Methods defined in the Async interface should not throw exceptions
(otherwise you have to surround them by a try catch bloc when using it
in your client code) and must have void return types :
public void getName(int id,AyncCallback);
instead of
public String getName(int id,AyncCallback) throws ClientException;
I did not encounter any problem while retrieving exception messages in
onFailure method.
How do you use your service ?
