I get the erro message:"log4j:ERROR No appenders could be found for category (). log4j:ERROR Please initialize the log4j system properly." during configure log4 from a property file. It appears a Category without name, but I can't find such an animal in my configure file. When I turn on the configure debug, these two messages appear first but no other debug messages show such a "emptry" Category is parsed. Except this error, all of the named categories works fine. I use an extended Category simlilar with the AppserverCateogry in the deep extension example and have the line "log4j.categoryFactory=MyCategoryFactory" in the configure file. Anybody has good suggestion ?
