Running JAR by Browser

Question

I’m having a hard time figuring out how to do it:

What I Wish

I want to create a Google Chrome/Firefox extension that when I press a button in the html of my extension, it will run a file. JAR passing user settings parameter in the extension. So I thought about using JNLP.

Problem

But from what I understand of JNLP it executes the JAR directly from the server, and what I really wish is that it execute a JAR on the client’s machine this JAR will be already in a folder within the extension itself minhaExtensao/lib/foo.jar

Doubt

It would be possible to execute it so on the customer’s machine?

Answer 1

Take a look here http://java.sun.com/docs/books/tutorial/deployment/jar/run.html

I believe that just create as the example below in the html of your plugin.

<applet code=TicTacToe.class 
        archive="TicTacToe.jar"
        width=120 height=120>
        <param name="param1" value="value1">
        <param name="param2" value="value2">
</applet>

Take the test and put the results here, I’ll try to make one too.

Answer 2

The JNLP does not execute the code on the server, it is a protocol done exactly to allow the distribution of applications to clients (i.e., among other features, JNLP allows a client to download and run an application locally). I recommend the official tutorial from Oracle on Applet Deploy, as well as the way Deployment in-Depth. By the description of your requirements however I would go beyond an Applet, I believe you are looking for the Java Web Start and the infamous button (that can be replaced by any other image).
