I did take a look into this when I was trying the hot deploy exercise. My understanding is, this is property which felix file-install internally uses to perform hot deploy. It polls the "deploy" directory and installs any newly found bundle, uninstalls when the bundle is reomoved.
What I'm trying to figure looks a little beyond the scope of felix file install. If you recall yesterday's discussion on hot deploy of a different version of a bundle (for/bar example), I tried few things and understood the behaviour. To refresh, my container has foo-1.0.0 which has a dependency on bar-1.0.0. Successful, hot deploying a bar-1.1.0 requires the following step. 1. Drop the bar-1.1.0 in deploy folder. Felix file install poller will pick it up and install it. 2. Uninstall bar-1.0.0 from the container 3. Refresh foo-1.0.0. so that it'll refer to bar-1.1.0 The part which I'm struggling is to deal with step 2 and 3. I don't think felix file install allows you to do so. Doing it through web console is an option, but I was more looking into an external script which can do perform the above steps by calling some API / script provided by OSGi / felix. Another thing I've noticed is OSGi core framework Bundle interface provides the lifecycle methods. Maybe, I can create a bundle, expose a service which will use this API to perform the lifecycle operations. The referenced bundle lists, which needs to be refreshed, can be automated through spring app context. This prompted me to post the question to understand what's the best practise being followed in this particular aspect. -Thanks On Wed, Jun 29, 2011 at 11:53 AM, Richard S.
