JSF beginner error: Cannot find FacesContext

[Leticia Barbalho]

Hello guys,

I am finding the error "Cannot find FacesContext" while running my JSF webapp. I googled it and found that in most cases the error is regarding web.xml, right? Well I'm posting this because I think that is not my problem.

I start to prepare an application.. and I fix its web.xml and faces-config.xml. I add the necessary libs. Then, I write an index.jsp with only HTML contento on it. It runs ok.
But then if I change this jsp to one that has calls to JSF tags and it gives me the Cannot Find FacesContext error.

Will anyone help? Below go my files:

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee [url=http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">]http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">[/url]

    </context-param>
    <context-param>

        <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
        </servlet>
    <servlet-mapping>
        <servlet-name>Faces Servlet</servlet-name>
        <url-pattern>/faces/*</url-pattern>
    </servlet-mapping>
    <session-config><session-timeout>
            30
        </session-timeout></session-config><welcome-file-list><welcome-file>
            index.jsp
        </welcome-file></welcome-file-list></web-app>

faces-config.xml:

<?xml version='1.0' encoding='UTF-8'?>
 
 
<!DOCTYPE faces-config PUBLIC
  "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN"
  "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">
 
<!-- =========== FULL CONFIGURATION FILE ================================== -->
<faces-config>
      
</faces-config>
 

The simple fact of putting a "<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>" line in the index.jsp causes the error.
Is it the right line to include? Is the http address correct?

Oh. And I have the following libraries added:
- commons-beanutils.jar
- commons-collections.jar
- commons-digester.jar
- commons-logging.jar
- jsf-api.jar
- jsf-impl.jar
- jstl.jar

Is there something wrong? hehehe
thanks

Can you show the JSP file and also the URL you are using to access the page?

Thanks.

[Alexander Jesse]

what URL are you using to call this index.jsp?

If it is "..../index.jsp", then the JSF-lifecycle is not entered, and all JSF-tags cough up.
If it is "..../index.jsf" then the lifecycle is not entered because the web.xml has the not corresponding mapping...

If it is "..../faces/index.jsp" then the lifecycle is entered and therefor the message should not be shown.
