Eclipse ECF Vs Apache CXF

I'm trying to come up with an architecture which allows me to have OSGi bundles distribut开发者_运维技巧ed remotely which get discovered dynamically etc.

After some time spent looking at what's out there I am oriented at using the following:

• Apache CXF (as OSGi Remote Services implementation)
• Spring Dynamic Modules
• JAX-WS Tools Component for Eclipse

One of the things I was trying to understand is where projects like Eclipse ECF and Riena stand in this regard. Are they alternatives to Apache CXF? (In this case which one would you suggest? What are pros and cons?) Do they wrap CXF? (In this case what is they add?)

Thanks in advance, Matteo

ECF a complete implementation of the RemoteServiceAdmin spec from OSGi 4.2, the CXF is currently being refactored to be compliant with the spec but is still valid distributed OSGi (the spec just mandates how they're to be managed, the key distribution stuff (what parameter to add to your service properties to make it remotable, etc).

ECF was, until recently, an Equinox only rOSGi implementation, but dependencies have been fixed and it should deploy onto Felix, Knopplerfish, etc with no problems.

ECF has a pluggable transport layer, see http://wiki.eclipse.org/ECF_Providers for more info (some providers clearly aren't applicable for distributed services). CXF comes from a webservices background, but has support for more performant means of distributing services too.

There was some talk about getting Riena to use ECF, not sure how that's gone.

If you've got the cash Paramus offer a very nice solution (http://www.paremus.com)

I don't like webservices so am somewhat bias towards CXF, also ECF is compliant (so you can move to another implementation later with no problems) and pluggable (so you could always write your own transport provider). If it were my call, and I had the cash I go with Paramus otherwise ECF.

UPDATE EDIT: I've just recently started playing with FuseSource Fabric, it's very nice (we're already using Camel with Karaf, so it dovetails there nicely). The RemoteServiceAdmin running over HawtDispatch is apparently very very fast.
