Hi All,
I'm going to back up a little bit, so I can address Petia's
original request most effectively...i.e. running ECF remote
services on Apache Karaf.
1) Although I haven't yet done it myself, according to docs [1],
Karaf can be used with both Apache Felix and with Equinox.
Given this, ECF remote services can certainly run on the Equinox
instance of Karaf...since we run on Equinox all the time (i.e.
in Eclipse, test code, server instances of Equinox + ECF, etc).
If Petria (and/or others) uses the Equinox-based instance of
Karaf, then the answer to the initial question of will ECF
remote services run on Karaf is an unqualified 'yes'. We
haven't (as yet) created a distribution of ECF remote services
specifically for Karaf/Equinox, but this is certainly something
that we could do...given sufficient resource availability. If
there is interest in us doing this, please open an enhancement
to that effect [2].
In the mean time, there are some example product configurations
that contain information about the full extent of dependencies
for ECF Remote Services/Remote Service Admin...on simple
servers. For example, see the product configurations here
[3]. I understand that this isn't ideal, but it is what we
have at the moment (see the <plugins> section).
I've also created a new documentation bug [4]...for specifically
documenting the ECF RS/RSA dependency structure, so that
consumers of different parts of ECF remote services (e.g.
different discovery and/or distribution providers), can easily
determine what other dependencies are required...on which
framework. Please add yourself to this bug if you are either
interested in receiving this documentation and/or willing to
participate in it's creation (help wanted).
2) About ECF and Felix. Months ago, Markus created a
configuration and ran the ECF remote services/RSA examples on a
previous version of Apache Felix. To do this, he not only
installed the ECF RS/RSA bundles, he also installed on Felix the
necessary Equinox-specific bundles (e.g.
org.eclipse.equinox.concurrent,
org.eclipse.equinox.common...which contains
org.eclipse.core.runtime, Equinox event, etc).
At that time, and with the necessary parts, Felix was running
ECF remote services just fine. I don't expect that to be any
different now (i.e. I don't expect that Felix has introduced any
incompatibilities, ECF hasn't done so, and I don't think that
Equinox has introduced any incompatibilities in the required
bundles/packages/classes)...but I don't know for sure, as I
haven't run ECF RS/RSA on Felix recently.
At that time, I believe that Markus also created a maven repo
that contained ECF remote services...and the necessary
dependencies for running RS/RSA on Felix. All of the build
scripts for doing this are located here [5]. The maven repo is
here [5a].
Also...Markus created a script for running ECF on Felix using
pax runner. These scripts are located here [6].
So...although it's possible that ECF RS/RSA won't run on recent
version of Felix (because of some incompatibility introduced by
Equinox, us, or Felix)...I don't expect that to be the case
(i.e. I expect ECF RS/RSA to work on Felix)...and so I also
expect that ECF RS/RSA on Karaf/Felix would also work fine. If
it doesn't for some reason (that's under our/ECF's control) we
can/could certainly address it.
That's my (Scott) understanding of things. I wasn't aware of
Karaf until recently, but I would like to move toward creating a
distribution of ECF remote services specifically for Karaf...in
order to make it easy for Karaf users (of either Felix or
Equinox stripe) to use ECF remote services (of whatever provider
configuration). If others are able/willing to contribute to
this then let's get it started.
Thanks,
Scott
