Hi All,
I cannot understand why I get an error from Tomcat, when
trying to forwarding from an initial JSP with JSF to another one when
the application starts and I noticed the same problem during the
homework examples.
I'm on the very 1st excercise of the course about JSF (#4104).
My application starts with welcomeJSF.jsp below:
---------------------------------------------------------------------------
<%...@page contentType="text/html"%>
<%...@page pageEncoding="UTF-8"%>
<%...@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%...@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd";>
<%--
This file is an entry point for JavaServer Faces application.
--%>
<f:view>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html;
charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<h1><h:outputText value="JavaServer Faces" /></h1>
<jsp:forward page="/faces/Address.jsp" />
</body>
</html>
</f:view>
---------------------------------------------------------------------------
This file calls /faces/Address.jsp, which is reported below:
---------------------------------------------------------------------------
<%...@page contentType="text/html" pageEncoding="UTF-8"%>
<%...@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%...@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>

</head>
<body>
<h1>Address.jsp</h1>
<h:outputText value="h:outputText tag" />
</body>
</html>
</f:view>
---------------------------------------------------------------------------
I receive the following error:

All works with plain JSP files, but when adding JSF tags, this problem
occurs.
Could you please help?
Thanks a lot!!
