JAX-WS multiple implemetations of 1 endpoint interface

[John Landon]

Hi,
I am using JAX-WS for my web service.
Now I need to have multiple implementations of the endpoint interface. Let's say 1 implementation will return array of numbers and the other one will return array of strings. The interface has only 1 method

Object getData(Object input)

.
Both clients want to access the same url (not by the implementations but by the endpoint interface) but each client want to receive a different array.
How do I configure this (probably in sun-jaxws.xml)? How each time the server knows what implementation to use?

Thanks.
