google app engine - Spring-MVC forms on GAE -
i trying create form using spring framework, according (http://groups.google.com/group/google-appengine-java/ browse_thread/thread/d93fd7385bf85bf7), need override initbinder. well, think did , 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 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 instead? } public void setproductmanager() {...} public productmanager getproductmanager {...} } finally, priceincreaseeditor.java: (this wrong..)
public class priceincreaseeditor extends propertyeditorsupport{ @override public void setastext(string text) throws illegalargumentexception { integer increase = new integer(text); super.setvalue(increase); } } stack trace:

simpleformcontroller.initbinder() takes (httpservletrequest request, servletrequestdatabinder binder) while initbinder() takes arguments in opposite order.
so haven't overridden it. try switching order of arguments. , whenever intend override anything, put @override on compiler can catch mistakes 1 you.
