When troubleshooting workpoint functionality, if you enable log4j to DEBUG for the workpoint categories (like com.workpoint.queue.work.MailQWorker, or com.workpoint.*), there will be no DEBUG statements printed in the application server log.
The workpoint code has its logging statements configured at the INFO level. It contains no DEBUG level logging.
Do not set any of the workpoint loggers to DEBUG.
Instead, set the logging level to INFO to get all the available logging statements provided by Workpoint.
