Newbie Spring Service into Action Injection problem

[springnewbie1234]

I'm getting a null pointer from my service I have injected into my action--everything seems to be wired? Stuck.. can anyone PLEASE help?? Thanks in advance!!!

service.xml:
<beans>
<bean id="userService" class="service.user.UserServiceImpl"/>
</beans>

service interface class:
public interface UserService {
public UserDTO getUser();
}

serviceImpl class:
public class UserServiceImpl implements UserService {
public UserDTO getUser() {
// TODO Auto-generated method stub
UserDTO userDTO= new UserDTO();
userDTO.setUserId("jdoe");
userDTO.setUserName("John Doe");
return userDTO;
}
}

action.xml
<bean name="/loginAction" class="action.login.LoginAction">
<property name="userService">
<ref bean="userService"/>
</property>
</bean>
<bean id="userService" class="service.user.UserServiceImpl"/>

Action Class

public class LoginAction extends BaseAction {
private static final Log log = LogFactory.getLog(LoginAction.class);

private UserService userService;

public UserService getUserService() {
return userService;
}

public void setUserService(UserService userService) {
this.userService = userService;
}


public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {

UserDTO userDTO = getUserService().getUser(); // THROWS NPE
return (mapping.findForward("login"));
}

I see one problem here:

public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException {

UserDTO userDTO = getUserService().getUser(); // THROWS NPE
return (mapping.findForward("login"));
}

, if you do it like so, you simply are calling 'login forward' without any parameters passed through request, so you have to do something like this:

request.setatribute("user",userDTO.getUser() );

That won't help..

The problem was in my struts-config.xml. The type had to be changed to the DelegatingActionProxy.

<action path="/Login" type="org.springframework.web.struts.DelegatingAct ionProxy">
<forward name="login" path="tile.tile" />
</action>
