lib下面需要的struts2的jar包
 
源代码目录src下配置struts.xml文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC  
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"  
    "http://struts.apache.org/dtds/struts-2.0.dtd">  
<struts>  
    <package name="struts2" namespace='/' extends="struts-default">  
        
        <action name="p_action" class="srvaction.SrvAction" >  
            <result name="sucess">index.jsp</result>  
            <result name="error">index.jsp</result> 
        </action>                   
    </package>   
</struts>     
 
相关java包和类的代码
package srvaction;
 
 
import hbnado.AdoStudent;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
 
 
 
public class SrvAction extends ActionSupport {
 
private static final long serialVersionUID = 1L;
private String username;
   private String password; 
   
   
   public String getUsername() {
        return username;
   }
 
    public void setUsername(String username) {
         this.username = username;
    }
 
    public String getPassword() {
        return password;
    }
 
    public void setPassword(String password) {
        this.password = password;
    }
 
    
 
public String execute() throws Exception {
try{
     System.out.println("enter username:"+this.getUsername());
 
    
        if (getUsername().equals("xingoo") && getPassword().equals("123")) {
            ActionContext.getContext().getSession().put("user", getUsername());                         
            return SUCCESS;
        }else{
            return ERROR;
        }
}catch(Exception e){
