 I don't really understand how its going to run.

I've also puzzled over this.  I've figured out that you can point
pax-runner at the hello.composite file.

I'd love to see a tutorial on how experienced OSGI developers set up
their the development environment, and how they work the
edit/compile/redeploy cycle.  It's very obvious for mvn jetty:run
(just wait for the scanner, or use JavaRebel).  It's not so obvious
how people work with OSGI containers.  The best I've figured is to use
the pax assembly: stuff to point at target classes, and run update
bundle-id for each edit/compile cycle - it's a bit clunky.

Any offers/suggestions?  (Sorry, I realise the question more about
OSGI than lift)

Re: [Lift] OSGi example, what to do to make it run?

2010-02-05 Thread Heiko Seeberger
OK ;-)

This is what I answered to Martin so far:

 I do not know such a tutorial, sorry. OSGi offers hot deployment out of
 the box, hence you do not need any JRebel or so. But by default (according
 to the spec) each bundle must be a JAR, hence you need a full build cycle.
 Eclipse Equinox allows for hosted deployment of usual PDE projects.


Currently Lift's OSGi support is constrained to single bundle (module)
applications. Of course this is already beneficial, because all the
dependencies (including lift-webkit etc.) are deployed as separate modules
and therefore can be updated separately. Also it should be possible to
deploy different Lift apps to one OSGi container.

But on the long run I would like to see real modular Lift applications:
Where one Lift app is made up from several bundles. Maybe some of them are
installed later and contribute to the menus, the mapper etc.

OSGi and JEE integration, namely web app integration, has been quiet for
some time, but recently there seems to be some process. I am not sure
whether the spec will deal with composite web apps: If not, we could pioneer
in this field.

Any ideas or questions?

Philip,

Good to see some interest in Lift's OSGi support!

Of course Lift will need a servlet container. Hence you will have to
install one in your OSGi framework, too. The same accounts for all the
dependencies, e.g. the Scala library.
