If you are experiencing a problem, it can be informative to enable debug logging to allow the behaviour of the Client to be understood at a deeper level.

To do this, set the org.apache.qpid logger to DEBUG.

If you are using Apache Log4j with a log4j.properties file, this simply means adding (or changing) the following line:

      log4j.logger.org.apache.qpid=DEBUG
    

If you are using another logging framework, or you are using Log4j but configuring in another manner, refer to the documentation accompanying the logging framework for details of how to proceed.
