JSP Error: According to TLD, tag form:input must be empty, but is not

I try to create form in JSP and have one problem with input field. Here is part of my JSP page:

<section>
    <div class="container">
        <h4>Add new PC or Laptop</h4>
        <div class="form">
            <form:form method="post" action="/app/pc/add" class="form-horizontal" modelAttribute="pc" role="form">
                <div class="control-group">
                    <label class="control-label" for="number">PC Number</label>
                    <div class="controls">
                        <form:input id="number" placeholder="Number" path="number">
                    </div>
                </div>
                <div class="control-group">
                    <label class="control-label" for="cpu">CPU</label>
                    <div class="controls">
                        <form:input id="cpu" placeholder="CPU" path="cpu">
                    </div>
                </div>
                <div class="control-group">
                    <label class="control-label" for="hdd">HDD size</label>
                    <div class="controls">
                        <form:input id="hdd" placeholder="HDD size" path="hdd">
                    </div>
                </div>
                <div class="control-group">
                    <label class="control-label" for="os">OS</label>
                    <div class="controls">
                        <form:select id="os" path="os">
                            <c:forEach items="<%=com.springapp.mvc.entities.OpSystem.values()%>" var="value">
                                <option value="${value}">${value}</option>
                            </c:forEach>
                        </select>
                    </div>
                </div>
                <div class="control-group">
                    <label class="control-label" for="office">Office</label>
                    <div class="controls">
                        <form:input id="office" placeholder="Office version" path="office">
                    </div>
                </div>
                <div class="control-group">
                    <div class="controls">
                        <form:button type="submit" class="btn">Save</button>
                    </div>
                </div>

            </form>
        </div>
    </div>
</section>

And here is my Controller class:

package com.springapp.mvc.controllers;

import com.springapp.mvc.entities.ComputerRepository;
import com.springapp.mvc.entities.OpSystem;
import com.springapp.mvc.entities.Pc;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
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 org.springframework.web.servlet.ModelAndView;

/**
 * Created by aleksandrs on 12/27/13.
 */
@Controller
@RequestMapping("/app")
public class AppController {
    @Autowired
    private ComputerRepository repository;

    @RequestMapping("/")
    public ModelAndView getIndex(){
        ModelAndView model = new ModelAndView("index");
        model.addObject("act","");
        return model;
    }

    @RequestMapping(value = "/pc/list")
    public ModelAndView getPCList(){
        ModelAndView model = new ModelAndView("index");
        model.addObject("act","devices");
        model.addObject("include","pc_list");
        model.addObject("list",repository.findAll());
        return model;
    }

    @RequestMapping(value = "/pc/add", method = RequestMethod.GET)
    public ModelAndView addPc(){
        ModelAndView model = new ModelAndView("index");
        model.addObject("include","pc_add");
        model.addObject("act","devices");
        model.addObject("osTypes", OpSystem.values());
        return model;
    }

    @RequestMapping(value = "/pc/add", method = RequestMethod.POST)
    public ModelAndView savePc(@ModelAttribute("pc") Pc pc, BindingResult result){
        repository.save(pc);
        return new ModelAndView("redirect:/app/pc/list");
    }

}

And here is an Error:

You forgot to close your input tags:

<form:input id="hdd" placeholder="HDD size" path="hdd">

should be

<form:input id="hdd" placeholder="HDD size" path="hdd" />

Also note that the following is invalid:

<form:button type="submit" class="btn">Save</button>

The closing tag (</button>) must match the opening tag (<form:button>)
