Spring DM - Logging Configuration Problem
Hi,
i try to migrate an existing spring application to osgi and spring dm.
When i start the application i get the stack-trace, listed below.
It seems that the osgi.extender can not create the applicationi context due to an error in the
logging configuration. I added the slf4j (version 1.5.11) plugins "org.slf4j.log4j", "org.slf4j.jcl" and "org.slf4j.api",
to use slf4j on top of log4j.
The log4j properties file is bundled in a fragment, that is assigned to the log4j plugin.
Obviously the osgi.extender tries to run the apache commons logger instead of slf4j.
What have i missed.
- is it necessary to start the logging bundles explicitly (via the config.ini) before the osgi.extender is startet?
- where do i place the log4j.properties file to make it accessible for the osgi.extender?
- is there any further configuration necessary, to get the log-system running?
Any help would be much appreciated.
Thanks
