我用JSF2.0写了一个动态web项目，可以在Glassfish 3.0.1中成功部署。现在我想把它移到Tomcat 7。但是我在部署过程中遇到了以下异常：

javax.servlet.ServletException: WELD-001303 No active contexts for scope type javax.enterprise.context.RequestScoped
javax.faces.webapp.FacesServlet.service(FacesServlet.java:325)

根本原因

我不明白为什么会这样。我没有在我的代码中使用任何RequestScoped 。这是我的 Tomcat 的 lib jar：

    annotations-api.jar
    catalina-ant.jar
    catalina-ha.jar
    catalina-tribes.jar
    catalina.jar
    ecj-3.6.2.jar
    ecj-4.2.2.jar
    el-api-2.2.jar
    el-impl-2.2.jar
    jasper-el.jar
    jasper.jar
    jsf-api-2.0.jar
    jsf-impl-2.0.6.jar
    jsp-api.jar
    jstl-1.1.2.jar
    ojdbc14.jar
    servlet-api.jar
    standard.jar
    tomcat-api.jar
    tomcat-coyote.jar
    tomcat-dbcp.jar
    tomcat-i18n-es.jar
    tomcat-i18n-fr.jar
    tomcat-i18n-ja.jar
    tomcat-jdbc.jar
    tomcat-util.jar
    weld-servlet-1.0.1-Final.jar

而我的 JSF 项目的 web.xml 是这样的：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">

  </servlet>
  <servlet-mapping>

    <url-pattern>*.jsf</url-pattern>
  </servlet-mapping>
  <context-param>
    <param-name>primefaces.THEME</param-name>
    <param-value>casablanca</param-value>
  </context-param>
  <listener>
    <listener-class>org.jboss.weld.environment.servlet.Listener</listener-class>   
  </listener>
</web-app>

有人可以帮我吗？我被这个问题困扰了好几天。非常感谢！
