Hello.

I am a newby in Spring MVC. So sorry about any mistake and about the so basic question I'm searching help for :S. I installed all the framework following the step by step we can find at springframework.org site.

It is a very silly hello.jsp, with list (furniture) controlled by a InventoryController, wich implements Controller, and a increaseprice.jsp, controlled by a PriceIncreaseFormController, wich extends from SimpleFormController, with a very simple form for increasing the price of all items in data base. Here you have both jsps:

Code:
<html>
  <head><title><fmt:message key="title"/></title></head>
  <body>
    <h1><fmt:message key="heading"/></h1>
    <p><fmt:message key="greeting"/> <c:out value="${model.now}"/></p>
    <h3>Products</h3>
    <c:forEach items="${model.products}" var="prod">
      <c:out value="${prod.description}"/> <i>$<c:out value="${prod.price}"/></i><br><br>
    </c:forEach>
    <br>
    <a href="<c:url value="priceincrease.htm"/>">Increase Prices</a>
    <br>
  </body>
</html>
Code:
<html>
<head>
  <title><fmt:message key="title"/></title>
  <style>
    .error { color: red; }
  </style>  
</head>
<body>
<h1><fmt:message key="priceincrease.heading"/></h1>
<form:form method="post" commandName="priceIncrease">
  <table width="95%" bgcolor="f8f8ff" border="0" cellspacing="0" cellpadding="5">
  <tr>
    <h3>Products</h3>
    <c:forEach items="${model.products}" var="prod">
      <c:out value="${prod.description}"/> <i>$<c:out value="${prod.price}"/></i><br><br>
    </c:forEach>
  </tr>
    <tr>
      <td align="right" width="20%">Increase (%):</td>
        <td width="20%">
          <form:input path="percentage"/>
        </td>
        <td width="60%">
          <form:errors path="percentage" cssClass="error"/>
        </td>
    </tr>
  </table>
  <br>
  <input type="submit" 
</form:form>
<a href="<c:url value="hello.htm"/>">Home</a>
</body>
</html>
Everything works fine.

Now I'm trying to improve a little its functionality. I want the list and the form in the same jsp. So something like this:

Code:
<form:form method="post" commandName="priceIncrease">
  <table width="95%" bgcolor="f8f8ff" border="0" cellspacing="0" cellpadding="5">
  <tr>
    <h3>Products</h3>
    <c:forEach items="${model.products}" var="prod">
      <c:out value="${prod.description}"/> <i>$<c:out value="${prod.price}"/></i><br><br>
    </c:forEach>
  </tr>
    <tr>
      <td align="right" width="20%">Increase (%):</td>
        <td width="20%">
          <form:input path="percentage"/>
        </td>
        <td width="60%">
          <form:errors path="percentage" cssClass="error"/>
        </td>
    </tr>
  </table>
  <br>
  <input type="submit" align="center" value="Increase" name="Increase">
</form:form>
Somehow I don't get this to show any product at the product list. Kind of I am not putting in the model the list of products I get from persistence.

The question is: the controller of the view "priceincrease.htm" should be a SimpleFormController or a Controller or a MultiactionController or what?

Now it is a SimpleFormController, but I don't get it how to request from persistence the product list before the jsp shows it up.

Is there any method I could overwrite in SimpleFormController, that could execute before the view, so I can previously load the product list? I tried with HandleRequest, but I get all the time the following error:

Code:
Neither BindingResult nor plain target object for bean name 'priceIncrease' available as request attribute
There you have the springapp-servlet.xml:

Code:
    <bean name="/hello.htm" class="springapp.web.InventoryController">
        <property name="productManager" ref="productManager"/>
    </bean>

    <bean name="/priceincrease.htm" class="springapp.web.PriceIncreaseFormController">
        <property name="productManager" ref="productManager"/>
        <property name="sessionForm" value="true"/>
        <property name="commandName" value="priceIncrease"/>
        <property name="commandClass" value="springapp.service.PriceIncrease"/>
        <property name="validator">
            <bean class="springapp.service.PriceIncreaseValidator"/>
        </property>
        <property name="formView" value="priceincrease"/>
        <property name="successView" value="priceincrease.htm"/>
    </bean>

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property>
        <property name="prefix" value="/jsp/"></property>
        <property name="suffix" value=".jsp"></property>        
    </bean>
As you can see... I really have a mess in my head :S. Some help, please.

Thank you,

Pedro
