使用XSD解析XML消息

通过JMS侦听器接收xml消息,并根据XSD验证消息 . 虽然消息有效,但有时消息被视为无效,并引发以下异常 .

xml消息未使用UTF-8编码,消息只是以root开头和结尾 .

Msg Format :
<root>
<Message>Sample Message</Message>
</root>

尽管有效,但导致消息无效的问题可能是什么 .

Websphere服务器 - 6.1 JDK版本1.6 Spring版本 - 2.3x

Parser Code :

        InputStream inputStream = getResource().getInputStream();
        Source schemaSource = new SAXSource(new InputSource(inputStream));
        Schema schema = getSchemaFactory().newSchema(schemaSource);
        ValidatorHandler validatorHandler = schema.newValidatorHandler();
        validatorHandler.setContentHandler(this);
        parser = getParser();
        parser.setContentHandler(validatorHandler);
                InputStream iStream = new ByteArrayInputStream(asyncMsg.getBytes());
        InputSource inputSource = new InputSource(iStream);
