на4ал изу4ать JSF и при выполнении первого примера возникли проблемя!
есть следующии код:

UserNumberBean.java

Код


public class UserNumberBean {
    Integer randomInt = null;
    Integer userNumber = null;
    String response = null;
    private boolean maximumSet = false;
    private boolean minimumSet = false;
    private long maximum = 0;
    private long minimum = 0;

    public UserNumberBean() {
        Random randomGR = new Random();
        randomInt = new Integer(randomGR.nextInt(10));
        System.out.println("Duke's number: " + randomInt);
    }

    public void setUserNumber(Integer user_number) {
        userNumber = user_number;
    }

    public Integer getUserNumber() {
        return userNumber;
    }

    public String getResponse() {
        if ((userNumber != null) && (userNumber.compareTo(randomInt) == 0)) {
            return "Yay! You got it!";
        } else {
            return "Sorry, " + userNumber + " is incorrect.";
        }
    }

    public long getMaximum() {
        return (this.maximum);
    }

    public void setMaximum(long maximum) {
        this.maximum = maximum;
        this.maximumSet = true;
    }

greeting.jsp стр. 13 попробуй без этого

Автор: ratzko 3.2.2008, 00:13

ne pomoglo vse ravno toze samoe!

Автор: v2v 3.2.2008, 00:50

в данном примере проблемы с локализацией приложений.
это никак не связано с jsf.
попробуй http://www.coreservlets.com/JSF-Tutorial/туториал

Добавлено через 21 секунду
там всё пошагам хорошо разъяснено.

Автор: ratzko 3.2.2008, 12:51

v2v, спасибо!
попробую...

Автор: ratzko 3.2.2008, 14:06

v2v, попробовал тот туториал, только заменил либы на те 4то использовал и в предыдущем примере тоже самая ощибка!

Автор: Kangaroo 3.2.2008, 14:12

ratzko,
а откуда первый пример? Я просто тоже недавно делал этот пример, с угадыванием чисел для Duke и все работало ок...
дай ссылку, мы почитаем, может что-то найдем..

Kangaroo, не осталось того примера в готовом виде? если есть скинь на по4ту!? [email protected]

Автор: Kangaroo 3.2.2008, 18:42

ratzko,
а чем вы запускали? Только что попробовал вот так:

Цитата

To build, package, deploy, and run this example using NetBeans IDE, follow these steps:

   1. In NetBeans IDE, select File→Open Project.
   2. In the Open Project dialog, navigate to:
        tut-install/javaeetutorial5/examples/web/

   3. Select the guessNumber folder.
   4. Select the Open as Main Project check box.
   5. Click Open Project Folder.
   6. In the Projects tab, right-click the guessNumber project, and select Deploy Project.
   7. To run the application, open the URL http://localhost:8080/guessNumber in a browser.

Все работает.
