一旦我尝试通过"http://localhost:8080/beginner/faces/index.jsf"打开我的index.xhtml,我将得到以下异常:
javax.servlet.ServletException
javax.faces.webapp.FacesServlet.service(FacesServlet.java:606)
org.jboss.weld.servlet.ConversationPropagationFilter.doFilter(ConversationPropagationFilter.java:62)
java.lang.NullPointerException

在eclipse中,我通过"新Maven项目向导"创建了一个Maven项目并选择了Group Id:"org.jboss.spec.archetypes",Artifact Id"jboss-javaee6-webapp-blank-archetype"version:7.13我正在使用JBoss 7.1.1.FINAL并尝试了JDK 6和JDK7
index.xthml看起来像这样:
<?xml version="1.0" encoding= "UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html">
<h:head>
<title>First JSF</title>
</h:head>
<h:body>
<h1>Hello there</h1>
</h:body>

我找了几个小时是有原因的,但是找不到任何解决方案,尽管我做了这个研讨会书告诉我要做的每一步.
