what doing wrong!
you binding form list of users instead of user object.
change controller method this
public modelandview getuserlist(modelmap model){ list<user> userlist = userservice.getuserlist(); modelandview model = new modelandview("userlist"); model.addattribute("userlist", userlist); model.addattribute("user", new user()); return model; }
