Avoiding multiple instances of a same application

[Maneesh]

Hi,

I have a java application and I want to make sure that there gets just
one instance executed (on the same machine).
Can any one suggest me some approach to do the same.

Thanks
Maneesh

Good approach, the socket. While I have your attention,
do you have any ideas that might suit an unsigned applet?

I have been wracking my brain, but nothing I can think of
might work for applets that are not (necessarily) running
under the same VM/AppletContext.

Hi Andrew,

That's exactly, what Applets are designed to: to run in a sandbox and be
unaware of everything outside the sandbox - of course even of an other
Applet that runs in another Sandbox (or, by the way, even of the
existance of another sandbox on the same computer).

The Applet has to be signed.

By the way, I think, webstart is in almost any case a better solution
than an applet.

Ciao,

You can use Webstart for applets.
