JSF 2 with Tomcat 6

Question

Has anyone tried running JSF2 on Tomcat 6? I tried to do this but running into EL compatibility issues. Tried various combinations but nothing worked. I did the setup and test based on the following post.
http://weblogs.java.net/blog/cayhorstmann/archive/2009/12/29/jsf-20-and-tomcat
If anyone accomplished this, please post the following
1) list of libraries in tomcat lib
2) list of libraries in WEB-INF/lib
3) web.xml configuration
I have the following config and my sample page only displays plain HTML but not any JSF text box fields.
I added the following to tomcat lib
el-api-2.2.jar
el-impl-2.2.jar
jstl-api-1.2.jar
jstl-impl-1.2.jar
I have the following in WEB-INF/lib
jsf-api.jar
jsf-impl.jar
jstl-api-1.2.jar
jstl-impl-1.2.jar
weld-servlet.jar
My web.xml is:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xmlns="http://java.sun.com/xml/ns/javaee"

     <url-pattern>*.faces</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.xhtml</welcome-file>
</welcome-file-list>
</web-app>
I also have an empty beans.xml in my WEB-INF folder. This is required for Weld.
Anyone, plese help.

Has anyone tried running JSF2 on Tomcat 6? Yep, I use the Mojarra JSF 2 implementation in Tomcat 6 all the time, and many of my students and clients have as well.
I have used various different Mojarra 2.0.x releases without problems on Tomcat 6, Tomcat 7, Glassfish 3, and JBoss 6
(minus the JAR files in the Java EE 6 containers). JSF 2 is supposed to run in any container that supports servlets 2.5 and later,
and I have gotten reports of it running on the Google Cloud Server, which I think is running Jetty.
Maybe you could be more specific about the constructs that caused problems and the error messages that you got?
Here are some details:
1) Here is my web.xml. The PROJECT_STAGE and welcome-file-list entries are optional. Your sample app had some
extra things in the web.xml that were not related to JSF; I would suggest removing them first to test a barebones
JSF 2 app before trying to combine technologies.
<?xml version="1.0" encoding="UTF-8"?>
<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/web-app_2_5.xsd"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
      http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
  version="2.5">
  <servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.jsf</url-pattern>
  </servlet-mapping>
  <context-param>
    <param-name>javax.faces.PROJECT_STAGE</param-name>
    <param-value>Development</param-value>
  </context-param>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>
</web-app>2) The JAR files I have in WEB-INF/lib are jsf-api.jar, jsf-impl.jar, jstl-api-1.2.jar, and jstl-impl-1.2.jar.
The JSTL JAR files are actually not needed for the simple apps I link to below, but are needed for
any JSF 2.0 app that uses ui:repeat, so IMHO should be considered a required part of a JSF 2.0 app.
3) Here is my faces-config.xml file (the trivial apps below don't use any declarations in it,
so it just has start and end tags):
<?xml version="1.0"?>
<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">
</faces-config>4) Of course, it is not used by the server at all, but I also think it is a good practice to add the JSF 2.0
project facet if you are using Eclipse 3.6. That way, you get some help from the IDE when editing faces-config.xml and any .xhtml file.
5) Here are two very simple Eclipse projects that you can download and try. They follow the structure outlined above, and they work
for me in Tomcat 6, Tomcat 7, and Glassfish 3 as is. They will run in JBoss 6 if you remove the JAR files from WEB-INF/lib (and, removing
the JAR files is really the right thing to do in Glassfish also, although they do in fact run as is).
