/**
* TopLink 9.0.4 SessionLog implementation that logs through Commons Logging.
*
* The namespace used is "oracle.toplink.session". Fine-grained filtering
* of log messages, for example through Log4J configuration, is not
* available on TopLink 9.0.4: Consider upgrading to TopLink 10.1.3 and
* using the CommonsLoggingSessionLog class instead.
*
*
TopLink log entries with exceptions are logged at CL WARN level,
* TopLink debug log entries at CL TRACE level, and any other log entry
* at CL DEBUG level. Finer-grained mapping to log levels is unfortunately
* not possible on TopLink 9.0.4.
*
*
Note: This implementation will only actually work on TopLink 9.0.4,
* as it is built against TopLink's old SessionLog facilities in the
* oracle.toplink.sessions package, which are effectively
* obsolete (deprecated and bypassed) as of TopLink 10.1.3.
