This section discusses Struts 2 zero configuration feature with example. The Struts 2 zero configuration is another very interesting and attractive feature to make development much easier.
Any "Zero Configuration" Struts 2 application uses annotations to register the actions. There is no need to write xml configuration or property files. In order to configure the actions we have to just specify the packages and Struts 2 will read the classes, create actions based on the class name and then register it with the system.
Steps to Configure and use Zero Configuration
You simply specify a path to your action packages and Struts will read the classes, create actions based on the class name and register it with XWork. Once you combine this with the annotation support for action classes which enables you to define results and namespaces, the struts.xml (or should I say xwork.xml) goes out the window.
