Spring: The request sent by the client was syntactically incorrect ()

Hi I received next error during the redirect:

The request sent by the client was syntactically incorrect

URL which browser shows is: localhost:8080/Project/menu/main/home/0 and here my classes with redirects first - "from", second "to":

 /*
 * Get all possible values of menu and generate correct url to pages controllers
 * 
 */

@Controller
@SessionAttributes("menu")
public class MainMenuController {


    @ModelAttribute
    public Menu createMenu() {
        return new Menu();
    }

    @RequestMapping(value = "/menu", method = RequestMethod.GET)
    public String mainMenuResolver(@ModelAttribute Menu menu) {
        menu.setMainMenu("first");
        return "forward:/menu/first";
    }

    @RequestMapping(value = "/menu/{mainMenu}", method = RequestMethod.GET)
    public String subMenuResolver(@PathVariable String mainMenu, @ModelAttribute Menu menu) {
        menu.setMainMenu(mainMenu);
        menu.setSubMenu("home");
        return "forward:/menu/first/home";
    }

    @RequestMapping(value = "/menu/{mainMenu}/{subMenu}", method = RequestMethod.GET)
    public String secMenuResolver(@PathVariable String mainMenu, @PathVariable String subMenu, @ModelAttribute Menu menu) {
        menu.setMainMenu(mainMenu);
        menu.setSubMenu(subMenu);
        menu.setSecMenu("0");

        if (menu.getMainMenu().equals("first")){
            return "redirect:/menu/main/"+menu.getSubMenu()+"/"+menu.getSecMenu();
        }

        if (menu.getMainMenu().equals("second")){
            return "redirect:/menu/religion/"+menu.getSubMenu()+"/"+menu.getSecMenu();
        }

        return "redirect:/menu/main/"+menu.getSubMenu()+"/"+menu.getSecMenu();
    }
}

Second class:

@Controller
@SessionAttributes("menu")
public class FirstPageController {

    @ModelAttribute
    public Menu createMenu() {
        return new Menu();
    }

    @RequestMapping(value = "/menu/main/{subMenu}/{secMenu}", method = RequestMethod.GET)
    public ModelAndView menuResolver(@PathVariable String mainMenu, @PathVariable String subMenu,@PathVariable String secMenu, @ModelAttribute("menu") Menu menu) {
        menu.setMainMenu(mainMenu);
        menu.setSubMenu(subMenu);
        menu.setSecMenu(secMenu);       

        if (menu.getSubMenu().equals("home")){
            String title = "Project - Home Page";
            return new ModelAndView("MainPage", "title", title);
        }

        String title = "Project - Home Page";
        return new ModelAndView("MainPage", "title", title);
    }
}

Solved: I solved it, there excess parameter in the method of the second class.

In my case, it was also a problem of conversion, Spring was expecting an Integer however I was entering a String. Try to check what you have passed as parameters to the controller

In cases like this it is very useful to have org.springframework.web loggin level set to DEBUG in log4j configuration

<logger name="org.springframework.web">
    <level value="DEBUG" />
    ...
</logger>

E.g. when parameter is missing or cannot be converted to the required type there will be an exception details in the log.

As said ike3, using the detailed log aided a lot to find the solution for me. In my case it was a mismatch between @PathVariable without name specified, and the variable itself.

Something like this:

@RequestMapping("/user/{uname}")
public String doSomething(@PathVariable String username) { ...

Note the difference between "uname" and "username" ! There was an exception internally that wasn't raised and I couldn't see it until I set the log to INFO level.

In my case the reason of this error was that browser (Chrome, in my particular case) was sending the date from the <input type="date" ... /> to the server in the wrong format so server didn't know how to parse it.
