}
else

}
}
public void adduser(Userlist user)
{
String phone= user.getTel();
service.insert(phone);
}
}
the question is that when i first time input a phone number ,login successful,and get the right username . and when i surf the page again ,submit with another phonenumber its ok .but the third time with another phone number login the user name is name before. i check the eclipse console find the third time request didnt send to the action,because the several "System.out.println()" didnt printed. the get name page is a page with ajax to get another action to return the "user" attribute of session.
