Tôi chỉ mới bắt đầu với JSF 2.0 và tôi gặp vấn đề ngay từ đầu. Thẻ JSF không được phân tích cú pháp.Thẻ JSF không hiển thị - FacesServlet không hoạt động?
Dưới đây là một số chi tiết. Hy vọng ai đó có thể giúp đỡ vì không có câu hỏi nào liên quan đến SO có thể giải quyết được vấn đề của tôi.
hello.jsp

<h:body>
<f:view>
asd
<h:inputText value="asd" label="UserName"></h:inputText>

</html>
gì tôi thấy khi điều hướng đến http://localhost:8080/JSFDeneme/pages/hello.jsp
Chỉ rõ asd
Xem nguồn http://localhost:8080/JSFDeneme/pages/hello.jsp
chính xác giống như các nội dung của hello.jsp

<description>
This parameter tells MyFaces if javascript code should be allowed in
the rendered HTML output.
If javascript is allowed, command_link anchors will have javascript code
that submits the corresponding form.
If javascript is not allowed, the state saving info and nested parameters
will be added as url parameters.
Default is 'true'</description>

<description>
If true, rendered HTML code will be formatted, so that it is 'human-readable'
i.e. additional line separators and whitespace will be written, that do not
influence the HTML code.

If true, a javascript function will be rendered that is able to restore the
former vertical scroll on every request. Convenient feature if you have pages
with long lists and you do not want the browser page to always jump to the top
if you trigger a link or button action that stays on the same page.
Default is 'false'

Những gì tôi đã ở WEB-INF/lib
- JSF 2.0 (Apache MyFaces JSF Core-2.0 API 2.0.2) - Eclipse tải về mà
- JSTL-api-1.2.jar
- JSTL-impl-1.2. jar
- primefaces-3.0 lọ
gì Tomcat in để an ủi khi tôi khởi động lại máy chủ và điều hướng đến trang
01.235.Có vẻ như không có gì lạ và không đề cập đến FacesServlet

Mọi trợ giúp đều được đánh giá cao.
tôi đổi tên thành 'hello.jsp' cho 'hello.xhtml' nhưng sau đó khi tôi hướng đến' http:// localhost: 8080/JSFDeneme/pages/hello.xhtml', tôi nhận được thông báo 'Rất tiếc! Liên kết này dường như bị hỏng.' trang? Tôi nên điều hướng đến đâu để xem trang? –
Nếu bạn đã thay thế mẫu URL, bạn cần xóa '/ trang' khỏi URL. Xem thêm URL ví dụ trong câu trả lời của tôi. – BalusC
Hoạt động như một sự quyến rũ của BalusC! Cảm ơn rất nhiều. Còn 2 câu hỏi nữa, bạn sẽ đề xuất 'DOCTYPE' nào? Hoặc bạn thậm chí sẽ đề nghị sử dụng một? Và thứ hai, tôi có phải sử dụng phần mở rộng '.xhtml' không? Tôi có thể sử dụng thứ gì đó khác như '.do' hay gì đó tùy ý không? Bởi vì khi phần mở rộng tập tin là '.xhtml' và tôi thêm một' url-mapping' khác, chẳng hạn như '.jsf', nó không hoạt động. –
