Answer 1

}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
有啊

Answer 2

Cannot find bean: "loginbean" in any scope 
你创建的formbean丢失了，或者没有创建。仔细检查一下，要看struts的源码呀，我项目遇到
过一次，至今都不知道原因。

Answer 3

<bean:write name="loginbean" property="username"> </bean:write>利用<bean:write>输出的对象必须存放在四种属性范围之中．
不然的话，它根本找不到loginbean这个属性．
只是我的看法，你可以试试．．．

Answer 4

while(rs.next()) 
{ 
String uuserid=rs.getString("userid"); 
String username=rs.getString("username"); 
String password=rs.getString("password"); 
    
                request.setAttribute("userid",uuserid); 
                request.setAttribute("username",username); 
                request.setAttribute("password",password); 
                System.out.println(username); 
                
                LoginBean loginbean=new LoginBean(); 
                loginbean.getUserid(); 
                loginbean.getUsername(); 
                loginbean.getPassword(); 
                System.out.println(username); 
                  request.setAttribute("loginbean",loginbean); 
                
} 
上面的LoginBean刚new 出来，怎么就开始get属性了~~~应该是set吧~~~其它的代码我没看~~我觉得这要改为：
LoginBean loginbean=new LoginBean(); 
                loginbean.setUserid(userid); 
                loginbean.setUsername(username); 
                loginbean.setPassword(password); 
                System.out.println(username); 
                  request.setAttribute("loginbean",loginbean);

Answer 5

while(rs.next())
{
String uuserid=rs.getString("userid");
String username=rs.getString("username");
String password=rs.getString("password");
    LoginBean loginbean = new LoginBean();
    //封装属性
                loginbean.setUserid(uuserid);
                loginbean.setUsername(username);
                loginbean.setPassword(password);
                System.out.println("loginbean:"+username);
           //把查出来的值放在request里    
           request.setAttribute("loginbean",loginbean); 在jsp中 ${requestScope.loginbena.username}
