Error on View - MultiActionController + Spring:bine

[Twoz Lee]

I would like to add validation later on, so i have added spring:bind tag from original jsp page. However, the view can not find the object of command.login_id

so what can i do ?

JSP - test.jsp

    

<%@ page language="java" contentType="text/html; charset=BIG5" pageEncoding="BIG5"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form" %>
 
aaaaaaaaaaaaaaaaaa   
    
    <spring:bind path="command.login_id">
       <input type="text" 
                    name="${status.expression}" 
                    value="${status.value}"/><br> 
        
         <font color="red">
          <c:if test="${status.error}">
                Error codes:
                <c:forEach items="${status.errorMessages}" var="error">
                    <c:out value="${error}"/>
                </c:forEach>
          </c:if>
  </font><br>
    </spring:bind> 

Controller (MultiActionController)

   

public class TestControl extends MultiActionController{
 
   public ModelAndView TestPage(HttpServletRequest req, HttpServletResponse res){
  return new ModelAndView("base/member/test");
   }
 
}

 

Spring_mvc_config.xml

<bean id="TestControl" class="base.mvc.control.TestControl ">          
      <property name="validators">
      <list>
        <bean class="base.mvc.validator.TestValidator" />
      </list>
    </property>
    
</bean>

Where do you define what object is behind the binding?

I don't see that anywhere.

Also, do you have to use an older version of Spring. In Spring 2.5 and especially Spring 3.0, Controllers don't implement or extend Spring Controller classes anymore. And binding is more automatic.

I have a very similar problem, so i will ask a question here.
How should be defined then command object, when im using MultiActionController.
In my application, form looks like this:

 <form:form action="create.htm" commandName="room">
(...)
<form:form>

Controller:

public class NewRoomController extends MultiActionController {
(...)
   public ModelAndView create(HttpServletRequest request,
            HttpServletResponse response, Room room) throws Exception {
        (...)
        return new ModelAndView("created");
    }
}

And container throws:

javax.servlet.jsp.JspTagException: Neither BindingResult nor plain target object for bean name 'room' available as request attribute

Some ideas?
