MC4J is a project to create management software for J2EE application servers and other Java applications. It is designed to utilize the JMX specification to connect to and introspect information within supported servers and applications. It provides the ability to browse existing managed beans (MBeans), update configurations, monitor operation and execute tasks.

This package realizes a typical behaviour found in many file-based conversations between independent systems: monitoring one or more local directories, observing incoming files and do something when they arrive.
