Re: Use log4j & commons-logging in bundle
Hi Thierry,
First of all, a bundle can only specify a single host bundle. So you
would have to decide which Bundle you want to attach to.
Rather - in the case of Log4J - I suggest you call the Log4J
configuration mechanism to control the configuration of Log4J.
Alternatively you might create your own Log4J bundle, where you control
the first use of Log4J and have the oportunity to configure Log4J
correctly.
Hope this helps.
Regards
Felix

shameless plug... you could also try Pax Logging :)
http://wiki.ops4j.org/confluence/x/F
for v0.9.5 and later you only need these two bundles:
http://repository.ops4j.org/maven2/org/ops4j/pax/logging/api
http://repository.ops4j.org/maven2/org/ops4j/pax/logging/service
and you can configure log4j using config admin
Hope this helps.
