Validate XML file using nested XSD's

Question

Hi,
I am currently trying to create a method that can validate a XML document based on a long series of nested XSD's.
I am however not sure of how to implement this validation with the nested XSD's.
Currently I have created the following function:
     public void validate(InputStream xmlDocument) {
          try {
               SAXParserFactory spf = SAXParserFactory.newInstance();
               spf.setNamespaceAware(true);
               spf.setValidating(true);
               SAXParser sp = spf.newSAXParser();
               InputStream schema1 = this.getClass().getResourceAsStream("schema.xsd");
               InputStream schema2 = this.getClass().getResourceAsStream("schema1.xsd");
               Object[] schemas = {schema1,schema2};
               final String JAXP_SCHEMA_LANGUAGE = "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
               final String W3C_XML_SCHEMA = "http://www.w3.org/2001/XMLSchema";
               final String JAXP_SCHEMA_SOURCE = "http://java.sun.com/xml/jaxp/properties/schemaSource";
               sp.setProperty(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
               sp.setProperty(JAXP_SCHEMA_SOURCE, schemas);
               sp.parse(xmlDocument, new ParseErrorHandler());
          } catch (SAXException e) {
               System.out.println(e.toString());
          } catch (ParserConfigurationException e) {
               System.out.println(e.toString());
          } catch (IOException e) {
               System.out.println(e.toString());
The schemas that I reference are imported into the namespace of the class that contains the above method. schema.xsd contains a reference to schema1.xsd.
The exception that I get is:
com.sap.engine.lib.xml.parser.NestedSAXParserException: Generic Exception: -> com.sap.engine.lib.xml.util.NestedException: [location : null] ERROR : schema1.xsd (The system cannot find the file specified)
This I dont understand since the schema1.xsd is located right along with schema.xsd which is found without trouble.
Hope someone can clearify this issue for me, since I'm somewhat lost.
Best regards,
Daniel
