Your schema validates with both XSV and XML Spy.

All the best, Ashok

Dear Sir:

I have an XSD file something like this.

<xsd:schema xmlns:xsd='http://www.w3.org/2001/XMLSchema'>

   <xsd:annotation>
		<xsd:documentation xml:lang="en">
		</xsd:documentation>
	</xsd:annotation>

   <xsd:element  type="WITHDRAWType" name="WITHDRAW"/>
   <xsd:complexType name="WITHDRAWType">
<!-- Made up of simple definitions. -->
</xsd:complexType>
</xsd:schema>

I have an instance file and OracleXML Schema Validator sample program.


import oracle.xml.parser.schema.*;
import oracle.xml.parser.v2.*;
import oracle.xml.parser.v2.XMLParser;


import java.net.*;
import java.io.*;
import org.w3c.dom.*;
import java.util.*;

public class XSDSetSchema
{
   public static void main(String[] args) throws Exception
   {
      if (args.length != 2)
      {
         System.out.println("Usage: java XSDSample <schema_file>
<xml_file>");
         return;
      }

      XSDBuilder builder = new XSDBuilder();
      URL    url =  createURL(args[0]);

      // Build XML Schema Object
      XMLSchema schemadoc = (XMLSchema)builder.build(url);
      process(args[1], schemadoc);
   }

   public static void process(String xmlURI, XMLSchema schemadoc)
   throws Exception
   {

      DOMParser dp  = new DOMParser();
      URL       url = createURL (xmlURI);

      // Set Schema Object for Validation
      dp.setXMLSchema(schemadoc);
      dp.setValidationMode(XMLParser.SCHEMA_VALIDATION);
      dp.setPreserveWhitespace (true);

      dp.setErrorStream (System.out);

      try
      {
         System.out.println("Parsing "+xmlURI);
         dp.parse (url);
         System.out.println("The input file <"+xmlURI+"> parsed without
errors");
      }
      catch (XMLParseException pe)
      {
         System.out.println("Parser Exception: " + pe.getMessage());
      }
      catch (Exception e)
      {
         System.out.println ("NonParserException: " + e.getMessage());
      }

   }

   // Helper method to create a URL from a file name
   static URL createURL(String fileName)
   {
      URL url = null;
      try
      {
         url = new URL(fileName);
      }
      catch (MalformedURLException ex)
      {
         File f = new File(fileName);
         try
         {
            String path = f.getAbsolutePath();
            // This is a bunch of weird code that is required to
            // make a valid URL on the Windows platform, due
            // to inconsistencies in what getAbsolutePath returns.
            String fs = System.getProperty("file.separator");
            if (fs.length() == 1)
            {
               char sep = fs.charAt(0);
               if (sep != '/')
                  path = path.replace(sep, '/');
               if (path.charAt(0) != '/')
                  path = '/' + path;
            }
            path = "file://" + path;
            url = new URL(path);
         }
         catch (MalformedURLException e)
         {
            System.out.println("Cannot create url for: " + fileName);
            System.exit(0);
         }
      }
      return url;
   }

}

When I run, 
> java XSDSetSchema out.xsd withdraw.xml

I get error :

<Line 38, Column 26>: XSD-2028: (Error) Invalid reference:
':WITHDRAWType'
Exception in thread "main" oracle.xml.parser.schema.XSDException:
Invalid
reference: ':WITHDRAWType
        at
oracle.xml.parser.schema.XSDBuilder.buildSchema(XSDBuilder.java:471)
        at

        at
oracle.xml.parser.schema.XSDBuilder.build(XSDBuilder.java:240)
        at XSDSetSchema.main(XSDSetSchema.java:26)

I don't understand why WITHDRAWType is INVALID ref. b'se it has been
defined
Thanks for your time
