Introduction
In our previous tutorials we've been using an XML file (struts.xml) to configure our applications. The XML file wires up the action names (register), with ActionSupport classes (RegisterAction.java), and with the result to render back to the browser (register.jsp). Struts 2 provides an alternative to using XML to configure your application by using standard naming conventions and annotations for your action names, ActionSupport classes, and results.
