RE: Problem with SimpleTransform servlet

I created a very simple static method that allows you to pass in the source
XML, transform XSL, and target XML file name and it will do this for you
using Saxon or Xalan (I recommend Saxon..much faster). That be helpful for
you? Then you don't need to create another servlet, you just call the static
transform method from your first servlet.
