Eh, but you already have a getPort method without parameters:
You can use this method if you do not want to supply any WebServiceFeatures. If you have a compilation problem, then it may be related to a missing JAR, as you spoke about in another posting.
Also, editing generated classes is generally a bad idea. If you one day come back to modify your client and generate a new version of the generated classes, then any changes you hav emade by hand are lost.
