javax.faces.facesexception: java.lang.runtimeexception: cannot find facescontext

jsf components in jsp page complaining facescontext cannot found. 1 responsible creating facesservlet.

here,

<servlet-mapping>     <servlet-name>javax.faces.facesservlet</servlet-name>     <url-pattern>*.faces</url-pattern> </servlet-mapping>

you've declared facesservlet listen on url-pattern of *.faces. so, facesservlet run (and create facescontext) need ensure request url matches http://example.com/context/page.faces , not http://example.com/context/page.jsp.

if rather want use http://example.com/context/page.jsf, need change url-pattern of facesservlet *.jsf.

that said, facesredirectfilter suspicious well. isn't redirecting *.jsp *.jsf or so? if so, need modify filter well. however, if sole intent prevent users accessing *.jsp files directly without involvement of facesservlet, better add following security constraint web.xml:

<security-constraint>     <display-name>restrict direct access jsp files</display-name>     <web-resource-collection>         <web-resource-name>jsp files</web-resource-name>         <url-pattern>*.jsp</url-pattern>     </web-resource-collection>     <auth-constraint /> </security-constraint>

(and remove filter).

unrelated problem, mentioned jsf 1.2, you've declared faces-config.xml jsf 1.1. jsf 1.2 implementation or newer fall jsf 1.1 compatibility. need declare jsf 1.2 well.

<faces-config version="1.2"      xmlns="http://java.sun.com/xml/ns/javaee"     xmlns:xi="http://www.w3.org/2001/xinclude"     xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"      xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd">

(and rid of doctype)
