STRUTS框架不能创建FORMBEAN错误

[mingyun310]

<ERROR> [org.apache.struts.util.RequestUtils] - Error creating form bean of class com.lenovo.sdm.regweb.web.forms.ReguditingForm
java.lang.NullPointerException
我遇到了个这个错误。说不能创建FORMBEAN。不知是什么原因引起的。望高手给以指点。
我的配置文件是：<form-beans>
<form-bean name="regAuditingForm" type="com.lenovo.sdm.regweb.web.forms.ReguditingForm"></form-bean>
</form-beans>
FORMBEAN也编译了。

package com.lenovo.sdm.regweb.web.forms;

public class RegAuditingForm extends ActionForm {

很明显
<form-bean name="regAuditingForm" type="com.lenovo.sdm.regweb.web.forms.ReguditingForm"></form-bean>
里面ReguditingForm这个类名写错了，少了个A

lz要仔细啊，如果是手写XML的话。也可以用eclipse的插件，比如MyEclipse什么的生成配置的XML文档，安全多了，至少不会犯这种错误
