Struts 1.3 HelloWorld

Prerequisites

Step 1 Create New Maven-based Dynamic Web Project

Step 1.1 Create New Project

Go to File->New->Others… Select Dynamic Web Project under Web category then click Next. Type Struts1.3Demo or whatever name you want in the Project name field.

Step 1.2 Configure Target Runtime

  • Click New Runtime… button under Target Runtime.
  • Select Apache Tomcat v7.0. Click Next.
  • Click Browse button to specify Tomcat Server installation directory. The select the folder then click Ok.
  • Click Installed JREs… button to add/remove or edit JRE definition. Remove existing one; then click Add button to configure new one. Select Standard VM; then click Next. Click Directory button to select the root folder of JDK installation. Select the folder then click Ok. Click Finish.
  • Check the JDK then click Ok.
  • Change JRE to the JDK then click Finish.
  • Click Finish the finish the project creation.

Step 1.3 Convert The Project To Maven Project

Right click to the project; select Configure->Convert to Maven Project. Eclipse will generate Project Object Model (pom.xml) file. Open the file by Eclipse text editor then paste the content below.

Note: you can create normal java project and add jar files to your project build path. But it’s easier & faster using maven as maven is integrated with Eclipse IDE; so you don’t need to manually install it. 

Step 2 Create Web Deployment Descriptor (web.xml)

You can create web.xml when creating project or do it later. Right click to the project; select Java EE Tools -> Generate Deployment Descriptor Stub to generate web.xml.

Step 3 Create Struts Configuration file

Create an empty xml file named struts-config.xml under package WEB-INF folder and paste the content below.

Step 4 Message Bundle Properties File

  • Create new package named info.java.tips.i18n
  • Under the package create new .properties file named MessageBundle.properties

Step 5 Create Struts Action FormBean Class

Right click to the project or src folder; select New->Class. Class name & package must be the same as we declared in struts-config.xml.

Step 6 Create Struts Action Class

Right click to the project or src folder; select New->Class. Class name & package must be the same as we declared in struts.xml.

Note: simply copy the code above to clipboard, select src folder of your project in Eclipse IDE then press CTRL + V.

Step 7 Create JSP Pages

In this example we need 2 JSP files. To create JSP, simply follow the following steps:

  • Right click to the project or WebContent folder, select New -> JSP File from the menu.
  • Choose your file name then click Finish.
  • Eclipse IDE will generate some boilerplate code. We just clear all its content and replace with the following code:

Step 7.1 hello.jsp

Step 7.2 welcome.jsp

Step 8 Clean & Build

Clean & build the project to clean old classes file (if any) & force the IDE to recompile java code.

  • Go to Project on menu bar; select Clean…
  • Select Clean all projects (default)
  • Click Ok to proceed clean & build.

Step 9 Configure Tomcat

Select Servers window; in case it’s not there, go to Windows -> Show View-> Others… Select Server -> Servers; then click Ok.

If this is the first time you are creating a server, in the Servers area you will see a link as No servers are available click this link to create a new server. Click the link.

Define a New Server window will be opened, In Select the server type. Select Apache -> Tomcat v7.0 Server. Then click Finish.

Step 10 Deploy The Application

  • Right click to the Tomcat Server select Add and Remove.
  • Move the application (Struts2Demo) from Available column to Configured. Then click on Finish to deploy it to tomcat server.

Step 11 Start Tomcat Server

Right click on the tomcat server and choose Start or simply click on the green start icon to start the server.

Step 12 Run The JSP

We assume that you install tomcat on default port (8080) and project name is Struts1.3Demo. Open web browser and type:

http://localhost:8080/Struts1.3Demo/hello.jsp

Output

A form with a text box & submit button will be displayed. Enter any name such as John and click submit

Enter Mike to the text box then click submit


Note: you can configure server run time while creating project or do it later. The above video show you how to configure server runtime after creating the project.
