Load an Applet from a Jar

**TechGate** · 25-02-2010

Hello
I am trying some applet program in java, I have a small question for you. How to execute an applet contained within an archive that is from the Jar file. I tried different things but I got nothing but was not successful. I think there should be one way to do this. If you have any idea about it then please let me know. Thanks in advance.

Hello,
You can try the following code for doing the same.

Code:

<html> <head> <title> app </ title> </ head> <hr>
<OBJECT
classid = "clsid: 8AD9C840-044E-11D1-B3E9-00805F499D93"
width = "100" height = "50" align = "baseline" codebase = "http://java.sun.com/products/plugin/1.2.2/jinstall-1_2_2-win.cab # version = 1,2, 2.0 ">
<PARAM NAME="code" VALUE="app.class">
<PARAM NAME="codebase" VALUE=".">
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.2.2">
<PARAM NAME ="archive" VALUE="app.jar">
<COMMENT>
<EMBED type = "application / x-java-applet; version = 1.2.2"
  width = "200" height = "200" align = "baseline"
  code = "app.class" codebase = "."
  archive = "app.jar"
pluginspage = "http://java.sun.com/products/plugin/1.2/plugin-install.html">
<NOEMBED>
</ COMMENT>

Hello,
Even I had the same problem and I also wanted an applet to run from a jar file. In fact I was already like that but the problem lay elsewhere. My build.xml changed somewhat the structure of my package so I did enjoyed my class Applet. So, first see that the class file is not changed by the other things which you are trying to perform in the code. Just be cool while doing the changes to your code because they effect the class file also.

Hello,
The simplest solution (in my opinion) is to build a bat file in which we place orders necessary to save the file in the bin directory of java sdk and run the bat file.
bat file example:

Code:

jar cf march.jar mapp.class

Simply retrieve the archive "march.jar" and place it in the web server directory.
To view the applet in a web page, you place the tags (at least) the following:

Code:

<applet code = "mapp.class" archive = "march.jar" width ="..." height ="..." codebase ="..." name = "mapp"> <param ...> </ applet>

It is no longer necessary to place the file "mappt.class" in the directory of the web server as it will be present in the jar archive. This allows to verify if it works.

Hello,
I tried the same, but I have the problem too. I am trying to load the applet from a jar file but it is not working.
Here is the code

import java.applet.Applet;


public class test extends Applet {
	/**
	 * 
	 */
	private static final long serid = 1L;

	public void init() {
		JOptionPane.showMessageDialog(null, "Hello, World!");
	}
}
