Issues while Upgrading Jsf1.0 to Jsf2.0

While upgrading application to Jsf2.0 created in Spring3 and Jsf1.0 (myfaces), i am facing some issues mentioned below.

I have done following steps to upgrade the application.

From IntelliJ IDEA:

* Open project settings/Monitor/Dependencies
*  Removed facelet*jar, el*.jars, myfaces* jars from project 
*  Added jsf2.0.x ri mojarra jars and tomahawk1.1.9.jar  
*  Open project settings/monitor/web settings
*  Under "modules and libs to package": remove el-.jars,facelet-jar and myfaces jars
*  Added jsf2.0.x ri mojarra jars and tomahawk1.1.9.jar  
*  Removed erroneous class usages from our classes Lists.java and RegExValidator.java. In Lists.java, replace import with org.apache.commons.lang.LocaleUtils. In RegExValidator, replace import with "org.apache.myfaces.shared_tomahawk.util.MessageUtils".

Edit Web.xml:

*  facelets.VIEW_MAPPINGS -> javax.faces.FACELETS_VIEW_MAPPINGS
*  facelets.LIBRARIES -> javax.faces.FACELETS_LIBRARIES
* Change Faces Servlet to <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
* Change header to:

  <web-app version="2.5"
      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-app_2_5.xsd">

Edit faces-config.xml:

*  Add header:

          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">

*  Remove line "<view-handler>com.sun.facelets.FaceletViewHandler</view-handler>"

After doing all the steps mentioned above getting the following error:

A literal value was specified for attribute actionListener that is defined as a deferred m开发者_高级运维ethod with a return type of void. JSP.2.3.4 does not permit literal values in this case

Actually Jsf2.0 el expressions #{myBean.property} are not getting resolved thats why its showing the above error.

Can anybody guide me, what is missing, so that i can successfully migrate application to Jsf2.0

Thanks in Advance, Dhillon

A literal value was specified for attribute actionListener that is defined as a deferred method with a return type of void. JSP.2.3.4 does not permit literal values in this case

This EL validation error means that you've somewhere a

<h:commandButton actionListener="somestring" />

instead of

<h:commandButton actionListener="#{someBean.actionListener}" />

or

<h:commandButton action="somestring" />

(instead of h:commandButton you can also read any UICommand component like h:commandLink)

Just locate/lookup the culprit in the code and fix it accordingly.

Upgrade web-app version="3.0" to latest. Previously web-app version is 2.5 at that time I got error, after upgrade to 3.0 issue resolved.
