public interface BeanCommon

Interface specifying routines that all weka beans should implement in order to allow the bean environment to exercise some control over the bean and also to allow the bean to excercise some control over connections. Beans may want to impose constraints in terms of the number of connections they will allow via a particular listener interface. Some beans may only want to be registered as a listener for a particular event type with only one source, or perhaps a limited number of sources.
