@udo: imo we should discuss the logging topic before we have a release which already uses slf4j - especially the suggestion of mario sounds interesting. regards, gerhard http://www.irian.at Your JSF powerhouse - JSF Consulting, Development and Courses in English and German Professional Support for Apache MyFaces 2009/6/5 Mario Ivankovits <ma...@ops.co.at> > Hi! > > > > Could one please eloberate a little bit more in detail what the pros are of > slf4j? > > > > Notice, I switched to it in our company project - but always using the > commons-logging api and just used the slf4j-over-cl wrapper.
