WampServer is a bundle for web development for windows. It allows you run your own web server on your local machine. This is great because you can test all your web applications on your website and then upload it to your production environment.

In order to install WampServer on your machine, you need to do  the following:

  1. Visit the WampServer  website and click on the Start Using WAMPSERVER button.
  2. It will redirect you to this page

  16. Congratulations, you have successfully installed WAMP on your machine.
  17. Launch WampServer on your machine by leaving the check box and clicking finish.
  18. Launching WampServer  brings up the User Control. Agree to everything.

How to Add Java to Your Class Path

In the last tutorial. We installed the Java Development Kit on our machine. However, in this tutorial, we are going to modify our classpath.

If you look at the above image, you realize that the javac command doesn't work on command prompt. javac is the command use to instruct the computer to compile a Java program.

In order to set your class path in Java, you first need to right click on you computer icon on your desktop and go to Properties.

Select Advanced system settings. It will bring up a System Properties dialog box as shown below: 

Click on the Environment Variables button. It will bring up another pop up like this:

Create a new system variable called JAVA_HOME by clicking on the New button in the System variables section.
This is why I insisted on setting the installation directory to Java in the last tutorial. Click on OK. Now JAVA_HOME is now a system variable.

Scroll down the System variable area and find the path variable.

Click on the Edit button.
Add this to the end without editing anything -> ;%JAVA_HOME%\bin

Click the OK buttons on all the open dialogs.

To test if you are successful, run the javac command again. It should give you the following output:

Congratulations. You can now run Java programs on your machine.
