Logging in Team Concert plugin

Hi,

We are developing a plugin for CCM.

Right now, we are using apache-commons-logging api for logging, but to get it working on tomcat, we have to modify ccm's log4j.properties file (%SERVER%/conf/ccm/log4j.properties). Can we do it by providing our own log4j.properties file inside plugin?
We tried it just by including log4j.properties and log4j.jar inside plugin's main jar archive, but it didn't worked.

Anyone know how to do that?

Thanks in advance,
KW
