<jsp:useBean id="login" scope="session" class="mybean.Login" />

<% if(!login.isLogin()) {
out.println("对不起，你没有登录！");
} else {
response.reDirection("logonok.jsp")
} %>

//bean Login内容如下:
package mybean;

public class Login
{
int id=(-1);
public Login() {}
public int getID() { return id; }
public boolean isLogin() { return id!=(-1); }
public boolean login(String name, String pass)
{
// 检查name and pass
if(....)
return true;
return false;
}
}
