre/lib/ext, WEB-INF/lib, $CLASSPATH, etc), and _that's_ the one your webapp is using.

When you use your standalone program, it's using the driver version you expect (3.0.16).

Pre-3.0.x or early 3.0.x drivers can't connect to MySQL-4.1.3 or newer, because the authentication protocol changed starting with MySQL-4.1.3.
