#23304 — Run a jar file on remote client machine?

I have a jar file that works well on my local machine, and does what I need it to do.  This jar file reads a directory of images and manipulates them and stores results in a separate directory.

I want to provide a web page to a client that will allow them to process data on their machine using my jar file and my web site / server.

How do I go about doing that?

You can deploy your JAR from your server to a client machine using 
Java Web Start: <http://stackoverflow.com/tags/java-web-start/info>

If that's not what you want, I don't understand the question.

Does that run the jar application in a window of the clients browser?
If so then yes that is what I want.

With Java Web Start, yes it does run in a window.  I believe you'll need 
a certificate to sign the app with however.

You don't need to sign the app if you're willing to have Java ask for 
confirmation before just about anything you do, e.g. to open a file. You 
do need to sign if you want all those verification steps to go away. 
Most people seem to want their JWS app to run with full permissions to 
do anything they want to the client machine.

I think what you're talking about requires using a special API.  If you 
use the normal one it just throws an error.  I'm assuming he doesn't 
want to re-code his app.

To be fair, that is only what every single garden variety program runs with
by default.

Right, but not necessarily in a window of the browser used to 
launch the .jnlp file.

A signed applet can do more, but I don't think it's _required_:

<http://docs.oracle.com/javase/tutorial/deployment/applet/security.html>

Here are some variations:

The OP says the application reads a directory on the local hard drive; 
he'll need permission of some sort for that.

I don't think we know yet if the JAR contains an applet or an 
application. A signed applet can access the local filesystem, but an 
unsigned application can request <all-permissions/>.

I habitually sign everything to detect tampering.

You have to get them to download and install it (perhaps using an
installer) Or you can put some Java WebStart around it, or you can
turn it into a signed or unsigned java Applet.

Motors make noise, and that tells you about the feelings and attitudes 
that went into it. Something was more important than sensory pleasure -- 
nobody would invent a chair or dish that smelled bad or that made horrible 
noises -- why were motors invented noisy? How could they possibly be 
considered complete or successful inventions with this glaring defect?
Unless, of course, the aggressive, hostile, assaultive sound actually served
to express some impulse of the owner.
