How to do logging in a server-site plugin?

Hi,

I created a server-site plugin that sends a Http message whenever a workitem is saved. Due to problems on the receiver site I would like to log several details from the plugin processing. How can I do that?

I created a log4j.logger (my class is named "com.ibm.rationalcoc.workitem.followup.service.BuildOnStateChangeParticipant")

private static org.apache.log4j.Logger logger = org.apache.log4j.Logger.getLogger(BuildOnStateChangeParticipant.class);

and added following entries to the ccm log4j.properties :

log4j.logger.com.ibm.rationalcoc=DEBUG
com.ibm.rationalcoc=DEBUG

Which of these statements is correct? Is the log4j properties file in /server/conf/ccm the correct place for logger definitions within a RTC plugin?
