JMS and XML SAX

Question

I am attempting to pass an XML encoded string from one java class to another using JMS. The SAX implementation requires either a File, InputSource, InputStream, or String uri object in order to parse the XML. I can pass the String as either a String or MessageStream using JMS, but have been unable to cast the MessageStream to InputStream to make it parse correctly (also tried casting to InputSource but am unsure how that works).
Has anyone else tried this setup to do this sort of thing?
Any other ideas?
Thanks,
Ed.

If you pass the XML in a String, you then need to convert that String into an input source. I have used the following:
public static Document parseXMLString(String sXML)
    try {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder docBuilder = factory.newDocumentBuilder();
        Document doc = docBuilder.parse(new InputSource(new StringReader(sXML)));
        Element ndroot = doc.getDocumentElement();
        return doc;
    } catch (javax.xml.parsers.ParserConfigurationException e) {
        // print an error
    } catch (java.io.IOException e) {
        // print an error
    } catch (org.xml.sax.SAXException e) {
        // print an error
    return null;
}
