EntityResolver Problems

[Sean McCauliff]

I want to package some schemas into a jar file to avoid having the user 
need to have a magic directory that they point to that contains the 
schemas.   So I implemented an EntityResolver, but I am still getting 
errors.  The XML file that I am reading contains references to the
following schemas:  XMLSchema.xsd,  xhtml1-strict.xsd and iface2.xsd  Is 
there something that I am doing wrong? Is this a bug?

Xerces-J 2 Version: 2.1.0
JDK  1.4.1 RC1
Thanks,

class MyEntityResolver extends DefaultHandler {
   public InputSource resolveEntity(String publicId, String systemId) 
throws SAXException {
       System.out.println("---->resolveEntity:" + publicId + " " + 
systemId);
       if (systemId == null) return super.resolveEntity(publicId, 
systemId);
       String orig_sys_id = systemId;
      
       //extract the real entity name / is ok because it is a url
       int i = systemId.lastIndexOf('/');
       if (i != -1 && systemId.length() != i) {
           systemId = systemId.substring(i+1,systemId.length());
       }
      
       System.out.println("----> new sys id is " + systemId);
      
       try {
           URL url = getClass().getResource("/"+systemId);
         
           if (url == null)  {
               System.out.println("----> Still nothing.");
               return super.resolveEntity(publicId,orig_sys_id);
           }
          
           System.out.println("----> found resource " + url.toString());
           InputStream is = url.openStream();
         
           System.out.println("----> input stream is " + is);
           //new Exception().printStackTrace();
           return new InputSource(is);

       } catch (IOException ioe) {
           System.out.println("Having trouble finding " + systemId +
               ", probably a CLASSPATH problem.");
           return super.resolveEntity(publicId, orig_sys_id);
       }
   }
   }
