[PATCH] VelocityServlet.handleRequest throws Exception

[Christoph Reck]

Please allow the implementation of the abstact method 
VelocityServlet.handleRequest to throw an Exception. It is already
caught in the doRequest(). This way one can return another message 
than the one generated when the returned template is null.

Change the declaration to:
    protected abstract Template handleRequest( Context ctx ) throws Exception;

This should be backward compatible and have no influence on
other implementations.

Thanx,
:) Christoph
