刚开始在学习jsf,按照网上的一篇电子文档写的做：
web.xml配置：
- XML code
<?xml version="1.0" encoding="ISO-8859-1"?><web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2eehttp://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4"> <description>JSF Demo</description> <display-name>JSF Demo</display-name> <servlet> <servlet-name>Faces Servlet</servlet-name> <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-list></web-app>
UserBean:
- Java code
public class UserBean { private String name; private String password; private String errMessage; public void setName(String name) { this.name = name; } public String getName() { return name; } public void setPassword(String password) { this.password = password; } public String getPassword() { return password; } public void setErrMessage(String errMessage) { this.errMessage = errMessage; } public String getErrMessage() { return errMessage; } public String verify() { if (!name.equals("golden") || !password.equals("123456")) { errMessage = "名称或密码错误"; return "failure"; } else { return "success"; } }}faces-config.xml
- XML code
<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE faces-config PUBLIC"-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.0//EN""http://java.sun.com/dtd/web-facesconfig_1_0.dtd"><faces-config> <navigation-rule> <from-view-id>/pages/index.jsp</from-view-id> <navigation-case> <from-outcome>success</from-outcome> <to-view-id>/pages/welcome.jsp</to-view-id> </navigation-case> <navigation-case> <from-outcome>failure</from-outcome> <to-view-id>/pages/index.jsp</to-view-id> </navigation-case> </navigation-rule> <managed-bean> <managed-bean-name>user</managed-bean-name> <managed-bean-class> onlyfun.caterpillar.UserBean </managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean></faces-config>
