Description

I have problems while loading log4j.xml configuration file in osgi environment.

I have the following started equinox container:

+--------------------------------------------------------------------------------------------------------------------------------

osgi> ss log4j

Framework is launched.

id State Bundle

58 RESOLVED my.log4j.xml.fragment

Master=136

136 RESOLVED org.apache.commons.log4j-api_2.0.0.beta3

Fragments=58

137 RESOLVED org.apache.commons.log4j-core_2.0.0.beta3 +--------------------------------------------------------------------------------------------------------------------------------

The log4j2 config file is packaged under my.log4j.xml.fragment.jar/log4j.xml.

If I have the upper bundle-configuration

• than the following output happens:

+--------------------------------------------------------------------------------------------------------------------------------

ERROR StatusLogger Unable to locate a logging implementation, using SimpleLogger

FATAL Log4j_2 log4j-2.0.x logging

ERROR Log4j_2 log4j-2.0.x logging +--------------------------------------------------------------------------------------------------------------------------------

QUICKFIX If I update the org.apache.commons.log4j-core_2.0.0.beta3.jar!/META-INF/MANIFEST.MF

• append: Fragment-Host: org.apache.commons.log4j-api
• than log4j2 configuration is loaded and work.
