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.

Was it helpful?

Solution

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

OTHER TIPS

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.
