Facelets + JSF2.0 + EL2 on JBoss 4.0.3 Tomcat 5.5

So I had this painful task to bring JSF2 to life on a very old platform. My customer is using Tomcat 5.5 / JBoss 4.0.3 SP1. After many days of try and fail I managed to gather a configuration that works. The following are the jars that work on this configuration (I am using XHTML. JSP2 do not work as far as I know but I haven't realy tried): commons-beanutils-1.8.3.jar commons-codec-1.3.jar commons-collections-3.2.jar commons-digester-1.8.jar commons-discovery-0.4.jar commons-logging-1.1.1.jar el-api.jar jboss-el-2.0.0.GA.jar jstl-1.2.jar myfaces-bundle-2.0.18-20130417.135111-27.jar ojdbc14.jar standard.jar Please not that I have removed the JBoss original JSF-LIBs and the referencees to this folder. Also, there is some necessary configuration to be performed: Remove FaceletViewHandler from faces-config.xml (basicaly you can leave it empty): com.sun.facelets.FaceletViewHandler And here is the whole web.xml: org.apache.myfaces.EXPRESSION_FACTORY org.jboss.el.ExpressionFactoryImpl javax.faces.PROJECT_STAGE Development javax.faces.DEFAULT_SUFFIX .xhtml facelets.REFRESH_PERIOD 2 facelets.DEVELOPMENT true Faces Servlet javax.faces.webapp.FacesServlet 1 Faces Servlet *.faces index.jsp index.html Cheers,
