Ok, the recent thread about using log4j as the default showed that there is a big interest in directly using log4j.
Sylvain raised the concern of performance which can imho be solved in the wrapper class. The avalon logging uses a wrapper class around the log4j logger to conform to the avalon Logger interface. This wrapper can store/cache the level in an instance variable making the test calls to isDebugEnabled() etc. as fast as possible. Although this is an optimization in the nano area which should neither increase/decrease performance for a complete Cocoon request, it should solve the concern. Now, imho only two questions remain :) 1. What should Cocoon offer to support log4j? So, everyone out there who wants to use/is using log4j with Cocoon, what are you missing? Examples could be, a support for configuring log4j via Cocoon etc. 2. Should we make log4j (with the improved wrapper idea from above) the default? WDYT?
