Neither BindingResult nor plain target object for bean name 'newUser' available as request attribute

I’m new in Spring and trying to make a RegisterController for my Web portal. When I push button “Register” on my main page it shows this error:"Neither BindingResult nor plain target object for bean name 'newUser' available as request ". I’ve already read a lot of posts on this topic but any of them were helpful.

RegisterController.class

import com.springapp.Entity.User;
import com.springapp.Service.UserService.UserService;
import com.springapp.mvc.RegisterForm;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.ui.ModelMap;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import javax.servlet.http.HttpServletRequest;
import javax.validation.Valid;

@Controller
@RequestMapping(value = "/register.do")
public class RegisterController {
//Log4j
private static final Logger logger = Logger.getLogger(RegisterController.class);

@Qualifier("userServiceImpl")
@Autowired
private UserService userService;

private void putNewUserForm(ModelMap model) {
    RegisterForm newUser = new RegisterForm();
    model.addAttribute("newUser", newUser);
}

@RequestMapping(method = RequestMethod.GET)
public String register(ModelMap model) {
    putNewUserForm(model);
    return "register";
}

@RequestMapping(method = RequestMethod.POST)
public String processRegister(@ModelAttribute("newUser") 
       @Valid final RegisterForm  newUser, final BindingResult result, 
       Model model, HttpServletRequest request) {
    if (result.hasErrors()) {
        logger.debug("result has errors!");
        return "register";
    }
    if (createUser(newUser, model)) {
        return "register";
    }
    return "welcome";
}

private boolean createUser(RegisterForm newUser, Model model) {
    User user = newUser.getUser();
    userService.insertUser(user);
    return false;
 }
}

Register.jsp

I tried to set commandName="newUser", but no difference.

<DIV class="registration_block">

           <sf:form method="POST" modelAttribute="newUser" action="${app}/register.do">

                <sf:label path="login"><strong>Enter Login:</strong></sf:label>
                <span class="error"><form:errors path="login"/></span>
                <br>

                .........

                <input type="SUBMIT" name="SUBMIT" value="Register"/>
            </sf:form>
