Urgent: OAuth Signature Invalid in Java

[RS]

Hi,

I tried below mentioned code in Client Side and Server side. I am
getting signature_invalid. Please help what I am doing wrong?


Client Side: (Also tried with POST, but the issue is same)
------------------------------------------------------------------------------------------------------------------------------------------------
params[gadgets.io.RequestParameters.AUTHORIZATION] =
gadgets.io.AuthorizationType.SIGNED;
params[gadgets.io.RequestParameters.METHOD] =
gadgets.io.MethodType.GET;
params[gadgets.io.RequestParameters.CONTENT_TYPE] =
gadgets.io.ContentType.JSON;
gadgets.io.makeRequest(my_servlet_url, myCallBackFun,params);

Server Side:
------------------------------------------------------------------------------------------------------------------------------------------------

try
{
ByteArrayInputStream in = new
ByteArrayInputStream(CERTIFICATE.getBytes());
CertificateFactory certFac =
CertificateFactory.getInstance("X509");
X509Certificate cert =
(X509Certificate)certFac.generateCertificate(in);
OAuthServiceProvider provider = new
OAuthServiceProvider(null, null, null);
OAuthConsumer consumer = new OAuthConsumer(null,
"orkut.com", null, provider);
consumer.setProperty(RSA_SHA1.X509_CERTIFICATE,
CERTIFICATE);
OAuthMessage message = OAuthServlet.getMessage(request,
null);


OAuthAccessor accessor = new OAuthAccessor(consumer);
out.print("*** OAuthMessage Params [Before
calling:validateSignature() method] *** ");
for(java.util.Map.Entry param: message.getParameters())
{
out.print("<br>");
out.print("Param Name-->"+param.getKey());
out.print("&nbsp;");
out.print("Value-->"+param.getValue());
}
out.print("<br>");
out.print("<HERE>");
out.print(" VALIDATING SIGNATURE ");
out.print("<br>");
message.validateSignature(accessor);
result = true;
out.print("REQUEST STATUS::"+result);
out.print("<br>");
}
catch(OAuthProblemException ope)
{
out.print("<br>");
out.print("OAuthProblemException-->"+ope.getProblem());


}

Result:
