JSF在JBoss4.2.2 GA上部署出现java.lang.ClassCastException

imA 2007-12-14 08:31:03

我写了一个简单的JSF应用，代码如下：
web.xml

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">

    <servlet-class>

    javax.faces.webapp.FacesServlet</servlet-class>

    <load-on-startup>1</load-on-startup>

  </servlet>

  <servlet-mapping>

    <servlet-name>Faces Servlet</servlet-name>

    <url-pattern>*.faces</url-pattern>

  </servlet-mapping>

  <welcome-file-list>

    <welcome-file>index.html</welcome-file>

    <welcome-file>index.htm</welcome-file>

    <welcome-file>index.jsp</welcome-file>

    <welcome-file>default.html</welcome-file>

    <welcome-file>default.htm</welcome-file>

    <welcome-file>default.jsp</welcome-file>

  </welcome-file-list>

</web-app>

faces-config.xml

<?xml version="1.0" encoding="UTF-8"?>



<faces-config xmlns="http://java.sun.com/xml/ns/javaee"

	</navigation-rule>



</faces-config>

pages/index.jsp

<%@ taglib uri="/WEB-INF/jsf_core.tld" prefix="f"%>

<%@ taglib uri="/WEB-INF/html_basic.tld" prefix="h"%>

<%@ page contentType="text/html;charset=GB2312"%>

<html>

<head>

<title>第一个JSF程序</title>

</head>

<body>

<f:view>

  <h:form>

    <h3>请输入您的名称</h3>

      名称：<h:inputText value="#{user.name}" />

    <p><h:commandButton value="送出" action="login" />

  </h:form>

</f:view>

</body>

</html>

pages/welcome.jsp

<%@ taglib uri="/WEB-INF/jsf_core.tld" prefix="f"%>

<%@ taglib uri="/WEB-INF/html_basic.tld" prefix="h"%>

<%@ page contentType="text/html;charset=GB2312"%>

<html>

<head>

<title>第一个JSF程序</title>

</head>

<body>

<f:view>

  <h:outputText value="#{user.name}" />您好！

      <h3>欢迎使用JavaServer Faces！</h3>

</f:view>

</body>

</html>

f.jsf.UserBean.java

package f.jsf;

 

public class UserBean {

  private String name;

 

  public String getName() {

    return name;

  }

 

  public void setName(String name) {

    this.name = name;

  }

 

}

目录结构如下图：

我将这个应用打包成war格式，然后部署到%JBoss_Home%\server\default\deploy目录下，然后启动JBoss（run -c default），在启动时产生了如下异常:
2007-12-13 14:30:26,963 ERROR [STDERR] java.lang.ClassCastException: com.sun.faces.lifecycle.LifecycleFactoryImpl

我用的jsf版本是1.1，jdk版本是5.

谁能知道怎么回事？帮我找一下线索，我弄了一天了也不知所以然，谢谢。
