Mapscript/Java Tomcat

[Ajay Ranipeta]

Umberto,

Mate you are a legend. All worked like a charm. What actually happend was I
use netBeans for java dev work. And I forgot that i've had a few libraries
lying around there. Combined with a couple of entries in the system env
variables that i didn't really realise.

It all works now, so thanks again.

cheers,
Ajay
