Well, something like this (written out of memory and untested). Extremely 
simple, but should give you the basic idea. To be used only when you
know that the href argument will be a relative url:

     public class MyUriResolver implements URIResolver {
         public Source resolve(String href, String base)
             throws TransformerException
         {
             String ref = "file:" + System.getProperty("basedir") + "/" + href;
             return new StreamSource(ref);
         }
     }

and then

    Transformer t = ...;
    t.setURIResolver(new MyUriResolver());
    t.transform(.....);

/pmn
