Hi, I have a Cognos based application that needs to invoke a servlet for authentication. The Cognos Access Manager has a C++ method. I need to invoke the authentication servlet from inside this method. Since it is enterprise security mechanism, I don't have much choice about the security authentication. The servlet is a blackbox to the applications. Is there a way I can invoke this servlet from inside the C++ method either by simulating a HTTP client or socket ? Thank You Bala.
