Question

i am trying to upgrade from jsf 1.2 to jsf 2.2.2 on websphere 8.5.1 and what i did is as follows:

1- put jsf-api-2.2.2.jar and jsf-impl-2.2.2.jar in my lib folder.

2- changed header of web.xml to be as follows:

<web-app 
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    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-app_2_5.xsd"
    id="YourWebappID"
    version="2.5">

3- changed header of faces-config.xml to be as follows:

<faces-config
    xmlns="http://java.sun.com/xml/ns/javaee"
    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_2_0.xsd"
    version="2.0">

4- changed the faces servlet to be as follows:

<servlet>
        <servlet-name>Faces Servlet</servlet-name>
        <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>

    <servlet-mapping>
      <servlet-name>Faces Servlet</servlet-name>
      <url-pattern>*.jsf</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
      <servlet-name>Faces Servlet</servlet-name>
      <url-pattern>*.faces</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
     <servlet-name>Faces Servlet</servlet-name>
     <url-pattern>*.xhtml</url-pattern>
    </servlet-mapping>

5- changed the classloader to be parent last on websphere, and i can see in the logs that mojara was initialized successfully.

6- my xhtml page is :

<!DOCTYPE html>
<html lang="en"
    xmlns:f="http://java.sun.com/jsf/core"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:ui="http://java.sun.com/jsf/facelets">
    <h:head>
        <title></title>
    </h:head>
    <h:body>
        <h3>JSF 2.0 Hello World</h3>
        <h:form>
           <h:inputText id="sname" value="test" />   
        </h:form>             
    </h:body>
</html>

and i am getting the following exception:

please advise about this error, do i have to add javaee jars to my lib folder ? do i have to add jsf listener in web.xml ?

EDIT:

This was solved by removing the jsf-api-2.2.2.jar and jsf-impl-2.2.2.jar

and using javax.faces-2.0.10.jar and jboss-el-2.0.0.GA.jar,but i want to make it work with

jsf-api-2.2.2.jar and jsf-impl-2.2.2.jar, please advise how to solve above exception with latest mojara jars.

JSF 2.2 requires at least Servlet 3.0. Reading the definition of your web.xml i see you're still using Servlet 2.5. Change your first line with

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

And your faces-config definition should be like

<faces-config version="2.2"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-facesconfig_2_2.xsd">

WebSphere Application Server 8.5 using MyFaces JSF Implementation by default. There is article in IBM Documentation how to use different JSF implementations.

Also faced with same error during migration Struts 1 -> JSF 2.2 It was occurred by ViewHandlerImpl of struts-faces (1.3.8). Looks like this lib is incompatible with Servlet 3 (which is required by JSF 2.2)

PS: Was working with JSF 2.0 without any changes.

So I can suggest to check all 3rd part filters etc., which can be involved to request processing.

Note for Author, please, pay attention to your code in:

com.filenet.ae.toolkit.server.servlet.filter.SecurityPluginFilter
...
com.filenet.ae.toolkit.server.servlet.filter.ThreadLocalCleanupFilter

This actually answers a different question. Try finding the right question or just ask your own. – BalusC May 20 '15 at 20:02
Sorry, maybe yes but actually I had the same Exception and almost the same stack trace - so similar issue. And I found where was problem on my side and gave some shot suggestion as one of the variants to what direction to dig. Because solution to downgrade JSF to 2.0 is surface. – Yaro May 21 '15 at 09:03
