Overview
In this guide, you create a JSP Page and a Controller Class that interact to:
- Add records to a Mailing List object
- Do a SQL search for (one or more) records
- Update records
A sample interaction scenario might look like this:
-
- The arrows going to the controller show the value of the action variable that is passed from the JSP Page.
- The arrows going to the JSP Page show the value of the control variable that is passed from the controller
- (The names of the variable are determined by convention.)
This diagram shows how the interactions between the JSP Page and controller class take place:
Prerequisites
- A "Mailing List" object must created, with two fields: contact_name and contact_email
