Tutorial: Create Struts 2 Application in Eclipse
- By Viral Patel on December 23, 2009
Welcome to the Part 2 of 7-part series where we will explore the world of Struts 2 Framework. In previous article we went through the basics of Struts2, its Architecture diagram, the request processing lifecycle and a brief comparison of Struts1 and Struts2. If you have not gone through the previous article, I highly recommend you to do that before starting hands-on today.

Things We Need
Before we starts with our first Hello World Struts 2 Example, we will need few tools.
- JDK 1.5 above (download)
- Tomcat 5.x above or any other container (Glassfish, JBoss, Websphere, Weblogic etc) (download)
- Eclipse 3.2.x above (download)
- Apache Struts2 JAR files:(download). Following are the list of JAR files required for this application.
- commons-logging-1.0.4.jar
- freemarker-2.3.8.jar
- ognl-2.6.11.jar
- struts2-core-2.0.12.jar
- xwork-2.0.6.jar
Note that depending on the current version of Struts2, the version number of above jar files may change.
Our Goal
Our goal is to create a basic Struts2 application with a Login page. User will enter login credential and if authenticated successfully she will be redirected to a Welcome page which will display message ” Howdy, <username>…!“. If user is not authenticated, she will be redirected back to the login page.
Getting Started
Let us start with our first Struts2 based application.
Open Eclipse and goto File -> New -> Project and select Dynamic Web Project in the New Project wizard screen.
After selecting Dynamic Web Project, press Next.
Write the name of the project. For example StrutsHelloWorld. Once this is done, select the target runtime environment (e.g. Apache Tomcat v6.0). This is to run the project inside Eclipse environment. After this press Finish.
Once the project is created, you can see its structure in Project Explorer.
Now copy all the required JAR files in WebContent -> WEB-INF -> lib folder. Create this folder if it does not exists.
Mapping Struts2 in WEB.xml
As discussed in the previous article (Introduction to Struts2), the entry point of Struts2 application will be the Filter define in deployment descriptor (web.xml). Hence we will define an entry of org.apache.struts2.dispatcher.FilterDispatcher class in web.xml.
Open web.xml file which is under WEB-INF folder and copy paste following code.
<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_9" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>Struts2 Application</display-name> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>Login.jsp</welcome-file> </welcome-file-list> </web-app>
The above code in web.xml will map Struts2 filter with url /*. The default url mapping for struts2 application will be /*.action. Also note that we have define Login.jsp as welcome file.
Note: The FilterDispatcher filter is deprecated since Struts version 2.1.3. If you are using latest version of Struts2 ( > 2.1.3) use StrutsPrepareAndExecuteFilter class instead.
<filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
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.viralpatel.struts2 in the source folder. This package will contain the action file.
Create a class called LoginAction in net.viralpatel.struts2 package with following content.
package net.viralpatel.struts2;
public class LoginAction {
private String username;
private String password;
public String execute() {
if (this.username.equals("admin")
&& this.password.equals("admin123")) {
return "success";
} else {
return "error";
}
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = 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 admin123.
Also note that unlike Action class in Struts1, Struts2 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 Struts2 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 ResourceBundle
ResourceBundle 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 ApplicationResources.properties file which contains static messages such as Username or Password and include this with the application.
ResourceBundle comes handy when we want to add Internationalization (I18N) support to an application.
We will define an ApplicationResources.properties file for our application. This property file should be present in WEB-INF/classes folders when the source is compiled. Thus we will create a source folder called resources and put the ApplicationResources.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 ApplicationResources.properties under resources folder.
Copy following content in ApplicationResources.properties.
label.username= Username label.password= Password label.login= Login
The JSP
We 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.jsp which will display a simple welcome message.
Create two JSP files Login.jsp and Welcome.jsp in WebContent folder of your project. Copy following content into it.
Login.jsp
<%@ page contentType="text/html; charset=UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <html> <head> <title>Struts 2 - Login Application | ViralPatel.net</title> </head> <body> <h2>Struts 2 - Login Application</h2> <s:actionerror /> <s:form action="login.action" method="post"> <s:textfield name="username" key="label.username" size="20" /> <s:password name="password" key="label.password" size="20" /> <s:submit method="execute" key="label.login" align="center" /> </s:form> </body> </html>
Welcome.jsp
<%@ page contentType="text/html; charset=UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <html> <head> <title>Welcome</title> </head> <body> <h2>Howdy, <s:property value="username" />...!</h2> </body> </html>
Note that we have used struts2 <s:> tag to render the textboxes and labels. Struts2 comes with a powerful built-in tag library to render UI elements more efficiently.
The struts.xml file
Struts2 reads the configuration and class definition from an xml file called struts.xml. This file is loaded from the classpath of the project. We will define struts.xml file in the resources folder. Create file struts.xml in resources folder.
Copy following content into struts.xml.
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.enable.DynamicMethodInvocation"
value="false" />
<constant name="struts.devMode" value="false" />
<constant name="struts.custom.i18n.resources"
value="ApplicationResources" />
<package name="default" extends="struts-default" namespace="/">
<action name="login"
class="net.viralpatel.struts2.LoginAction">
<result name="success">Welcome.jsp</result>
<result name="error">Login.jsp</result>
</action>
</package>
</struts>
Note that in above configuration file, we have defined Login action of our application. Two result paths are mapped with LoginAction depending on the outcome of execute() method. If execute() method returns success, user will be redirected to Welcome.jsp else to Login.jsp.
Also note that a constant is specified with name struts.custom.i18n.resources. 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 (ApplicationResources without .properties).
Our LoginAction contains the method execute() which is the default method getting called by Sturts2. If the name of method is different, e.g. authenticate(); then we should specify the method name in <action> tag.
<action name="login" method="authenticate" class="net.viralpatel.struts2.LoginAction">
Almost Done
We are almost done with the application. You may want to run the application now and see the result yourself. I assume you have already configured Tomcat in eclipse. All you need to do:
Open Server view from Windows -> Show View -> Server. Right click in this view and select New -> Server and add your server details.
To run the project, right click on Project name from Project Explorer and select Run as -> Run on Server (Shortcut: Alt+Shift+X, R)
But there is one small problem. Our application runs perfectly fine at this point. But when user enters wrong credential, she is redirected to Login page. But no error message is displayed. User does not know what just happened. A good application always show proper error messages to user. So we must display an error message Invalid Username/Password. Please try again when user authentication is failed.
Final Touch
To add this functionality first we will add the error message in our ResourceBundle file.
Open ApplicationResources.properties and add an entry for error.login in it. The final ApplicationResources.properties will look like:
label.username= Username label.password= Password label.login= Login error.login= Invalid Username/Password. Please try again.
Also we need to add logic in LoginAction to add error message if user is not authenticated. But there is one problem. Our error message is specified in ApplicationResources.properties file. We must specify key error.login in LoginAction and the message should be displayed on JSP page.
For this we must implement com.opensymphony.xwork2.TextProvider interface which provides method getText(). This method returns String value from resource bundle file. We just have to pass the key value as argument to getText() method. The TextProvider interface defines several method that we must implement in order to get hold on getText() method. But we don’t want to spoil our code by adding all those methods which we do not intend to use. There is a good way of dealing with this problem.
Struts2 comes with a very useful class com.opensymphony.xwork2.ActionSupport. We just have to extend our LoginAction class with this class and directly use methods such as getText(), addActionErrors() etc. Thus we will extend the LoginAction class with ActionSupport class and add the logic for error reporting into it. The final code in LoginAction must look like:
package net.viralpatel.struts2;
import com.opensymphony.xwork2.ActionSupport;
public class LoginAction extends ActionSupport {
private String username;
private String password;
public String execute() {
if (this.username.equals("admin")
&& this.password.equals("admin123")) {
return "success";
} else {
addActionError(getText("error.login"));
return "error";
}
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
And that’s it. Our first Hello World Struts2 Application is now ready.
That’s All Folks

Moving On
Now that we have created our first webapp using Struts2 framework, we know how the request flows in Struts2. We also know the use of struts.xml and properties file. In this application we implemented a preliminary form of validation. In next part we will learn more about Validation Framework in Struts2 and implement it in our example.

Create a folder named “classes” inside WEB-INF and Place your struts.xml file in it.
ensure that the class name entered in web.xml is org.apache.struts2.dispatcher.FilterDispatcher
But how about another page in my application(which is secured & need user login as compulsory) , how can we restrict or redirect user if any user request with random action url or any secured url from our app ?
where to do this ?
You can use HTTP Basic Authentication (http://docs.oracle.com/cd/E19798-01/821-1841/bncck/index.html) or Form Based Authentication (http://docs.oracle.com/javaee/5/tutorial/doc/bncbx.html#bncby) to secure your content. Also you can specify roles in your web.xml and map certain URLs to roles. This is the most basic way of implementing Authentication/Authroization. I would suggest you to check Spring Security framework which has lot of useful features that you can leverage in your application.
Nice Work bro….keep it up
thank u sir. i have successfully run this demo
Hi Harendra,
Could you please help me. I am getting a 404.
It is very nice tutoria and useful for me
thank you.
Hello, I tried to do your very detailed tutorial but the project don’t run because of this error:
“Error 500–Internal Server Error. The Struts dispatcher cannot be found. This is usually caused by using Struts tags without the associated filter.
Struts tags are only usable when the request has passed through its servlet filter, which initializes the Struts dispatcher needed for this tag. – [unknown location]
at org.apache.struts2.views.jsp.TagUtils.getStack(TagUtils.java:60)”
I’m looking for file web.xml but is in the correct directory, and I’m think that is correct:
Struts2 Application
struts2
org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
struts2
/*
Login.jsp
What can be the problem?
Thanks a lot
Hi VP,
I just wanted to check with you as to how i remove struts 1 and then start using struts 2…i tried the steps given but its not working..I have Java 6, i donno if i have installed it correctly..however when i type localhost:8080/ i am getting the tomcal welcome page..
please let me know how to identify if struts, and tomcat is installed correctly..please help me.
Raghotham
seems like you have missed couple of jars I’m using struts2.3.x its asking for
common-fileupload / io/ util /lang
java assist…. to add I’m using tomcat 7
I have uploaded all these .jar files in the application ..
commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar
commons-logging-1.0.4.jar
commons-lang-2.3.jar
ognl-3.0.jar
commons-logging-api-1.1.jar
struts2-core-2.2.1.1.jar
freemarker-2.3.16.jar
xwork-core-2.2.1.1.jar
javassist-3.14.0-GA.jar
log4j-1.2.16.jar
but still I am getting the 404 error..
the requested resource is not available..
Thanks for such a great job..
Please see to it that you have exactly same jar versions mentioned above in the tutorial. Higher versions do not work as the dispatcher fails to initialize. Keep only mentioned jars in Lib directory of your eclipse.
How can we add alert message instead of displaying text(Invalid username/password)
Little gloomy for beginner without downloading the jar files from sample download.
If the jars and the fixes mentioned by the comrades are used the application works fine.
Thanks all.
nice tutorial
i worked with this example but am getting these errors
1.Can not find the tag library descriptor for “/struts-tags”
2.Element type “action” must be followed by either attribute specifications, “>” or “/
>”.
how to add taglib in eclipse for jsp files………..
i tried with this app but am getting 404 error
that is given below.may be am thinking that some additional jars or plug ins are missed…please help wt are that files

Can some one help me please
can’t find jar files online
please help
getting this msg:-
Not Found
The requested URL /mirror/apache/dist/struts/library/struts-2.0.14-lib.zip was not found on this server.
very good, but it will be more usefull if explained how the validations.xml elements and parameters works, which jar is responsible for which task in this example so that it will be more easily for beginners to understand.
Anyways nice job and good site.
nice tutorial ,thaks
Nice tutorial – pity it doesn’t work for more than half of us
Very Nice tutorial… Thanks a lot. And one more thing is Some case this will produce some error like invocaion exceptions at that tym we have to add commons-lang3-3.1.jar file and xwork-core-2.1.6.jar.
thanks a lot for the tutorial…but i would like to say it would be much nicer if you have provided a better explanation for dependencies and classpath issues which people keep getting endless errors because of those…
My key names are displayed as label instead of values.

pls do reply for this soon…
Thank you for this tutorial
Nice tutorial. Clear and precise. But i think you have missed some of the jars that need to be added for this tutorial to work. Seeing the replies most of them are getting errors because of missing jars.
The jars that should be added are:
asm-3.3.jar
asm-commons-3.3.jar
asm-tree-3.3.jar
commons-fileupload-1.2.2.jar
commons-io-2.0.1.jar
commons-lang-2.4.jar
commons-lang3-3.1.jar
freemarker-2.3.19.jar
javassist-3.11.0.GA.jar
ognl-3.0.6.jar
struts2-core-2.3.12.jar
xwork-core-2.3.12.jar
Thanks,
Priyesh
Had some problems, but adding the correct libs according to Priyesh did the trick. I was first so naive to put all the libraries from struts2 into the lib directory but that caused conflicts.
Hi Viral, Thaks very much. It was very useful
Hi all ,Am getting 404 error like resouce bundle not available.Please help me to sort it out.
Nice Tutorial…

commons-lang3-3.1.jar
commons-logging-1.1.1.jar
freemarker-2.3.19.jar
javassist-3.11.0.GA.jar
ognl-3.0.6.jar
