Let us see the Hello World program of struts 2, files required..

  • success.jsp

  • index.jsp
  • [ in java4s package ]
  • web.xml  [ in web-inf ]
  • struts.xml  [ in web-inf/classes folder ]

Directory Structure


<%@ taglib prefix="s" uri="/struts-tags" %>

<s:form action="verify">

<s:textfield name="uname" label="Enter Username" /><br>
<s:submit value="Click" align="center" />



<%@ taglib prefix="s" uri="/struts-tags" %>
You have been successfully executed struts 2 hello world program..


<%@ taglib prefix="s" uri="/struts-tags" %>
Login failed, wrong user name, user name must be java4s

package java4s;
import com.opensymphony.xwork2.ActionSupport;
public class LogingEx extends ActionSupport{
	private static final long serialVersionUID = 1L;

	private String uname;

	public String getUname() {
		return uname;

	public void setUname(String uname) {
		this.uname = uname;

	public String execute()
			return SUCCESS;

			return ERROR;



<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="" xmlns="" xmlns:web="" xsi:schemaLocation="" id="WebApp_ID" version="2.5">


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

"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"

   <include file="struts-default.xml"/>
   <package name="a" extends="struts-default">
      <action name="verify" class="java4s.LogingEx">
         <result name="success">/success.jsp</result>
         <result name="error">/error.jsp</result>

Execution Flow

  • Right click on the project root > Run As > Run on Server
  • index.jsp will be executed automatically, because we have given index.jsp in <welcome-file></welcome-file> of web.xml file
  • Enter username as java4s and press ‘click‘ button
  • In index.jsp we have given form action as verify [ line number 5 ], so container come to web.xml and check for URL pattern and jumps to struts.xml
  • Now it will search for action name ‘verify‘, if found then corresponding java file given in class attribute will be executed [line number 10 ]
  • Now execute() method will be executed in, if condition is satisfied it will returns SUCCESS
  • Again come to struts.xml line number 11, corresponding view will be executed
  • That’s it.

After Execution


Enter java4s as user name and press click button

    When I load the index.jsp after deploying, I’m getting a warning message in the log

    org.apache.struts2.components.ServletUrlRenderer|_ThreadID=91;_ThreadName=Thread-2;|No configuration found for the specified action: ‘verify’ in namespace: ”. Form action defaulting to ‘action’ attribute’s literal value.|#]

    Hi Siva,

    I some books action class does not extend the ActionSupport class. Please explain is it necessary to extend ActionSupport or not.

  8. Sanjay says:

    Hi Nishant,

    As Action Support Class implements Action,Validetable,Validation aware,text provider,Locale provider & Serilizable interface by default, so in our Action class by Default we will get the Advantages(Methods, Constants …etc ) in our class. It Makes our Design Robust.

  16. Satyendra Mishra says:

    Hello frnd,
    In action class either we can declare SUCCESS or ERROR both as String or in return statement enclosed with(” SUCCESS”)OR (“ERROR”) by mistake he forgot to write double quote.
    In struts1.X we have tag forward and in struts2.x we are using result tag. What ever execute() method return success or error based on that it check in result tag and calls appropriate jsp file.
