COntrolling an osgi server from ant [message #87841]

I have an ant script that will download new versions of plugins as they
get compiled on our CruiseControl system and install then into the
plugins directory on our OSGi server. How do I tell the OSGi server to
reload the new plugins?

Also just restarting the server would be acceptable also.

If this is not the correct way to handle the server start/stop/reload
please advise of the correct way.

OSGi provides good support for installing and uninstalling bundles in a live
system however for what you're doing it sounds like a restart would be the
easiest way. You might want to look at using "-clean" as a command argument
to clear out your old configuration data each time you run.

Simon thanks for the information :->. What is the best way to shut down
the server in an automated fashion? I want my ant script to be able to
kill the running server. Should I just run a kill with sigterm or is
there a better way to kill the running server?

SIGTERM is not pretty but would work -- especially if you're in a position
to recreate your installation.

Ideally you would want to follow the "close" console command logic and call
EclipseStarter.shutdown when you want to stop.
You might try doing something clever with a shutdown handler or else find
some other means to signal the process.

You could also have it running with a network console (e.g. -console 1234) and then use Ant to telnet in and echo 'shutdown\n' to bring the system down remotely.

Also see http://www.eclipsezone.com/eclipse/forums/t93976.html which talks about how to get a Java app booting up an Equinox OSGi runtime.

Mark,

I had this exact same issue. The solution I came to that worked
nicely was to write a simple bundle that scans a directory
(/cruisecontrol/artifact/project..) for bundles. When it finds a
bundle, it loads it, looks for existing bundles with older versions, and
if finds them uninstalls them, then starts the new version. This meant
that the latest build versions of my bundles were always available for
tests. I would be happy to give you the source if interested.

cheers
ken

Sounds a little bit like Peter's fileinstall agent.

I like the idea. Perhaps an implementation specific version could handle
restarts when necessary.

Oh, cool. I wish I'd seen this earlier. :) The only difference I can
see from reading the short description on the referenced page is the
version handling. Although that could probably be just as easily
handled at the filesystem level...
