WSIFCorrelationServiceLocator is a helper class for locating
the WSIFCorrelationService. This may either be the WSIF provided
WSIFDefaultCorrelationService, or, when running in a managed
container the container may provide its own implementation which
this will locate by doing a JNDI lookup.

with a JNDI lookup for "java:comp/wsif/WSIFCorrelationService",
if that fails then the WSIFDefaultCorrelationService is returned.
