I am new to java programming. I am trying to implement a java servlet that processes google in app payments. I am trying to work my way through the code snippet that they provided. The code they have verbatim is below. My first question is how do I set up the servlet? Do I put a call in the doPost method of the servlet? If I leave it outside, the container wont call it right? What calls the getJWT() method? Third what do I do with the String that the method returns?
