Featured, How-To, Struts, Tutorial

Note: If you looking for tutorial “Create Struts2 Application in Eclipse” Click here.
In this tutorial we will create a hello world Struts application in Eclipse editor. First let us see what are the tools required to create our hello world Struts application.

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 Struts JAR files:(download). Following are the list of JAR files required for this application.
- struts.jar
- common-logging.jar
- common-beanutils.jar
- common-collections.jar
- common-digester.jar

We will implement a web application using Struts framework which will have a login screen. Once the user is authenticated, (s)he will be redirected to a welcome page.

Let us start with our first struts based web 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.

Next step is to create a servlet entry in web.xml which points to org.apache.struts.action.ActionServlet class of struts framework. Open web.xml file which is there under WEB-INF folder and copy paste following code.

<servlet>
		<servlet-name>action</servlet-name>
		<servlet-class>
			org.apache.struts.action.ActionServlet
		</servlet-class>
		<init-param>
			<param-name>config</param-name>
			<param-value>/WEB-INF/struts-config.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
	<servlet-name>action</servlet-name>
	<url-pattern>*.do</url-pattern>
</servlet-mapping>

Here we have mapped url *.do with the ActionServlet, hence all the requests from *.do url will be routed to ActionServlet; which will handle the flow of Struts after that.

We will create package strutcures for your project source. Here we will create two packages, one for Action classes (net.viralpatel.struts.helloworld.action) and other for Form beans(net.viralpatel.struts.helloworld.action).

Also create a class LoginForm in net.viralpatel.struts.helloworld.action with following content.

package net.viralpatel.struts.helloworld.form;

import javax.servlet.http.HttpServletRequest;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionMessage;

public class LoginForm extends ActionForm {

	private String userName;
	private String password;

	public ActionErrors validate(ActionMapping mapping,
			HttpServletRequest request) {

		ActionErrors actionErrors = new ActionErrors();

		if(userName == null || userName.trim().equals("")) {
			actionErrors.add("userName", new ActionMessage("error.username"));
		}
		try {
		if(password == null || password.trim().equals("")) {
			actionErrors.add("password", new ActionMessage("error.password"));
		}
		}catch(Exception e) {
			e.printStackTrace();
		}
		return actionErrors ;
	}

	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;
	}
}

LoginForm is a bean class which extends ActionForm class of struts framework. This class will have the string properties like userName and password and their getter and setter methods. This class will act as a bean and will help in carrying values too and fro from JSP to Action class.
Let us create an Action class that will handle the request and will process the authentication. Create a class named LoginAction in net.viralpatel.struts.helloworld.action package. Copy paste following code in LoginAction class.

package net.viralpatel.struts.helloworld.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import net.viralpatel.struts.helloworld.form.LoginForm;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class LoginAction extends Action {

	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response)
			throws Exception {

		String target = null;
		LoginForm loginForm = (LoginForm)form; 

		if(loginForm.getUserName().equals("admin")
				&& loginForm.getPassword().equals("admin123")) {
			target = "success";
			request.setAttribute("message", loginForm.getPassword());
		}
		else {
			target = "failure";
		}

		return mapping.findForward(target);
	}
}

In action class, we have a method called execute() which will be called by struts framework when this action will gets called. The parameter passed to this method are ActionMapping, ActionForm, HttpServletRequest and HttpServletResponse. In execute() method we check if username equals admin and password is equal to admin123, user will be redirected to Welcome page. If username and password are not proper, then user will be redirected to login page again.

We will use the internationalization (i18n) support of struts to display text on our pages. Hence we will create a MessagesResources properties file which will contain all our text data. Create a folder resource under src (Right click on src and select New -> Source Folder). Now create a text file called MessageResource.properties under resources folder.

Copy the following content in your Upadate:struts-config.xml MessageResource.properties file.

label.username = Login Detail
label.password = Password
label.welcome = Welcome

error.username =Username is not entered.

Create two JSP files, index.jsp and welcome.jsp with the following content in your WebContent folder.

index.jsp

<%@taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html"%>
<%@taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %>

<html>
	<head>
		<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
		<title>Login page | Hello World Struts application in Eclipse</title>
	</head>
	<body>
	<h1>Login</h1>
	<html:form action="login">
		 <bean:message key="label.username" />
		 <html:text property="userName"></html:text>
		 <html:errors property="userName" />
		 <br/>
		 <bean:message key="label.password"/>
		<html:password property="password"></html:password>
		 <html:errors property="password"/>
		<html:submit/>
		<html:reset/>
	</html:form>
	</body>
</html>

welcome.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
	<head>
		<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
		<title>Welcome page | Hello World Struts application in Eclipse</title>
	</head>
	<body>
	<%
		String message = (String)request.getAttribute("message");
	%>
		<h1>Welcome <%= message %></h1>

	</body>
</html>

Now create a file called struts-config.xml in WEB-INF folder. Also note that in web.xml file we have passed an argument with name config to ActionServlet class with value /WEB-INF/struts-config.xml.

Following will be the content of struts-config.xml file:

<?xml version="1.0" encoding="ISO-8859-1" ?>

<!DOCTYPE struts-config PUBLIC
          "-//Apache Software Foundation//DTD Struts Configuration 1.2//EN"
          "http://jakarta.apache.org/struts/dtds/struts-config_1_2.dtd">

<struts-config>
	<form-beans>
		<form-bean name="LoginForm"
			type="net.viralpatel.struts.helloworld.form.LoginForm" />
	</form-beans>

	<global-exceptions>
	</global-exceptions>
	<global-forwards></global-forwards>

	<action-mappings>
		<action path="/login" name="LoginForm" validate="true" input="/index.jsp"
			type="net.viralpatel.struts.helloworld.action.LoginAction">
			<forward name="success" path="/welcome.jsp" />
			<forward name="failure" path="/index.jsp" />
		</action>
	</action-mappings>

	<message-resources parameter="resource.MessageResource"></message-resources>

</struts-config>

And, that’s it :) .. We are done with our application and now its turn to run it. I hope you have already configured Tomcat in eclipse. If not then:

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)

Copy the following content in your struts-config.xml file.

label.username = Login Detail
label.password = Password
label.welcome = Welcome
error.username =Username is not entered.

did u mean that paste the above content in MessageResource.properties file? or struts-config.xml file?

Viral wrote on 19 January, 2009, 12:05

Thanks Vivek,
I have updated the error in post.
You need to copy this in MessageResource.properties file.

Thanks again.

You should have take the time to make this tutorial with the latest version of struts 1 : v1.3.10
The version 1.2, on which is based this tutorial, has been released for more than 4 years ! The branch 1.3 which split struts.jar into multiple modules has been release in two years !

Greetings!

I found your post very educating. This is the first sample struts application I created using eclipse.

However, I kept getting the error saying the message was not found in the key bundle.

I tried many things but I got the same error. Finally I modified the entry in the struts-config.xml to
from what you mentioned. It did the trick.

I’m using struts 1.3, jdk 6 and eclipse ganymede.. hope that helps.

Hello There,

I am fairly new to Struts, I was wondering if anyone can post or preferably mail me some materila about how to handle database connectivity in Struts. I am working on JNDI but I guess this won\\\’t be helpful if I have a shared apache tomcat server as that won\\\’t let me access the server.xml file.

I am preety new to struts. I want to know how to remove the error Missing message for key \"label.username\"? I have created a package name resource in src and created a file in it with the name MessageResource.properties. What changes i need to make in my struts-config.xml?

Viral Patel wrote on 19 March, 2009, 11:20

Hi Payal,
I am not sure if I got your problem. What I understand is that you want to remove the error messages generated from keys that are missing in your bundle MessageResource file. If this is the case then you can use null attribute in <message-resources> tag in struts-config.xml file.

null attribute will control the messages, If true, references to non existing messages results in null and If false, references to non existing messages result in warning message like
???KeyName???
Hope this will solve your query.

Hey thanks for this great tut!!

But, I was having the same error “Missing message for key “label.username” and I moved the file MessageResource to the folder WEB-INF->classes->resource. That did the trick.

Can you explain why tis happened? Thanks again mate!

Viral Patel wrote on 19 March, 2009, 12:36

While providing the parameter attribute in <message-resource> tag we provide it as parameter=”resource.MessageResource”. Thus in this case, struts expects the MessageResource.properties file under resource folder. But if you have provided parameter=”MessageResource” then that means your MessageResource properties file is directly under classes folder.

Hi..

To make this tutorial work:

1. also add servlet-api.jar.
2. make sure struts-config.xml is in web-inf folder or the folder u have specified in web.xml
3. make sure the messageresource file is in web-inf/classes folder.
4. Change the following line in LoginAction.java from
request.setAttribute(\"message\", loginForm.getPassword());
To
request.setAttribute(\"message\", loginForm.getUserName());

To make this tutorial work then follow these steps:

1. also inlcude servlet-api.jar in lib folder.
2. make sure struts-config.xml is in web-inf folder or the folder u have specified in web.xml
3. make sure the MessageResource.properties file is in web-inf/classes/resource folder.
4. Change the following line in LoginAction.java from
request.setAttribute("message", loginForm.getPassword());
To
request.setAttribute("message", loginForm.getUserName());
Change the following line in struts-config.xml
from
<message-resources parameter="resource.MessageResource"></message-resources>

could you help?

Viral Patel wrote on 21 July, 2009, 17:11

Hi Salma,
The error you are getting is due to the difference in the struts jar file. Check which version of jar you using and add the appropriate taglib paths in your jsp. For example try following URIs in the path of taglib.
http://struts.apache.org/tags-html
http://struts.apache.org/tags-bean

Struts 2 is very different from Struts 1. You must use a version of Struts 1.2.x for the tutorial to work (no, 1.3.x won’t work either). Also, make sure you change Welcome.jsp to welcome.jsp in strut-config.xml once you get it working with Struts 1.2.x or else you’ll get a 404 error.

Hi Sue, It may be possible that an instance of Tomcat is already running when you are trying to run it from Eclipse. Try to change few port numbers in server.xml file and see if the problem gets resolved.
To know which ports to change see this article: Running multiple tomcat instances

I am guessing all this has got to do with the taglib. The url u mentioned http://jakarta.apache.org/tags-html doesnot exist. Even when I use it on d browser, it says not found. Kindly help!!!

@Namrata, I can see the stacktrace is complaining about Missing message for key “label.username”. Can you check if your message properties file is included properly and it contains label.username key?

No Java compiler was found to compile the generated source for the JSP.
This can usually be solved by copying manually $JAVA_HOME/lib/tools.jar from the JDK

Ok,

thanks for the tutorial, this was my first start in struts. I had to do some tweaks to get this tutorial running. I am using Ubuntu 10.04 and Eclipse 3.5.

1) Make sure that Ubuntu uses Suns Java Virtual Machine, more precisely sun-java6-jdk.
2) Maybe you have to set the environment variable JAVA_HOME. To achieve this, I modified the .bashrc-File on my machine.
3) I used Tomcat as my web-container, but not the Ubuntu-package! Grab Tomcat from the apache website. The Ubuntu-package is splitted and Eclipse will get problems to find ‘conf’-directory.
4) There are some conflicts in this tutorial, go for description in code/images, if you are in doubt. For example you should place class ‘LoginForm’ in package ..helloworld.form not ..helloworld.action as it is stated one line above written code.
5) My application runs as I placed the ResourceMessage.properties-file directly in the src-Folder, so I did not create a special resource-Folder.
6) I went through all files to make sure, all paths are set up correctly. Especially, you have to adjust struts-config.xml if you modified some package-names or the directory of ResourceMessage.properties.

After those steps – all went fine for me. Good luck.

For the error Missing message for key “label.username” just give in struts config.xml instead of MessageResource.properties

ratman wrote on 16 August, 2010, 19:27

that prob with “Missing message for key “label.username” ” .. there could be problem with Eclipse which doesn’t see folder resources … try to get file MessageResources.properties into some folder (package) INSIDE “src” folder. don’t forget to change the destination in the struts-config.xml. it worked for me.
