I am trying to learn java servlet/jsp with the MVC concept and built the simplest MVC application. Now I want give more detail to it to enhance my understanding.

If I would need to register a new row in a table in the database, how should we pass the various value of column into the system?

For example, the user might want to register a new event in his planner and the detail of the event involves the 'where', 'when', 'who', 'detail', etc. Should pass all this long value from the servlet's parameter, i.e: the http link?

String accNo = request.getParameter("account_number");
String a = request.getParameter("...");
String b = request.getParameter("...");
String c = request.getParameter("...");
String d = request.getParameter("...");

To illustrate my view that it is really unprofessional to show all the parameter on the link:

http://localhost:8080/domain1/servlet1?param1=55555555555555&param2=666666666666666666666666666666666666666666666666666666666666&param3='Some random detail written by user.........................'

Is there other way to pass them?
