Hi Adrian, It worked fine using the basic version of spring jar instead of velocity-dep. I only removed the velocity-dep and added the velocity basic jar and Jakarta Commons Lang jar.
Thanks for your help.

The purpose of velocity-dep is to be easy to use Velocity without importing many jar files. It is not a good idea to use velocity + dep version in a complex environment. Use velocity-1.5.jar and include mandatory and/or optional libraries as per http://velocity.apache.org/engine/releases/velocity-1.5/jar-dependencies.htm l. If you don't want to escape references(see developer manual) don't include Jakarta ORO(even if is mandatory). PS. Maybe Jakarta ORO should be marked as optional because by default is not used(searching for EscapeHtmlReference doesn't show any usage).
