Examples of org.picocontainer.PicoCompositionException

org.picocontainer.PicoCompositionException
Subclass of {@link PicoException} that is thrown when there is:- a problem initializing the container - a cyclic dependency between components occurs. - problem adding a component - a request for a component that is ambiguous.
