Hello,

   I work with a lot of XML, so I am trying to get Spring MVC to
transform it for me.  I have followed the examples in the reference
manual, but I keep getting null pointer exceptions when the view is
resolved.  Could someone be so nice as to cut and paste some code
they've written that is a subclass of the AbstractXsltView?  Thanks.

Also, here is the stack trace I get when the view is resolved.

java.lang.IllegalArgumentException
