Confusion about gateway

[Jack Beauregard]

Hello all

I made a fine, simple Spring WS to upload a file. All works fine at localhost and with client and service on separate hosts.
Now I'll try to place a gateway between client and service host and I get a 502:

<org.springframework.ws.client.WebServiceTransport Exception: Bad Gateway [502]

Do I need in my client and service code any lines about gateway functionalitiy? e.g. WebServiceGatewaySupport?
