New Revision: 17822

Modified:
   labs/jbosstm/workspace/adinn/XTSGF/WSTX/classes/com/arjuna/mwlabs/wst/at/ContextFactoryWSImple.java
Log:
modified so that the W3CEndpoiintReference WSDL metadata is supplied by hand but to no avail since the metadata is ignored when the W3CEndpoiintReference is processed under getPort()
