What do you mean "they won't work now" ?

 Do you have errors we can look at so we can diagnose the problem ? Or
some sort of analysis of your own ? Have you inspected the requests
being sent by your GWT client with firebug ? It can tell you if the
request is fine so you can be sure that it's not a GWT problem.

Also, make sure that you understand the limitations introduced by the
Same Origin Policy when trying to communicate with a backend different
than plain GWT RPC's

Cheers,

Salvador
