JSF 跳轉至新頁面問題

在Neatbeans中建立JSF檔案,在頁面中放置一個按鈕,作用是點擊此按鈕,跳轉到新的頁面而不顯示新視窗.
做法是:
雙擊JSF頁面中的按鈕,產生JAVA檔案中的ACTION()方法.在方法裡添加如下代碼即可.

  public String button1_action() {
        // TODO: Process the action. Return value is a navigation
        // case name where null will return to the same page.
            if (name.getText().equals("Kage")) {
            try {
                this.getFacesContext().getExternalContext().redirect(
                        "/Action-war/faces/Page2.jsp");
            } catch (Exception e) {
                e.printStackTrace();
            }
        } else {
            name.setText("Name is wrong!");
        }

        return null;
    }
