How to create JNLP file for a java web application?

Question

I have a java program that I ultimately want to deploy it on the web.

I started off creating a jar file from bunch of classes:

jar cfe tbi.jar trail1modified trail1modified.class InitialKeypad.class InitialKeypad$1.class InitialKeypad$2.class InitialKeypad$thehandler.class InitialKeypad$thehandler2.class InitialKeypad$thehandler3.class InitialKeypad$thehandler4.class Keypad5$1.class Keypad5$thehandler.class Keypad5$thehandler2.class Keypad5$thehandler3.class Keypad5.class Keypad6$1.class Keypad6$thehandler.class Keypad6$thehandler2.class Keypad6$thehandler3.class Keypad6.class Keypad7$1.class Keypad7$thehandler.class Keypad7$thehandler2.class Keypad7$thehandler3.class Keypad7.class Keypad8$1.class Keypad8$thehandler.class Keypad8$thehandler2.class Keypad8$thehandler3.class Keypad8.class Keypad9$1.class Keypad9$thehandler.class Keypad9$thehandler2.class Keypad9$thehandler3.class Keypad9.class Keypad10$1.class Keypad10$thehandler.class Keypad10$thehandler2.class Keypad10$thehandler3.class Keypad10.class Keypad11$1.class Keypad11$thehandler.class Keypad11$thehandler2.class Keypad11$thehandler3.class Keypad11.class Keypad12$1.class Keypad12$thehandler.class Keypad12$thehandler2.class Keypad12$thehandler3.class Keypad12.class Keypad13$1.class Keypad13$thehandler.class Keypad13$thehandler2.class Keypad13$thehandler3.class Keypad13$thehandler4.class Keypad13.class Keypad14$1.class Keypad14$thehandler.class Keypad14$thehandler2.class Keypad14$thehandler3.class Keypad14$thehandler4.class Keypad14.class ReKeypad.class ReKeypad$1.class ReKeypad$2.class ReKeypad$thehandler.class ReKeypad$thehandler2.class ReKeypad$thehandler3.class ReKeypad$thehandler4.class time.class time2.class trail2$1.class trail2$2.class trail2.class UO$1.class UO$2.class UO$thehandler.class UO$thehandler2.class UO$thehandler3.class UO.class

Now I wish to create a JNLP file. I am following this http://download.oracle.com/javase/tutorial/deployment/webstart/deploying.html

I am bit lost on the JNLP part. How do I create it? And what does it signifies? Are there any tutoring videos on (for example) creating a simple Hello World program --> jar file --> JNLP file --> HTML stage --> java web application.

Answer 1

A brief Description:

Java Web Start is a mechanism for program delivery through a standard Web server. Typically initiated through the browser, these programs are deployed to the client and executed outside the scope of the browser. Once deployed, the programs do not need to be downloaded again, and they can automatically download updates on startup without requiring the user to go through the whole installation process again

Look at this. This includes the simplest and comapct steps to create a jnlp file.
