Here are my jsp page:

16:     <div id="content">
17:         <jsp:include page="../header.jsp" />
18:         <h1>Nhập hồ sÆ¡ thĂ­ sinh - Kì tuyển sinh 2015</h1>
19:         <f:view>
20:                 <h:form >
21: 
22:                     <!--content-->

I'm a newbie about JSF, what going wrong here?

  • You are not clear about the exception as to when exactly it is thrown. Try giving a reproducible example with your environment especially the JSF version you happen to use. – Tiny Sep 16 '15 at 04:15
  • In the future, always copypaste the exception message and 1st line of stacktrace (without parentheses/linenumber) into a search engine for possible clues/answers. – BalusC Sep 16 '15 at 09:06
