let's talk about OSGi Framework which we want to use

[kimby...@gmail.com]

First of all, we should concentrate on OSGi framework. We should know
about this framework. What reference is available and what reference
implementations are available ?
Anyone knows about this framework, please share your information.

And then, i know there are several reference implementations on OSGi
standard. Which one is appropriate to our purpose ?

There are a few available documents about OSGi and
almost in OSGi Official Documents Page - http://www.osgi.org/documents/

Now, only 3 OSGi implementations are certified as OSGi R4.
But 2 implementaions are commercial and embedded-oriented things,
only one implementation, equinox from Eclipse, is open-source and
generic implementation.

And there are some famous open-source implmentations - Apache Felix,
Knoplerfish.
It is natural that we should use open-source one.
Another important point that we should consider is OSGi service
supports.
So I recommend equinox, because it is open-source project and supported
by IBM.
But I heard that Knoplerfish is also very active project,

Let's try some implementations, then choose which one we will use.
I think we should make the compatible services with all OSGi
implementation. ;-)

Oops, knopflerfish (pro) is also one of the certifed R4
implementations.
: Prosyst, Equinox, Knopflerfish(Gatespace)

I thought that Gatespace and Knopflerfish are different ones.
