oauth_problem_advice: Failed to validate signature

[GoogleCodeExporter]

This's my code in Maventproject

public void testKey() {
    try {

        XeroClient xeroClient = null;
        xeroClient = new XeroClient(endpointUrl, consumerKey, consumerSecret, praviteKey);

        xeroClient.postContacts();
    } catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
    }
}


public void postContacts() {
    try {

        String postXML = "<Contact>" + "<Name>Contact Name</Name>" + "<ContactNumber>002</ContactNumber>" + "</Contact>";
        OAuthClient client = new OAuthClient(new HttpClient3());
        OAuthAccessor accessor = buildAccessor();
        OAuthMessage m = client.invoke(accessor, OAuthMessage.PUT, endpointUrl + "Contacts", OAuth.newList("xml", postXML));
        System.out.println(OAuthMessage.readAll(m.getBodyAsStream(), "UTF-8"));
    } catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
    }
}
