java.lang.StackOverflowError when validating Xml

[Stephen ODonnell]

Hi all,

I am getting a java.lang.StackOverflowError when I try to validate an xml response. Below is the code i use:

  
private void compareResponses(StringBuffer requestXml, String responseFilePath, String actualResponseXml, String requestXSD, String responseXSD)throws ExceptionMessageHandler
    {
        log.info("compareResponses()");
        StringBuffer expectedResponseXml = new StringBuffer();
        expectedResponseXml = Utility.fileToStringBuffer(responseFilePath);
 
        // Check if the XMLs validate
        if (  Utility.validateXML(requestXml.toString(), requestXSD)
       && Utility.validateXML( actualResponseXml, responseXSD ) 
       && Utility.validateXML( expectedResponseXml.toString(), responseXSD))
        {
   assertEquals("Response XMLs didn't match", expectedResponseXml.toString(), actualResponseXml);
        } else
        {
            fail("XML validation failed");
        }
    }

**** ValidateXml() ****

  
public static boolean validateXML(String xml, String schemaURI) throws ExceptionMessageHandler
{
    log.info("validateXML()");
    try
    {
        // use autodetection of schemas
        VerifierFactory factory = new com.sun.msv.verifier.jarv.TheFactoryImpl();
        Schema schema = factory.compileSchema(schemaURI);
 
        // configure a Vertifier
        Verifier verifier = schema.newVerifier();
 
        verifier.setErrorHandler(new ErrorHandler()
        {
            public void error(SAXParseException saxParseEx)
            {
                log.error("Error during validation.", saxParseEx);
            }
            public void fatalError(SAXParseException saxParseEx)
            {
                log.fatal("Fatal error during validation.", saxParseEx);
            }
 
            public void warning(SAXParseException saxParseEx)
            {
                log.warn(saxParseEx);
            }
        });
 
        // starting validation by resolving the dom4j document into sax
        VerifierHandler handler = verifier.getVerifierHandler();
        SAXWriter writer = new SAXWriter(handler);
        Document doc = DocumentHelper.parseText(xml);
        writer.write(doc);
 
        return handler.isValid();
    } catch (DocumentException e)
    {
        log.error("Caught DocumentException", e);
    }
.
.
.
}
 

The error occurs when I try to validate the second xml file.

Any help would be greatly appreciated,
Many thanks,
Stephen.
