You will no doubt want to package and deploy your applet so that others can use it. You will need two things for this— a .jar file and a .htm (or .html) file.  The .htm file is something you must create.

 

Find .jar file. 

The .jar file is an archive that contains all necessary code to run the applet.  NetBeans has automatically created it for you. Navigate to the HelloWorldProject on your hard drive.  It will contain the folder dist. Inside this you will find HelloWorldProject.jar.  Copy (or move) this file to the folder that will contain your .htm file.

 

Create helloWorld.html. 

I recommend using my helloWorld.html file as a template. Right-click to download this file here and place is same folder as your .jar file.  Open with Notepad, WordPad, Word, etc. to change the settings to suit your project. If you’ve used all of the naming conventions that I’ve suggested, you should not have to change anything.  But if you do, the key line to alter follows.

<applet code="edu.usafa.helloworld.HelloWorldApplet" archive="HelloWorldProject.jar" width="400" height="300"></applet>

 

Let’s look at each piece of this line

• <applet> </applet> These are the tags that indicate that an applet will be placed here.
• code="edu.usafa.helloworld.HelloWorldApplet" The code attribute describes where the java class can be found.  Note that the first part of the attribute- edu.usafa.helloworld- is the package that you created when setting up your project.  The last part of the attribute-HelloWorldApplet-  corresponds to the java class that is created when compiling your project. In fact, you can replace this with HelloWorldApplet.class if you wish.
• width="400" describes the width of your applet.
• height="300" describes the height of your applet.
• archive="HelloWorldProject.jar" is the name of your .jar file.

 

If any of these are not correct, the applet may not run in your browser.
