How to load a XML-Schema (XSD) from Classpath

Question

Hi
I want to perform XML Schema Validation using a XML-Schema stored in a File "MySchema.xsd" in the classpath.
Unfortunately I have no clue, how I can load this file without using an absolute path. I already tried:
Thread.currentThead().getContextClassLoader().getRessourceAsStream()but this method rejects to load Files with the extension XSD.It does however load the file, if I rename it to MySchema.xml or MySchema.properties, but then I cannot use the Visual Editors of JDeveloper to edit the File.
Has anyone an idea, how I can load a XSD-File stored in the classpath?
Thanks in advance

My Problem is, that I cannot load the Schema-File during runtime. I try to use code like this:
  String Schema = "sam/model/dataaccess/message/NavMessageXSD.xml";  // <== works with .xml, fails with .xsd
  ClassLoader loader = Thread.currentThread().getContextClassLoader();
  InputStream is = loader.getResourceAsStream(Schema);
  if (is==null)
    throw new Exception("Ressource not found");   // <== Exception thrown with .xsd
  XSDBuilder builder = new XSDBuilder();
  schemadoc = builder.build(new InputSource(is));
  DOMParser parser = new DOMParser();
  parser.setValidationMode(XMLParser.SCHEMA_VALIDATION);
  parser.setXMLSchema(schemadoc);This code works if "Schema" points to a file with extension .xml ("NavMessageXSD.xml"). It fails if "Schema" points to a file with extension .xsd ("NavMessageXSD.xsd").
This file is already part of my project. If it is named "NavMessageXSD.xsd" I can edit it using the visual editor. If it is named "NavMessageXSD.xml" it is just an ordenary XML-File.
Thanks for your help
