Now copy all the required JAR files in Web. Content WEB INF lib folder. Create this folder if it does not exists. Mapping Struts. 2 in WEB. As discussed in the previous article Introduction to Struts. Struts. 2 application will be the Filter define in deployment descriptor web. Hence we will define an entry of org. Filter.

Filter class instead. Struts. Prepare. And. Execute. Filterlt filter class. The Action Class. We will need an Action class that will authenticate our user and holds the value for username and password. For this we will create a package net. This package will contain the action file. Create a class called Login. Action in net. viralpatel. Login. Action. private String username. String password. public String execute. String get. Username. UsernameString username. String get. Password. PasswordString password. Note that, above action class contains two fields, username and password which will hold the values from form and also contains an execute method that will authenticate the user. In this simple example, we are checking if username is admin and password is admin. Also note that unlike Action class in Struts. Struts. 2 action class is a simple POJO class with required attributes and method. The execute method returns a String value which will determine the result page. Also, in Struts. 2 the name of the method is not fixed. In this example we have define method execute. You may want to define a method authenticate instead. The Resource. Bundle. Resource. Bundle is very useful Java entity that helps in putting the static content away from the source file. Most of the application define a resource bundle file such as Application. Resources. properties file which contains static messages such as Username or Password and include this with the application. Resource. Bundle comes handy when we want to add Internationalization I1. N support to an application. We will define an Application. Resources. properties file for our application. This property file should be present in WEB INFclasses folders when the source is compiled. Thus we will create a source folder called resources and put the Application. Resources. properties file in it. To create a source folder, right click on your project in Project Explorer and select New Source Folder. Specify folder name resources and press Finish. Create a file Application. Resources. properties under resources folder. Copy following content in Application. Resources. properties. The JSPWe will create two JSP files to render the output to user. Login. jsp will be the starting point of our application which will contain a simple login form with username and password. On successful authentication, user will be redirected to Welcome. Create two JSP files Login. Welcome. jsp in Web. Content folder of your project. Copy following content into it. Login. jsplt page content. Typetexthtml charsetUTF 8.

Struts. 2 reads the configuration and class definition from an xml file called struts. This file is loaded from the classpath of the project. We will define struts. Create file struts. Copy following content into struts. UTF 8. lt DOCTYPE struts PUBLIC. Apache Software FoundationDTD Struts Configuration 2. EN. http struts. Dynamic. Method. Invocation. Mode valuefalse. Application. Resources. Login. Action. Welcome. jsplt result. Login. jsplt result. Note that in above configuration file, we have defined Login action of our application. Two result paths are mapped with Login. Action depending on the outcome of execute method. If execute method returns success, user will be redirected to Welcome. Login. jsp. Also note that a constant is specified with name struts. This constant specify the resource bundle file that we created in above steps. We just have to specify name of resource bundle file without extension Application. Resources without. Our Login. Action contains the method execute which is the default method getting called by Sturts. If the name of method is different, e. Login. Action. Almost Done. We are almost done with the application.
