That was what I thought originally. But that isn't it... The jars we added definitely do not contain a log4j.jar, (I have checked the source and unzipped the jar files to be sure) and the only one in the workspace is log4j-1.2.15.jar in the lib folder of the EAR project. And all the jar manifests of the component projects point to lib/log4j-1.2.15.jar. We use IBM RAD7 and WebSphere 6.1.
