How to use mkyong tutorial

Recently, received many emails for tutorials, about how to deploy the project to Tomcat, build the project with Maven, and also how to import it into Eclipse IDE.

Actually, almost all the tutorials are developed in Eclipse IDE (3.6 or 3.7), build with Maven (version 2 or 3) and deploy to Tomcat.

At the end of the tutorial, the entire Eclipse’s project and source code are zipped and provide user to download.

In this demonstration, we are using this “Struts 2 hello world example” tutorial, to show you how to download the project, build and import it into Eclipse IDE.

Hope this guide will help others to use the mkyong tutorial more easily. For those familiar with Maven and Eclipse, you can skip this guide.

1. Requirement

To use the tutorial, make sure you have following tools installed, and have some basic understanding about it, especially Maven.

  1. Installed Tomcat
  2. Installed Maven
  3. Installed Eclipse

2. Download Project

Scroll down to the end of the article, click on the download link.

3. Project Structure

Extract the downloaded zip file.

In this example, extract the zip files to following folder :


See following extracted project structure, a standard Eclipse + Maven project structure.

To reduce the zip file size, i deleted all the classes in “target” folder, you need to build it to make it works, see next step.

4. Maven Build

Issue following Maven command to build the project :

mvn eclipse:eclipse -Dwtpversion=2.0

In this example, Windows, command prompt, build like this.

C:\Users\mkyong\Downloads\Struts2Example>mvn eclipse:eclipse -Dwtpversion=2.0

This tell Maven to download the entire project’s dependencies declared in pom.xml, and configure the deployment path in Eclipse properly… it make everything ready for developing and deployment.

5. Import into Eclipse

Everything is ready now, import the project into Eclipse IDE.

In Eclipse menu, select “File“, “Import…“, “General” –> “Existing Project into Workspace“, select the project file path and import it.

Your project structure should look like this :

Eclipse import
project structure in Eclipse

6. Deploy to Tomcat

In Eclipse IDE, create a Tomcat instance, add the project and start it.

Tomcat instance
assign project to Tomcat

In Eclipse, review the console tab, make sure no error messages displayed, otherwise… send me an email :)

Done. Happy coding

    Should your example work on Jetty or tomcat launched by a MVN plugin? right?

      Yes, it should.

    I was trying to follow the above tutorial but getting this error:
