Richard, Thanks for the response. Yes I have read the document listed below and it has been of great value in getting us going.
I did not think it would be possible to get the service up front, but figured it was worth inquiring. I thought about using the ServiceListener as that is how I see the Logger implemented it in the org.apache.felix.framework package. But, after re-reading the section on "Using Services Provided by Bundles", I guess that is a better approach. If there are multiple loggers and I implemented it using the ServiceListener then I would potentially only get the last provider of the service. Not necessarily the desired result. Not sure just how best to address this since I would ideally like a common logger out of the gate. Oh well I will give it some thought. As always, thanks for the assistance.

There is no way to get a service "up front" since there is not necessarily a service there to get. If you want to make sure you have a log service before any other bundle starts, you can deploy the log service into a lower start level than every other bundle... Also, since you likely don't want to include the log service interfaces on your class path, you might want to investigate using reflection to access the log service. -> richard Todd Nist wrote: > When embedding Felix what is the best way to get hold of the Log > Service?
