I am hoping someone can help me with this.  I am attempting to create the
client stubs for the WS-Notification spec provided by servicemix 

servicemix-3.1\deployables\serviceengines\servicemix-wsn2005\src\main\resources\org\apache\servicemix\wsn\notificationBroker.wsdl

(Note: To generate the notificationBroker.wsdl I deployed servicemix's wsn
example)

Running the wsgen task I receive the exception provided below (similar to  
http://www.nabble.com/problem-with-client-gen-from-wsdl-for-BookService-tf929892.html#a2431446
this post ).  I have used the command line version of wsgen and the ant
task, versions 1.2.4 and the latest from SVN.  Any idea as to what might be
causing this problem?
