Struts 2 Configuration Files

Struts.xml file:

The struts.xml is the core configuration file for struts framework. The struts.xml is used to initialize the resources like Interceptors, Action classes and Results.


   <package name="packageName" extends="struts-default">
      <action name="actionName" class="actionClass" method="methodName">
            <result name="success">/HelloWorld.jsp</result>
      //more actions.
   //more packages.

Commonly used attributes:

1. package attribute: It is used for modularization. You can divide configuration into multiple modules.

2. action attribute: It is a sub-attribute of the package attribute. It represents an action.

3. result attribute: It is a sub-attribute of the action attribute. It is used to control the flow after an action is executed.


The web.xml is known as deployment descriptor. It is used for providing entry point in any web application. In struts 2 we have to define FilterDispatcher class entry in web.xml.

web.xml file example:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
