Hi,
If my.jar is a swing UI app (or just a simple app), I'm wondering if
it's possible or how, that
this my.jar can be executed only once (no multi-session) in same
machine <or in same folder>?
Can any one tell?
In addition to the more traditional advice, if you happen to be
deploying your app with java webstart, you can achieve this
functionality easily. See
http://java.sun.com/j2se/1.5.0/docs/guide/javaws/jnlp/ and look up
SingeInstanceListener and SingleInstanceService.
