    It is stating that a log4j class is missing.  Make sure you have the necessary log4j jar files in your WEB-INF/lib directory.

    Thanks Brian but the files are already exists. i have changed web modules(classes loaded with local class loaded first (parent last) as well.

    Caused by: java.lang.IllegalStateException: Detected both log4j-over-slf4j.jar AND slf4j-log4j12.jar on the class path, preempting StackOverflowError. See also http://www.slf4j.org/codes.html#log4jDelegationLoop for more details.

    FYI ..log4j-1.2.16.jar, log4j-over-slf4j-1.6.1.jar, slf4j-log4j12-1.6.4.jar
