Logged In: NO
This exception is caused by the fact that mail.jar was left out
of the .war. Once Tomcat expands the war into a directory
structure, drop the mail.jar (you can get it from Sun's
website) into the same directory where the activation.jar is
located (WEB-INF/lib/). Restart Tomcat and you're golden.
