Steps for Java Web Start

1. Make jar file of your class files and resources like icons, images etc. using following command:

   jar cf JarFileToCreate.jar abc.class def.class ...

   For More details on creating Jar files, see create-jar-file-for-java-app
2. Make jnlp extension text file with following information:

   <?xml version="1.0" encoding="UTF-8"?>
   <jnlp spec="1.0+" codebase="http://localhost/jnlp" href="MyApp.jnlp">
       <information>
           <title>My App Title</title>
           <vendor>MonishVendor</vendor>
       </information>
       <resources>
           <!-- Application Resources -->
           <j2se version="1.6+" href="http://java.sun.com/products/autodl/j2se"/>
           <jar href="TestApp.jar" main="true" />
   
       </resources>
       <application-desc
            name="DemoName"
            main-class="GUI_QPDownloader"
            width="300"
            height="300">
        </application-desc>
        <update check="background"/>
   </jnlp> 

3. That's all. Now run jnlp file from any web-browser to test
