I actually managed to connect now, I only have one question left now,
why is the "onFailure" from here
private class AuthenticationHandler<T> implements
AsyncCallback<User>
{
public void onFailure(Throwable ex) {
label.setText("Fail");
System.out.println(ex.getStackTrace
());
}
public void onSuccess(User result) {
try {
label.setText("Success");// +
" Pass:: " + result.getPass
().toString()
}catch(Exception e) {
System.err.println("Fail! = "
+ e.getStackTrace());
}
}
}
never called or used or anything??
