RequestProcessor class breaks down each request into small tasks to be carried out by different methods. Action class is the heart of the framework and acts. As you have already learnt from the Struts 2 architecture, when you click on a hyperlink or submit an HTML form in a Struts 2 web-application, the input is collected by the Controller which is sent to a Java class called Actions. After the Action is executed, a result selects a resource to render the response. The resource is generally a JSP, but it can also be a PDF file, an Excel spreadsheet.

Best Struts 2 Tutorial and Examples, Learn Struts 2 framework with the help of many examples on our website. Struts 2 Tutorial and Examples with source code. Struts 2 is open source MVC framework in Java which very popular and used by Java developers to develop applications. In this section we are giving your many Struts 2 tutorial and examples. As you learn a user sends a request from its web browser which is in the form of a URL. The request sent by the user passes through a standard filter chain which actually collected by the Controller (Filter Dispatcher). Controller examines each incoming URL request and determines which action should handle the request. Then the Controller transfers the request to the action class The Struts controller delegates most of this grunt work to the Request Processor and Action classes. In addition to being the front controller for your application, the ActionServlet instance also is responsible for initialization and clean-up of resources. When the controller initializes, it first loads the application config corresponding to the config init-param. It then goes through an. In this Struts Hello World example a web page will submit an HTML form to a server-side target named hello.action. This action will be implemented by a Struts action class named HelloWorldAction. When the execute method of the HelloWorldAction class completes successfully, a file named results.jsp will be invoked to render a result for the client. Since we will not use annotations in this. In this example, the ModelDriven interface is used to ensure that only my model, the Order object in this case, is returned to the client, otherwise, the whole OrdersController object would be serialized. Where's ActionSupport? Normally, you extend ActionSupport when writing Struts 2 actions. In these case, our controller doesn't do that.
