Off-the-shelf Standalone App Framework?

Hello all,
    I'm new to excalibur and co. and am still reading
through the
available documentation. However, having read through the
main pages,
I still have not found what I'm looking for... maybe someone
on this
list can point me in the right direction?

    I'm looking for a relatively lightweight java
application
framework that supports COP, IoC, but also can run as a
standalone
application (i.e. with bootstrapping, start/stop scripts
etc)

    The part that is so far missing is the bootstrapping
mechanism.
Before I head out and write my own, I wanted to make sure I
haven't
skipped over some existing thing...

Excalibur? Phoenix? Merlin? Keel? Metro? Spring? so many
products that
seem to want to do the same thing... almost.

Thanks!
W.

Hello John,
  Thanks for your answer.
How do you shutdown the app? do you ctrl-c (or kill)? or do
you use an
excalibur specific "shutdown" mechanism (through
an admin console)?

We just call system.exit().

Hello all,
    Thank you for all your answers... After doing some more
extensive
"web-gardening", I believe I have found the answer
to my prayers: the
Spring Application Server (http://www.abstra
cthorizon.org/sas/).
    It has the module-based features, plus the wrapper
scripts that
make it work out of the box.
Let's hope it meets expectations

Hope it works out.  

Did you consider OSGi?  Apache Felix or Eclipse Equinox
would probably
provide everything you need.

I did consider OSGi, I must admit I hadn't looked at Felix
yet, I've
just downloaded it and am trying it out.
I've already developed for the Eclipse framework and it's
great for
gui-based apps, dunno if it fits well as a server-side
application
(any thoughts on this?)

Though Eclipse is built on OSGi, it's easy to never see it
or know it
if you develop plugins.  That said, you can easily create a
headless
Eclipse application that runs as a service.  You just don't
import any
of the Workbench, but you still get to use the extension
APIs and
updater and all the other non-UI Eclipse features.  That
includes the
Eclipse launcher.  I've written a headless Eclipse
application and it
wasn't difficult.

Though now I favor pure OSGi applications.  You can use
Eclipse
Equinox or Apache Felix as your OSGi container.  You'll find
plenty of
arguments for either project.
