I'm trying to use in my JSF 2.1.29_01 project the RichFaces 4.5.2.Final, but it's not exasctly working. I added the following skin parameters to my web.xml:

<context-param>
    <param-name>org.richfaces.skin</param-name>
    <param-value>emeraldTown</param-value>
</context-param>

    <!-- JSF mapping -->
<servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<!-- Map these files with JSF -->
<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>

<!-- Making the RichFaces skin spread to standard HTML controls -->

<context-param>
    <param-name>org.richfaces.enableControlSkinning</param-name>
    <param-value>true</param-value>
</context-param>

And it doesn't work. What exactly doesn't work is the RichFaces resources couldn't be found. They were plugged in the final HTML output as follow:

<link type="text/css" rel="stylesheet" href="/JavaServerFaces
/org.richfaces.resources/javax.faces.resource/org.richfaces
/skinning.ecss?db=eAFL29S2EQAFbwJQ">

but in fact, they were not applied and when I try to reach the resources (type 

localhost:8080/JavaServerFaces 
    /org.richfaces.resources/javax.faces.resource/org.richfaces
    /skinning.ecss?db=eAFL29S2EQAFbwJQtype

via a browser I get 404. After that I tried to add ResourceServlet into my web.xml as follows:

<servlet>
    <servlet-name>Resource Servlet</servlet-name>
    <servlet-class>org.richfaces.webapp.ResourceServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
    <servlet-name>Resource Servlet</servlet-name>
    <url-pattern>/org.richfaces.resources/*</url-pattern>
</servlet-mapping>

Now when I try to reach the resource I get the following exception:

javax.el.ELException: Error Parsing: "#{a4jSkin.imageUrl('buttonBackgroundImage.png')}"
    com.sun.el.lang.ExpressionBuilder.createNodeInternal(ExpressionBuilder.java:124)

How can I fix that?

#{a4jSkin.imageUrl('buttonBackgroundImage.png')}

This EL syntax whereby a bean method is invoked with an argument wasn't supported before EL 2.2. This in turn suggestes that you're deploying to a Servlet 2.5 / EL 2.1 container or older.

Based on your previous questions, I gather that upgrading to at least Servlet 3.0 is not possible. In that case, you'd better supply a custom EL 2.1 implementation along the webapp which supports the given EL 2.2 syntax, such as JBoss EL.
