Certificate authentication from c++ to java

[neetika sharma]

We have a c++ server running on tier3 and this c++ service has to acccess the java service within the application server. i.e the servlet running on the appserver has to be accessed from c++ service. Here the web service is implemented as an EJB.
Now the question is how do I follow certificate for authentication on J2EE server side. How and what for of certificate should I use?
Please suggest if any exists?

Though you may be preparing for SCWCD, this question has nothing to do with SCWCD. I'm moving this thread to a different forum where it ought to feel more at home...
