It is a way to download and install and launch java applications via the web. Once you have JWS installed, you can launch ArgoUML by clicking on a link. You can also add an ArgoUML icon to your desktop. If you are using the JWS file for the "latest" stable or development release, you will automatically upgrade to new releases as they are made available. For more infomation, see the JavaWebStart product page.
How do I install JavaWebStart?

You can change your proxy settings for Web Start manually by starting the Application Manager and using the Preference panel. (Select File|Preferences to get there.)
