I tried running the same address.war that comes with the ICEfaces-1.6.0-DR4 and get the below exception when running in the container, java.lang.NullPointerException at javax.faces.webapp.FacesServlet.init(FacesServlet.java:165) at com.caucho.server.dispatch.ServletConfigImpl.createServlet(ServletConfigImpl.java:600) at com.caucho.server.dispatch.ServletManager.init(ServletManager.java:152) at com.caucho.server.webapp.Application.start(Application.java:1599) I would think all the jars should be in the sample war, does anybody know what jar is missing that would cause this null pointer exception
