Re: Is there a "Push" technology for (entry) fields? Force fileds to be updated from server possible?

Assume I start a java app whose GUI contains a couple of entry fields (and labels).
Initially I can fill these entry fields (resp. labels) with some values.

Once the GUI dialog is displayed the user is normally able to enter something else.
But AFAIK the content values can NOT be updated by the prgm resp. a remote server AFTER the display.

Maybe there is a trick to update it anyway.
In former Java versions this "Push" technology was not possible.
But iI could imagine that the newer Java version contain meanwhile this "Push" feature.

How do I do this?

If you want an event on the server to update a Web app, I believe something called Comet (an extension of Ajax) can do this. It depends on having a persistent connection. See
