I don't know maybe it is too late but I can't seem to come up with 
anything better than this.  What I need to do is take a String that 
contains the name of a file in my program's JAR file, a URL for a 
network site or the name of a file on the accessible file system and 
turn it into a URI.  I want to check in that order, in the JAR file, a 
file on the filesystem or a network reachable URL.  Even this has some 
holes and it is really ugly.  Thanks...

             URI uri = null;
             URL url = getClass().getResource(fname);
             if (url == null) {
                 try {
                     url = new URL(fname);
                 } catch (MalformedURLException murle) {
                     uri = new File(fname).toURI();
                 }
             }
             if (uri == null) {
                 try {
                     uri = url.toURI();
                 } catch (URISyntaxException urise) {
                     urise.printStackTrace();
                 }
             }

             if (uri != null)
                  // do something with the URI
