private UserService usrService;
private UserServiceImp userService;
private String message;
private String username;
private String password;
private ResourceBundleMessageSource messageSource;
public LoginAction() {
}
@Override
public String execute() throws Exception {
User usr= userService.getUser(username);
if(usr != null){
if(usr.getPassword().equals(password)){
message = messageSource.getMessage("loginSuccess",
null,Locale.UK);
}else{
message = messageSource.getMessage("pswError",
null,Locale.UK);
}
}else{
message = messageSource.getMessage("usrError",
null,Locale.CHINA);
}
return SUCCESS;
}
public String getMessage() {
return message;

this.message = message;
}

public void setUsername(String username) {
this.username = username;
}
public String getPassword() {

}
public void setPassword(String password) {
this.password = password;
}
public UserServiceImp getUserService() {

You were on the right track before, you just want the following in your
class -
->snippet
private UserService userService;
public void setUserService(UserService userService) {
this.userService = userService;
}
<- end snippet
I am curious if it's 'userService' that is null... This would mean
that your action isn't being wired with the service from Spring. I
snipped all the previous messages from this email, so i can't look
through it for you, but I will say that this sort of thing is
generally a simple property misspelling or some other detail (decimal
point? I always mess up some mundane detail). If it's username that is
null, you might want to check that your form is properly setup in your
JSP.
