Re: Still have problems validating xml file with xsd schema

[Marcus Schneller]

Hi Paul,
your ansewer came very fast. Thank you!
Actually I tried that with the MyResolver class:
here is the code:
import org.xml.sax.EntityResolver;
import org.xml.sax.InputSource;
import java.io.FileReader;
import java.io.FileNotFoundException;
public class MyResolver implements EntityResolver{
 
  private FileReader schema;
 
  public InputSource resolveEntity (String publicId, String systemId)
  {
    System.out.println("Hello");
    if (publicId.equals("http://www.zhwin.ch/schnemac/Req";) || 
systemId.equals("ReqSchema.xsd")) {    
      try{
       schema = new FileReader("F:/ZHW/test/ReqSchema.xsd");
      }
      catch(FileNotFoundException f){
           System.out.println(f.getMessage());
      }
    }
    return new InputSource(schema);
  }
}

In the class were the parser is, I created a new objekt of the MyResolver:
   private DocProcessor processor;
   private SAXParser parser;
   private MyResolver resolver;
  
   public InputDocumentHandler() {
    
       try{
           processor = new DocProcessor();
           resolver = new MyResolver();
       }
       catch(IOException i){
           System.out.println( i.getMessage());
       }
      
       try {
           parser = 
(SAXParser)Class.forName("org.apache.xerces.parsers.SAXParser").newInstance();
           parser.setFeature("http://xml.org/sax/features/validation";, 
true);
           parser.setContentHandler(processor);
           parser.setErrorHandler(processor);
           parser.setEntityResolver(resolver);
           parser.setReaderFactory(new StreamingCharFactory());
       }
       catch (Exception ex) {
           System.out.println(ex.getMessage());
       }
   }

Well, still the same General Schema Error........
My first guess was, that I may have to set a new feature, but I couldn't 
find an appropriate feature.

I may add here, that first I wroked with JDOM, but that didn't work 
because the parser is reading from a BufferedReader wich comes from a 
Socket. Ant there is the problem with the End of File and the close the 
BufferedReader thing.

Well, I'm pretty at a loss now......
Any idea what the problem could be?

Rather than adding the resolveEntity method to your processor, you need to
create a new MyEntityResolver class that implements the EntityResolver
interface, and override the single resolveEntity method. Then pass a new
instance of this class to the parser.setEntityResolver() method. Examine
Laura's code a little more closely, and you'll notice that is what she did.
I had the exact same problem about 3 months ago, and implementing the
entityResolver solved the problem.
