Java EE (Java Enterprise Edition) General Discussion

Hello,

I can't seem to get the following to work:

I have the following code:

==========
MyParser.java
==========

package parser;

import org.jdom.input.SAXBuilder;
import org.jdom.Document;

public class MyParser{
  public void startFileParsing(String filename){
    Document document;

    SAXBuilder builder = new SAXBuilder();

    builder.setEntityResolver(new MyEntityResolver());

    try {
      document = builder.build(file);
    } catch (JDOMException e) {
      e.printStacktrace();
    }
  }

  public static void main(String[] args) {
    MyParser mp = new MyParser();
    
    mp.startFileParsing(args[0]);
  }
}

==========
MyEntityResolver.java
==========

package parser;

import org.xml.sax.EntityResolver;
import org.xml.sax.InputSource;

public class MyEntityResolver implements EntityResolver {
  public NTFREntityResolver() {
  }

  public InputSource resolveEntity(String publicId, String systemId) {
    return new InputSource(this.getClass().getClassLoader().getResource("MyDTD.dtd").toString());
  }
}

==========
MyXML.xml
==========

<?xml version='1.0' encoding='ISO-8859-1'?>
<ROOT>
  <ART>
      <AL>H&eacute;</AL>
  </ART>
</ROOT>

==========
MyDTD.dtd (Placed in the bin-directory)
==========

<?xml version="1.0" encoding="UTF-8"?>
...
<!ENTITY % ISOLAT1 SYSTEM "ISOlat1.ent">
%ISOLAT1;

==========
ISOlat1.ent (Placed in the bin-directory)
==========

    <!ENTITY eacute  "&#233;" ><!-- small e, acute accent -->

  at parser.MyParser.startFileParsing(MyParser.java:15)
  at parser.MyParser.main(MyParser.java:24)
Exception in thread "main" 

And when I use MyXML2.xml:

<?xml version='1.0' encoding='ISO-8859-1'?>
<!DOCTYPE MYDT PUBLIC "-//MyDT//DTD MYDTD-XML//MYDTD" "MyDTD.dtd">
<ROOT>
  <ART>
      <AL>H&eacute;</AL>
  </ART>
</ROOT>

Exception in thread "main" 

Can anybody give me some pointers?
