No - you have to reload the application or restart the JVM.

Re: Reloading the registry while running
Posted by belaran <be...@gmail.com>.
Sorry I mislead you. I'm not really try do this. I realised a study of
hivemind for the company i'm working in, and my boss ask me if I hivemind
registry could be reloaded. I was pretty sure it was not possible, but i ask
just to be sure...
Thanks for all your response

Well, if you're "upgrading", I would imagine that you're changing some code,
right? Are you using a servlet container which does auto-reloading of
classes when it sees that something has changed (like Tomcat)? Then, it
will reload the entire webapp and therefore the registry also.

yes i always can, but the point was more to upgrade an application while
it's running just by changing the registry... It's not really a good idea,
but i was just wandering if it's possible...

yes i always can, but the point was more to upgrade an application while
it's running just by changing the registry... It's not really a good idea,
but i was just wandering if it's possible...
