calling a new method in java from mxml produces "cannot invoke method" error

UserService.java

...
        public class UserService {
                public static User getUser(String username, String password) {
                        ...
            开发者_开发百科    }   

                public static User getUser2(String username, String password) {
                        ...
                }   
        }  

login.mxml

    private function loginUser() : void {
            lostPassword = false;

            // this works fine
        UserService.getUser(username.text, password.text);

            // this fails !
        UserService.getUser2(username.text, password.text);

        }

getUser was already in UserService.java. I just created getUser2 and it's identical to getUser. When I try to call getUser2, i get the "Cannot invoke method" error.

question: Do I need to specify getUser2 in some other file? like in some configuration file? if so, which one and how do I do it.

Thanks.

think problem is JAVA static method according to Remoting Service definition

The Remoting Service lets a client application access the methods of server-side Java objects

In java/oops static methods are not associated to Object/instance its depends-upon/associated to class

your method should be like this to accept call from flex

public class UserService {
                public User getUser(String username, String password) {
                        ...
                }   

                public User getUser2(String username, String password) {
                        ...
                }   
        }  

Hopes that helps
