Re: Still have problems validating xml file with xsd schema

[Marcus Schneller]

Hi again,
hope that will not be quallified as spamming ;-)

I think the problem starts earlier. I have a System.out.println("Hello"); statement at the beginnig of the method resolveEntity(String publicId, Sring systemId). The Statement is never reached, so I think the method is never called, but why?

Marcus,

Try this:

schema = new InputSource("file:///F:/ZHW/test/ReqSchema.xsd");

That worked for me in a similar situation while trying to resolve the path
to my dtd location, so maybe it will work for you in this case. If not, I
defer to higher authority (ie: someone else who has a clue   ;-)

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").newIns
tanc
e();
            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.
