Subject: Initial ECM <-> OSGi bridge checked in
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

Hi all,

I committed an initial ECM <-> OSGi bridge in 
src/org/apache/cocoon/core/osgi.

This code is untested and there are still some pending points, but I 
wanted to share it ASAP so that we can discuss these issues.

What we have there is a ServiceManagerActivator that will create an 
ECM++. In this ECM, components that have exported="true" on their 
configuration are registered as OSGi services.

Also, the parent of this ECM is an OSGiServiceManager that looks up 
non-local components as OSGi services.

The ECM is given a LoggerManager that uses OSGi's LogService. We may 
consider using an optional LoggerManager service if present, as 
LogService has some limitations (no categories, and no isXxxEnabled 
methods).

The main pending point is the avalon context for the created ECM. Cocoon 
places a lot of environment-related information there that I currently 
don't know where to get from. Maybe this should be obtained from the 
Cocoon core bundle?

Sylvain
