WSDLException: Can't find prefix for...

[Greg Cawthorn]

I am having a problem with a web service under Axis 1.1 in Tomcat 5. The 
service is a stub for a data handler and declares CRUD methods for a 
profile object which I have built custom serializers for and declared in 
my deployment descriptor. The interface looks like this:

   public void addNotificationProfile(VxsNotificationProfile profile) 
throws VxsPersistenceException;
   public void deleteNotificationProfile(VxsUserId userId) throws 
VxsPersistenceException;
   public VxsNotificationProfile retrieveNotificationProfile(VxsUserId 
userId) throws VxsPersistenceException;
   public void updateNotificationProfile(VxsNotificationProfile 
profile) throws VxsPersistenceException;

It deploys successfully but when I try to view the WSDL I get the 
following exception:

Fault - ; nested exception is: 
	WSDLException: faultCode=OTHER_ERROR: Can't find prefix for 'http://notification.voxsurf.com'. Namespace prefixes must be set on the Definition object using the addNamespace(...) method.: 

AxisFault
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode: 
faultString: WSDLException: faultCode=OTHER_ERROR: Can't find prefix for 'http://notification.voxsurf.com'. Namespace prefixes must be set on the Definition object using the addNamespace(...) method.: 
faultActor: 
faultNode: 
faultDetail: 

However if I remove some of the class's methods from the allowedMethods 
parameter in the wsdd (which I've attached), then I can view the WSDL 
with no error. It appears that I can declare a single method that takes 
a VxsNotificationProfile object as a parameter, but if I declare two 
methods such as addNotificationProfile and updateNotificationProfile 
then the error occurs. It may be a problem with my custom serializer for 
that class but the fact that I can view the WSDL for certain methods 
that take in or return an instance of the object suggests otherwise.

Does anyone have any ideas as to what I'm doing wrong?
Thanks
