WSDL2Java generates 2 client/server files?

[Guy Pardon]

Hi,

After running wsdl2java I get these generated (wsdl-specific) client  
and server classes:

CoordinatorPortTypeClient.java and also
CoordinatorPortTypeClient_Client.java

Same for the server:
CoordinatorPortTypeServer.java and also
CoordinatorPortTypeServer_Server.java

The content is identical for each pair. It seems like this is  
generated twice.

Could this be due to some double import in the WSDL or so?

Thanks
Guy
