xml schema conversion issue against xsd giving Illeagal exception in android applications

Question

I have written a code to validate given xml file against given xsd file in my android application. But it is giving Illeagal exception error. In some posts I saw its because of low java version. But my java version 1.6.0_20. please check the below code, Error log and suggest.

Code:

    try {
        // parse an XML document into a DOM tree
        parserFactory = DocumentBuilderFactory.newInstance();
        parserFactory.setNamespaceAware(true);
    } catch (Exception e) {
        Log.e("Exception", "ERROR Last : " + e);
        e.printStackTrace();
    }

    DocumentBuilder parser = null;
    try {
        parser = parserFactory.newDocumentBuilder();
    } catch (ParserConfigurationException e1) {
        e1.printStackTrace();
        Log.e("Exception", "ERROR 1: " + e1);
    }
    Document document = null;
    try {
        document = parser.parse(getResources().openRawResource(
                R.raw.change_pin_request_xaml));
    } catch (SAXException e1) {
        e1.printStackTrace();
        Log.e("Exception", "ERROR 2 : " + e1);

    } catch (IOException e1) {
        e1.printStackTrace();
        Log.e("Exception", "ERROR 3 : " + e1);
    }

    try {
        // create a SchemaFactory capable of understanding WXS schemas
        factory = SchemaFactory
                .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
        // W3C_XML_SCHEMA_INSTANCE_NS_URI 
        // W3C_XML_SCHEMA_NS_URI

        // load a WXS schema, represented by a Schema instance
        schemaFile = new StreamSource(getResources().openRawResource(
                R.raw.change_pin_request_xsd));
    } catch (Exception e) {
        e.printStackTrace();
        Log.e("Exception", "ERROR special " + e);
    }
    Schema schema = null;

    try {
        schema = factory.newSchema(schemaFile);
    } catch (SAXException e1) {
        Log.e("Exception", "ERROR 4 : " + e1);
        e1.printStackTrace();
    }

    // create a Validator instance, which can be used to validate an
    // instance document
    Validator validator = schema.newValidator();

    // validate the DOM tree
    try {
        try {
            validator.validate(new DOMSource(document));
        } catch (IOException e) {
            Log.e("Exception", "ERROR 5 : " + e);
            e.printStackTrace();
        }
    } catch (SAXException e) {
        Log.e("Exception", "ERROR 6 : " + e);

    }

Answer 1

This should be a comment but since I can't make comments ill make it an answer.

Right click on your project in Package Explorer > Properties > Java Compiler

and see if its compiling using 1.6. I had a weird problem and it was because eclipse was compiling in 1.5.
