I have a spring social enabled app which I built using spring-social-samples as a reference. I successfully integrated facebook and Twitter but I am having trouble integrated with Sparklr(code) and I am getting the following error.
[DEBUG] ProtectedResourceProcessingFilter - org.springframework.security.oauth.provider.Invali dOAuthParametersException: Missing signature method.
Here is the (code) which is throwing this error.
Spring-security-oauth comes with Sparklr(Service provider) and Tonr(Consumer). Everything works as expected when I try to authorize Tonr user against Sparklr. It fails when I try to authorize my app user against Sparklr.
Question really is, how is method signature sent? Is this some kind of configuration error in my app?
