Webstart first step

[Jos� Antonio Frutos]

I need distribute a java desktop applicatioon, but my application users have installed neither the jar nor java webstart. It's possible installed this on-line?.

As far as I know, you will need to have some version of Java installed on these client machines before your webstart application will be recognized and run.

Your browser needs to know what to do with the .jnlp files and it will only know this if java webstart is installed. You can specify the version of Java needed to run your application from the .jnlp file and this will be downloaded and installed as required, but you initially need a version of Java installed to begin with.

Cheers, Jared.

As far as I know, you do not need to have JRE in the client machine. You only need to specify the J2SE version in the .jnlp file and when the user clicks the link to the .jnlp file from his browser, it will check on his system whether the JRE is present or not, and if it is not, it will download it.

Do correct me if I am wrong, please..

You're right. But there might be a problem if the users do not have the rights needed to install things on the machine they use. We had a similar problem and had to roll out the appropriate JDK-version before things worked the way they should.
