I am trying to create a form using the Spring Framework, but according to this (http://groups.google.com/group/google-appengine-java/ browse_thread/thread/d93fd7385bf85bf7), I need to override initBinder. Well, I think I did that and it still doesn't work.
My jsp (priceincreasejsp):
<%@ page contentType="text/html;charset=UTF-8" language="java"
isELIgnored="false" session="false" %>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/
form" %>
<form:form method="post" commandName="priceIncrease">
Increase (%): <form:input path="percentage"/>
<input type="submit" value="Execute">
</form:form>
myapp-servlet.xml has the following:
<bean name="/priceincrease.htm"
class="myapp.web.PriceIncreaseFormController">
<property name="sessionForm" value="true"/>
<property name="commandName" value="priceIncrease"/>
<property name="commandClass" value="myapp.service.PriceIncrease"/
>
<property name="validator">
<bean class="myapp.service.PriceIncreaseValidator"/>
</property>
<property name="formView" value="priceincrease"/>
<property name="successView" value="success.htm"/>
<property name="productManager" ref="productManager" />
</bean>
PriceIncrease.java:
public class PriceIncrease implements Serializable {
private Integer percentage;
public void setPercentage(Integer i) {
percentage = i;
}
public Integer getPercentage() {
return percentage;
}
}
PriceIncreaseFormController.java:
public class PriceIncreaseFormController extends SimpleFormController
{
private ProductManager productManager;
public ModelAndView onSubmit(Object command) throws
ServletException {
PriceIncrease priceIncrease = (PriceIncrease) command;
Integer increase = priceIncrease.getPercentage();
productManager.increasePrice(increase);
return new ModelAndView(new RedirectView(getSuccessView()));
}
public void initBinder(WebDataBinder binder, WebRequest request)
{
binder.registerCustomEditor(PriceIncrease.class, new
PriceIncreaseEditor());
binder.registerCustomEditor(Integer.class,
new CustomNumberEditor(Integer.class, true)); // use this instead?
}
public void setProductManager() {...}
public ProductManager getProductManager {...}
}
Finally, PriceIncreaseEditor.java: (this is probably wrong..)
public class PriceIncreaseEditor extends PropertyEditorSupport{
@Override
public void setAsText(String text) throws IllegalArgumentException
{
Integer increase = new Integer(text);
super.setValue(increase);
}
}

I've been pretty stuck for a while now... Any ideas?
