Network license control for a Java application

Show all headers | View raw

I have been tasked with providing some form of network license control for a 
Java application.  The app would be stored on a network drive and run from a 
client machine.  The basic idea is that it will be able to work out how many 
times it is being run concurrently and prevent the N+1th user from running 
the software where N is the number of concurrent licenses the customer has 
purchased.

Is this possible somehow with a Java application?  I was thinking of maybe 
incrementing a number stored in a file every time the app is run and then 
decrementing it again when the app exits.  I also thought of storing a time 
when each app invocation started so I could "time-out" users in the cases 
where the app may crash.

Is this a viable solution or is there a better way?
