This tutorial assumes you've completed the Coding Struts 2 Actons tutorial and have a working coding_actions project. The example code for this tutorial, form_processing, is available for checkout from the Struts 2 sandbox GitHub subversion repository: https://svngithub.com/apache.org/repos/asf/struts/sandbox/trunk/struts2examplesstruts-examples. |
Introduction
In this tutorial we'll explore using Struts 2 to do more involved processing of a form submission. We'll cover how to use a Java model class to store the form input and how to create the Struts 2 form to match up with that model class.
