Very Helpful, Thanks.

Thx a lot! Now I can use OLTU.

LtiVerifier ltiVerifier = new LtiOauthVerifier();

    models.PlayHttpServletRequest temp = new PlayHttpServletRequest(request);
    LtiVerificationResult ltiResult = ltiVerifier.verify(temp, SECRET);

This is giving me a nullpointer exception error, can anyone help me?

@feliperazeek any updated version for this?
