I have another question regarding Lists being the returned class. I have been able to get a List of strings being returned from my webservice and it is working fine. What if I have a List of User objects being returned from the webservice. User is a java class I have written. How does Axis send me this List object. Do I have to write a serializer or deserializer for the User class.
Any help is greatly appreciated.
