[Jenny]

Hi,

Anybody seen this error before? Could you help me figure out what's wrong? ClassA, ClassB, ClassC are not logging anything.

SLF4J: The following loggers will not work becasue they were created
SLF4J: during the default configuration phase of the underlying logging system.
SLF4J: See also http://www.slf4j.org/codes.html#substituteLogger
SLF4J: com.company.mycode.ClassA
SLF4J: com.company.mycode.ClassB
SLF4J: com.company.mycode.ClassC

thanks,
Jenny
