Make sure that your Spring form mentions the modelAttribute="<Model Name".

Example:

@Controller
@RequestMapping("/greeting.html")
public class GreetingController {

 @ModelAttribute("greeting")
 public Greeting getGreetingObject() {
  return new Greeting();
 }

 /**
  * GET
  * 
  * 
  */
 @RequestMapping(method = RequestMethod.GET)
 public String handleRequest() {
  return "greeting";
 }

 /**
  * POST
  * 
  * 
  */
 @RequestMapping(method = RequestMethod.POST)
 public ModelAndView processSubmit(@ModelAttribute("greeting") Greeting greeting, BindingResult result){
  ModelAndView mv = new ModelAndView();
  mv.addObject("greeting", greeting);  
  return mv;
 }
}

In your JSP :

<form:form  modelAttribute="greeting" method="POST" action="greeting.html">

I worked on this same issue and I am sure I have found out the exact reason for it.

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

If your successView property value (name of jsp page) is the same as your input page name, then second value of ModelAndView constructor must be match with the commandName of the input page.

E.g.

index.jsp

<html>
<body>
    <table>
        <tr><td><a href="Login.html">Login</a></td></tr>
    </table>
</body>
</html>

dispatcher-servlet.xml

<bean id="viewResolver"
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">

    <property name="prefix">
        <value>/WEB-INF/jsp/</value>
    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
</bean>
<bean id="urlMapping"
    class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    <property name="urlMap">
        <map>              
            <entry key="/Login.html">
                <ref bean="userController"/>
            </entry>
        </map>          
    </property>             
</bean>     
 <bean id="userController" class="controller.AddCountryFormController">     
       <property name="commandName"><value>country</value></property>
       <property name="commandClass"><value>controller.Country</value></property>        
       <property name="formView"><value>countryForm</value></property>
       <property name="successView"><value>countryForm</value></property>
   </bean>

AddCountryFormController.java

package controller;

import javax.servlet.http.*;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.validation.BindException;
import org.springframework.web.servlet.mvc.SimpleFormController;


public class AddCountryFormController extends SimpleFormController
{

    public AddCountryFormController(){
        setCommandName("Country.class");
    }

    protected ModelAndView onSubmit(HttpServletRequest request,HttpServletResponse response,Object command,BindException errors){

            Country country=(Country)command;

            System.out.println("calling onsubmit method !!!!!");

        return new ModelAndView(getSuccessView(),"country",country);

    }

}

Country.java

package controller;

public class Country
{
    private String countryName;

    public void setCountryName(String value){
        countryName=value;
    }

    public String getCountryName(){
        return countryName;
    }

}

countryForm.jsp

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
<html>
<body>
    <form:form commandName="country" method="POST" >
            <table>
                    <tr><td><form:input path="countryName"/></td></tr>
                    <tr><td><input type="submit" value="Save"/></td></tr>
            </table>
    </form:form>
</body>
<html>

Input page commandName="country" ModelAndView Constructor as return new ModelAndView(getSuccessView(),"country",country); Means inputpage commandName==ModeAndView(,"commandName",)

Try adding a BindingResult parameter to methods annotated with @RequestMapping which have a @ModelAttribute annotated parameters. After each @ModelAttribute parameter, Spring looks for a BindingResult in the next parameter position (order is important).

So try changing:

@RequestMapping(method = RequestMethod.POST)
public String loadCharts(HttpServletRequest request, ModelMap model, @ModelAttribute("sideForm") Chart chart) 
...

To:

@RequestMapping(method = RequestMethod.POST)
public String loadCharts(@ModelAttribute("sideForm") Chart chart, BindingResult bindingResult, HttpServletRequest request, ModelMap model) 
...

We faced the same issue and changed commandname    to modelAttribute    in jsp page to solve this issue

Make sure you declare the bean associated with the form in GET method of the associated controller and also add it in the model model.addAttribute("uploadItem", uploadItem); which contains @RequestMapping(method = RequestMethod.GET) annotation.

For example UploadItem.java is associated with myform.jsp and controller is SecureAreaController.java

myform.jsp contains

<form:form action="/securedArea" commandName="uploadItem" enctype="multipart/form-data"></form:form>

MyFormController.java

@RequestMapping("/securedArea")
@Controller
public class SecureAreaController {

@RequestMapping(method = RequestMethod.GET)
public String showForm(Model model) {
            UploadItem uploadItem = new UploadItem(); // declareing

            model.addAttribute("uploadItem", uploadItem); // adding in model
    return "securedArea/upload";
}

}

As you can see I am declaring UploadItem.java in controller GET method.

[spring] Neither BindingResult nor plain target object for bean name available as request attr

The answer is

MyFormController.java
