5.修改配置文件l
<!-- 配置托管Bean -->
<managed-bean>
<managed-bean-name>dw</managed-bean-name>
<managed-bean-class>com.dw.action.MyJsfAction</managed-bean-class >
<managed-bean-scope>session</managed-bean-scope> </managed-bean>
<!-- 定义导航规则与页面-->
<navigation-rule>
<from-view-id>/userChoose.jsp</from-view-id>
<navigation-case>
<from-outcome>JAVA</from-outcome>
<to-view-id>/newJava.jsp</to-view-id>
</navigation-case>
<navigation-case>
<from-outcome>C</from-outcome>
<to-view-id>/newC.jsp</to-view-id>
</navigation-case>
</navigation-rule>
<listener-class>faces.webapp.StartupServletContextLi stener</listener-class>
</listener>
<!-- 配置JSF的配置文件-->
<context-param>
<param-name>javax.faces.CONFIG_FILES</param-name>
<param-value>/l</param-value> </context-param>
<!-- 处理请求的servlet -->
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>0</load-on-startup>
</servlet>
<!-- 配置所有.jsf结尾的请求都由JSF处理-->
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
7.Run on server，浏览器访问localhost:8080/FirstJSFTestProject/userChoose.jsf（否则，
会报错!）
备注：
1.需要注意将jsp文件放置在webcontent目录下，否则不到。
2.需要导入jstl的jar包，否则，会报错java.lang.NoClassDefFoundError:
javax/servlet/jsp/jstl/core/Config。
3.项目代码结构：
4.Jar下载链接：/dist/jakarta/taglibs/standard/binaries/
