Hi all Log4j/OSGi experts!
Yesterday I started to migrate from log4j to log4j2. I replaced all Log4j
1.x bundles with log4j-1.2-api as described here:
http://logging.apache.org/log4j/2.x/log4j-1.2-api/index.html
But I got following error:
Unresolved constraint in bundle MyBundle [21]: Unable to resolve 21.0:
missing requirement [21.0] osgi.wiring.package;
(&(osgi.wiring.package=org.apache.log4j)(version>=1.2.0)(!(version>=2.0.0)))
so...I checked the status of my OSGi-environment:
g! inspect cap * 11
org.apache.logging.log4j-1.2-api [11] provides:
-----------------------------------------------
osgi.wiring.bundle; org.apache.logging.log4j-1.2-api 2.0.0.beta8 [UNUSED]
osgi.wiring.host; org.apache.logging.log4j-1.2-api 2.0.0.beta8 [UNUSED]

As you can see logging.log4j-1.2-api doesn't export the log4j API 1.2. It
still requires log4j 1.2. So, replacing the JARs as described in the manual
does not work. Something is wrong. What can I do?
Thanks in advance!
Roland
