I am building an application which will eventually 'talk' to our mainframe system. What I will need to do is present a form to collect the student's ID. Then pass that on to the class which connects to the MF and sends data back. If valid ID then get the PIN from student and pass that to MF for validation and back to Servlet again. The mainframe communication parts works well and I have used Servlets that do basically one-way inquiries. But, now I need to get data and validate it on the MF and handle it all within the one Servlet. This is where I am stuck. I have been building a test model and just keep calling the Servlet using the generated forms with increasing depth levels. I keep getting NullPointerErrors and others. The mainframe aside, this is a general question of how to handle calling the same Servlet over and over again and getting deeper into the logic contained within. Am suggestions are appreciated. An off-list discussion would be great if anyone is willing.
