Error deploying jsf application in JBoss 5.1 - jsf

Question

I have a big problem when I deploy my application in jboss 5.1. When it starts, I get this:
org.jboss.web.jsf.integration.config.JBossJSFConfigureListener
com.sun.faces.config.ConfigurationException: It appears the JSP version of the container is older than 2.1 and unable to locate the EL RI expression factory, com.sun.el.ExpressionFactoryImpl. If not using JSP or the EL RI, make sure the context initialization parameter, com.sun.faces.expressionFactory, is properly set.
I read many things about this bug, and nothing works for me.
I haven't jsf-api and jsf-impl in my WEB-INF/lib.
Here is my web.xml:

I don't understand what is the problem.
Thanks for your help.

I have found the solution.
Jboss 5.1 come with JSF 1.2.12 and this version seem to not work with jboss el.
So I have added this in my web.xml:
<context-param>
<param-name>org.jboss.jbossfaces.WAR_BUNDLES_JSF_IMPL</param-name>
<param-value>true</param-value>
</context-param>
And in my pom.xml, I fixe a newer version (1.2.13 for exemple) for jsf-api and jsf-impl and I remove the scope provided.
The war is deploy with this own jsf version and all work fine.
