The above is a complete example. If there is no Commons-logging.jar

If there is no Aopalliance.jar:

nested exception is java.lang.NoClassDefFoundError: org/aopalliance/aop/Advice

If there is no Aspectjweaver.jar

nested exception is java.lang.NoClassDefFoundError: org/aspectj/weaver/reflect/ReflectionWorld$ReflectionWorldException
