You have errors in the JSP page, some values are not initialized. — Roman C, Feb 05 '16 at 13:25

Your configuration is right, however, you have an issue in your controller such that, the controller responsible for returning the view should return a ModelAndView instance. Upon receiving a request, any BaseCommandController will attempt to fill the command object using the request parameters. This is done using the typical and well-known JavaBeans property notation. When a request parameter named 'firstName' exists, the framework will attempt to call setFirstName([value]) passing the value of the parameter. Nested properties are of course supported. For instance a parameter named 'address.city' will result in a getAddress().setCity([value]) call on the command class. The form-tags default model attribute command. You should replace your controller with the code below:

    @RequestMapping(method = RequestMethod.GET, value = "/")
public ModelAndView personForm(Locale locale, Model model) {
    return new ModelAndView("home","command", new User());
}

"home" is the view you are directing to "command" is a default model attribute "new User()" is the instance which contains setters and getters for its properties. In the view that contain the form you have to make sure that the path attributes's value should have setters and getters in the User class.<form:input path="firstName" />, for example firstName should be equal to the firstName attribute in the User class moreover it should have setters and getters.

Reference: https://docs.spring.io/spring-framework/docs/1.2.9/javadoc-api/org/springframework/web/servlet/mvc/BaseCommandController.html
