javax.xml.stream.XMLStreamException: Undeclared prefix 'soapenv' for element <soapenv:Envelope>

[Praveen Kumar Jayaram]

Hi

Am trying to access a SharePoint webservice from Axis2 Java client in Linux box.....
The code works fine in Windows but in Linux I get a Exception:

Here is the code:

public class WebserviceClient {

	private Logger logger = LoggerFactory.getLogger(WebserviceClient.class);
	
	public static String getData() throws Exception{

		serviceClient.setOptions(opts);
		OMElement res = null;
		try{
			res = serviceClient.sendReceive(createPayLoad());
			xmlData = res.toString();
			System.out.println(res.toString());
		}catch(AxisFault af){
			System.out.println(af.getMessage());
			System.out.println(af.getReason());
		}
		return xmlData;
	}
	
	public static OMElement createPayLoad() {
        OMFactory fac = OMAbstractFactory.getOMFactory();
        OMNamespace omNs = fac.createOMNamespace(
        		"http://tempuri.org/", "soap");
        OMElement method = fac.createOMElement("getExportContents", omNs);
        OMElement value = fac.createOMElement("strDocLibName", omNs);
        value.setText("Export");
        method.addChild(value);
        return method;
	}
	
	public static void main(String[] args) {
		try{
		WebserviceClient.getData();
		}catch(Exception e){
			System.out.println(e.getMessage());
			e.printStackTrace();
		}
	}
}

Any idea why this can happen?
