JNLP and Java Web Start

[mitrship gupta]

hi to all
as i know java web start installs automatically with jre 1.5. but for earlier version u have to seperately install java web start.
i have a developed application using jnlp. now wht will happen if i run this applciation on machine on which jre1.3 is installed but not java web start???
is there any way i can ensure my application runs on any machine with jre installed???
can i make my application download and install java web start if its not available on comp??
thanks in advance

It installs as standard with 1.4 too, but 1.3 may be a problem like you say.

I suspect nothing will happen. The machine won't know that this file should be launched with webstart because webstart is not installed.

A tough situation to be in. You need some kind of webstart installed in order to get an application running or installed through a .jnlp file.

Maybe others have some suggestions.

Cheers, Jared.

detect the browser
run java web start dedection script(browser dependent)
install if not

Cool. Can you post the script in a 'code' block so that we can all see for future reference?

Cheers, Jared.

Instructions on detecting the presence of WebStart are available on Sun's page:

http://java.sun.com/j2se/1.5.0/docs/guide/javaws/developersguide/launch.html

That script seems good at detecting whether WebStart is installed or not. I'm not sure I like their instructions on how to auto-install WebStart if it isn't installed.

Hi,

Thanks for the link. I'll check it out sometime.
