3.4. JBoss Seam Support

RichFaces is compatible with JBoss Seam and Facelets when run within JBoss Enterprise Application Server. No additional JARs are required. All you need to do is package the RichFaces library with your application.
For Seam 1.2, your web.xml must be as follows: 
<?xml version="1.0" ?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
                   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                   xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
                   version="2.4">

     <!-- richfaces -->

     <filter>
          <display-name>RichFaces Filter</display-name>
          <filter-name>richfaces</filter-name>
          <filter-class>org.ajax4jsf.Filter</filter-class>
     </filter>

     <filter-mapping>
          <filter-name>richfaces</filter-name>
          <url-pattern>*.seam</url-pattern>
     </filter-mapping>

Seam 2.x supports RichFaces Filter, so your web.xml must look like this: 
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
                   xmlns="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_2_5.xsd">

     <context-param>
          <param-name>org.ajax4jsf.VIEW_HANDLERS</param-name>
          <param-value>com.sun.facelets.FaceletViewHandler</param-value>
     </context-param>
