Resolving Entities

• The EntityResolver allows you to substitute your own URI lookup scheme for external entities

• Especially useful for entities that use URL and URI schemes not supported by Java's protocol handlers; e.g. jdbc: or isbn:

• The EntityResolver interface:

  package org.xml.sax;
  
  import java.io.IOException;
  
  public interface EntityResolver {  
  
    public InputSource resolveEntity (String publicId,
     String systemId) throws SAXException, IOException;
      
  }
