I try build my own MyFaces applications. I always get one of this errors.
First problem:
2005-09-03 00:23:18,112 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/faces-einfach].[jsp]] Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException

at javax.faces.webapp.UIComponentTag.doStartTag(UIComponentTag.java:254)
at org.apache.myfaces.taglib.core.ViewTag.doStartTag(ViewTag.java:90)
Second problem:
Caused by: javax.faces.el.PropertyNotFoundException: Base is null: helloWorldBacking
at org.apache.myfaces.el.ValueBindingImpl.resolveToBaseAndProperty(ValueBindingImpl.java:523)
