If you use gwt-rpc, make a default asyncallback like this:
public abstract class DefaultAsyncCallback<T> implements
com.google.gwt.user.client.rpc.AsyncCallback<T> {
private static final char flag = '0';
@Override
public void onFailure(Throwable e) {
if (isUnAuthenticatedUser(e)) showLogin();
}
}
And use everywhere.
