Hi Stuart,
Thanks...this is great. Just for my and others info, how much code is pax?
For the time being my trivial class is just 2500 bytes, so as 'last
ditch' (i.e. if pax or no others are available) it works OK but having
something like pax as part of equinox impl would be nice.

Thanks Niclas.
I'm really looking for something much more trivial than Pax
logging :)...so for the time being I implemented LogService myself.
But thanks for the info, I may very well use Pax logging in the
future.
One question: what does the Pax logging API bundle depend upon?
(i.e. extension registry?, others?).
The Pax-Logging API bundle only has dependencies on the execution
environment (ie. it needs
the javax.xml.parsers and org.w3c.dom packages) and on the OSGi
framework itself (only the
org.osgi.framework, org.osgi.service.event and org.osgi.util.tracker
packages).
It uses the OSGi service registry, rather than the Eclipse extension
registry.

Equinox in its purest form has no bundles in it besides the system bundle, and
IIRC the internal Equinox logger is not exposed.
That is, is there some basic LogService that can be used as a last-ditch
logging mechanism (if no other LogService is available)?
Pax Logging attempts to provide both OSGi Log Service functionality as well as
bridging of third-party legacy APIs such as;
JDK Logging
Log4J
Jakarta Commons Logging
Avalon Logging API
SLF4J
KnopflerFish Log
Pax Logging consists of 2 bundles. The API bundle must always be present and
is what all the legacy code will 'bind' into when they lookup a logger the
respective way. The Service bundle can come and go to allow for upgrade of
the Log4J driven bakend, without taking down the entire application.
When the Service is not available, the API will revert to System.out (a
buffering version is under construction).
You find Pax Logging at OPS4J,
