It would be very nice to have a "hot deploy" facility for plugins and
new versions of plugins already deployed..... is it available/feasible?

Thanks,
Sandro

I don't think anyone has implemented this yet. This was one of the most
interesting feature I found in JBoss - deploy by copying.

The update manager is capable of installing plug-ins while Eclipse is
running. Not all plug-ins are good citizens in a dynamic environment
(for example, the Eclipse IDE plug-ins), so the degree of success will
depend on the plug-ins involved.

The only thing missing (if this is what you meant by hot-deploy) is a
something that monitors the local sites (the main "plugins" directory
and any extension locations the Update Manager knows about), detecting
changes/addditions/deletions and taking the right actions accordingly.
Not sure whether Update provides API for changing the platform
configuration.

Or if you are *not* running with Update, you can go straight to the OSGi
API.

My customer will run some of the user base in a Citrix environment, so
I'm implementing a sort of "hot deploy" to allow the users to pick up
changes and additions to the local site (the application knows wich
plugins can be dynamically updated).

Yes, I can:
- easily detect that the local site is not up-to-date with the file system
- easily install/activate the changes using OSGI API
BUT:
I have not yet found any clean way to change the local site configuration.
As a result, the same changes are picked up at each refresh cycle.

Any suggestion?
Thanks,
Sandro

The only clean I know is the configuration API:

Thanks.
Actually I overlooked this API because I was trying to use "higher
level" APIs.....i.e. InstallOperation or
ReplaceFeatureVersionOperation.... this operations update the LocalSite
info AND the PlatformConfiguration (and provide some commit/rollback).
It appears that directly using PlatformConfiguration API will leave
LocalSite info outdated..... but maybe this will not be a problem.... I
will try.

Best regards,
Sandro
