As far as I know when the user clicks a WebStart link on a webpage then (at first) only a *.jnlp file is delivered to the local computer resp. the browser.
Afterwards it is oftentimes described that
1. An appropriate JRE environment is launched from the local computer
2. a *.jar file (with the actual application) is retrieved from remote web server and started within the local J2SE environment.
Some related questions about this scenario:
1.) Can I load a JRE environment from another, local inhouse network drive/computer instead of the local computer?
2.) Can I load the *.jar file from another, local inhouse network drive/computer instead of the remote (Internet) server?
3.) The application *.jar is put into the browsers cache.
Assume the network connection is broken after the first successful download. Can I start the WebStart application out of the browsers cache anyway or is a running
network connection absolutely required for each start?
