Hey all, I was wondering if anyone has written up any thoughts on best-practices for deploying apps based on Felix/OSGi and for updating/deploying a set of bundles?
Along with some issues withs updating our bundles, I'm trying to work out the best of automated, or making easier updating a system with multiple bundles (we only have 5 so far, but its already showing some growing pains (which could just be misunderstandings on my part)). Currently I have a custom Felix launcher that starts a JNDI server outside of OSGi (Objectweb's Carol) which I was having all manner of pain getting it to start/stop from a bundle, along with all manner of class loading issues, but then I also have a block of code in my launcher which installs the 10 or so bundles we have (5 of our own, 5 standard ones). I've had a look at the Felix File-install bundle which worked well, other than starting bundles in random orders (not really a big issue, but seemed to annoy some of the devs due to seemingly random changing behaviour). I understand the new Spring OSGi server contains some form of "bundle of bundles" setup (an uber jar), is there anything similar for Felix? I think at its core, I think I'm looking for some form of dependency tree in my bundles, so that when I stop/update bundle X, bundles Y and Z stop, then restart aswell (and maybe optionally attempt to update themseves as well). I'm almost thinking it'd be easier to rework my app so its pretty much just one huge uber-bundle, but I like the small bundles...
