Jest nowy w temacie GWT. Czy w aplikacjach GWT nie można używać wszystkich bibliotek Javy?
Eclipse po uruchomieniu aplikacji w przeglądarce wypluwa mi:
[ERROR] [test_gwt] - Line 216: No source code is available for type java.io.PrintWriter; did you forget to inherit a required module?
linia 216: PrintWriter plik = new PrintWriter("Globals.csv");
[ERROR] [test_gwt] - Line 213: No source code is available for type java.io.InputStreamReader; did you forget to inherit a required module?
[ERROR] [test_gwt] - Line 213: No source code is available for type java.io.BufferedReader; did you forget to inherit a required module?
[ERROR] [test_gwt] - Line 194: No source code is available for type java.net.HttpURLConnection; did you forget to inherit a required module?
[ERROR] [test_gwt] - Line 193: No source code is available for type java.net.URL; did you forget to inherit a required module?
Wszystkie klasy są zaimportowane. Jeśli to coś pomoże to jest to wersja kliencka.
