Open Source Edition 3. You must install one of these or register a different server in the IDE to work through this tutorial. If you need to compare your project with a working solution, you can download the sample application. Overview of the Application When you use Struts, the framework provides you with a controller servlet, ActionServlet, which is defined in the Struts libraries that are included in the IDE, and which is automatically registered in the web. The controller servlet uses a struts-config. The Action object processes requests using its execute method, while making use of any data stored in the form bean.
Other Actions may need a file upload to be preprocessed. Another Action might need protection from a double submit.
Many Actions need dropdown lists and other controls pre-populated before the page displays. The framework makes it easy to share solutions to these concerns using an "Interceptor" strategy.
Most of the framework's core functionality is implemented as Interceptors. Features like double-submit guards, type conversion, object population, validation, file upload, page preparation, and more, are all implemented with the help of Interceptors. Interceptors can also change the state of an Action before it executes.
Your own custom Interceptors can be mixedand-matched with the Interceptors bundled with the framework. The Interceptors are defined in a stack that specifies the execution order. In some cases, the order of the Interceptors on the stack can be very important.
Rather than reiterate the same list of Interceptors, we can bundle these Interceptors together using an Interceptor Stack. Interceptor interface The AbstractInterceptor class provides an empty implementation of init and destroy, and can be used if these methods are not going to be implemented.
