Java Web Start and License Management -


can java web start integrate licensing management mechanism grab update if specific user licensed upgrades @ time?

so, let's user purchases software, downloads , runs it. authorized 1 year of upgrades. java web start automatically looks updates when start application, right? there way maintain user credentials during check after 1 year no longer allows them new version?

an easy way custom url locked local license file, guess shared. on server can have main controller looks @ url, looks support level , lists new jars or not depending on validity of user/ license.


another way use user name + authentication first identify user , license , app updates self downloading jars , have class launched, asks main app exit, copies jars , restarts main app.

so 1 of jars updater, called main app on start (if default short cut), updater update jars , call main app -no-update flag.
