Hi Vincent,
You are probably not doing anything wrong and it most probably a log4j problem. In log4j 1.2 beta2 and earlier versions there was a serious compatibility problem where code compiled with log4j 1.1.3 would not run with log4j-1.2x.jar. However, the same code would compile and run fine if compiled with log4j 1.2x. This problem was corrected with log4j 1.2beta3. At least that is what I thought until now. My educated guess (still a guess) is that parts of your application are compiled using log4j 1.2X. Is it possible that the classes in WEB-INF/classes were compiled with log4j 1.2betaX? I would be very interested in the NoClassDefFoundError stack trace.
