    Hi

    I have a small problem :p . Beacuse i need to create JPA layer for all .war
    files i put a lib with it into the main lib directory of a tomcat. The
    problem is witch apache commons logging :(

    Caused by: org.apache.commons.logging.LogConfigurationException: Invalid
    class loader hierarchy. You have more than one version of
    'org.apache.commons.logging.Log' visible, which is not allowed.

    With toplink i have no problem beacuse it uses log4j direclty without
    commons . How can i make it run ???
