Obviousely it's because of the Log4j, I'd like to use from my WEB-INF/lib directory: | Caused by: org.apache.commons.logging.LogConfigurationException: User-specified log class 'org.apache.commons.logging.impl.Log4JLogger' cannot be found or is not useable. | at org.apache.commons.logging.impl.LogFactoryImpl.discoverLogImplementation(LogFactoryImpl.java:798) That's all is very confusing.
