但有些我无法在jboss上部署它。

Answer 1

您正在使用JSF 2.1实现，但您已将faces-config.xml文件配置为旧JSF 1.2：

<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_1_2.xsd"
    version="1.2">
             ^here's the main problem

只需将faces-config.xml文件更新为正确版本的JSF：

<faces-config xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
    version="2.0">

或者甚至更好，只需删除它并添加仅，如果您要使用任何特定配置（如注册阶段侦听器）。您可以在此处找到此文件的更多用例：What is the use of faces-config.xml in JSF 2?。

除此之外，还有其他主要问题：

JSF 2.x至少需要Servlet 2.5，这是自JBoss 5以来可用的。有关此主题的更多信息，请参阅StackOverflow JSF wiki。
您关注的当前教程是指JSF 1.2，它已经很老了。自2009年以来，JSF 2.0已经发布。我建议您停止学习本教程并转到较新版本，如mkyong's tutorial on JSF 2。

如果您真的想坚持使用JSF 1.2来满足遗留应用程序维护等特定要求，那么将JSF库从2.1替换为1.2。

无法在JBOSS 4.2上部署和运行JSF2.1.6示例
