overloaded operation names in JAX-WS

[Arul Dhesiaseelan]

Hi,

I am getting an IllegalArgumentException (An operation with name 
[{http://example.com}getGroups] already exists in this service) when I 
have overloaded methods in my web service.

Is it not supported to have overloaded web service methods in JAX-WS?

I have the following methods:

public Groups getGroups();
public Groups getGroups(String pattern);

Please clarify.

Cheers,
Arul
