You ought to use generics to define your AsyncCallback. This probably
isn't causing your problem, but it should look something like this:
serviceClientRemoteAsync.getNom(text, new AsyncCallback<String>() {
public void onFailure(Throwable throwable) {
// display error
}
public void onSuccess(String result) {
// use string
}
});
Your ServiceClientRemote should also declare that it returns a String.
Also, you haven't said what "doesn't work" means. Do you know if the
code in yellow getting run?
