在struts环境中使用validation框架出现ServletException的问题。

[sui102]

服务器是resin3.0.8，在显示页面表单的时候报错。

页面报错信息：

<html:javascript formName="uploadRecordsForm" dynamicScript="true" staticScript="false"/>

这种方法没有用，一样是报错。

[sui102]

我机器上运行struts自带的例子，一点问题都没有。
我把自己的Jsp拷贝到struts自带的例子应用里面去，添加相应的配置以后，访问的时候，报一样的错。
真是郁闷！！

[albert2000]

你有没有在struts-config.xml中,
在action中,把validate="true"该为validate="false"
你原来是用服务器端验证的,validate是应该等于ture,现在你是用客户断验证的,改为false

[albert2000]

说错了!!!不对!

[albert2000]

楼主,你跟踪进去看看有没有运行到action里面?

[sui102]

当然有，我用的是ForwardAction
配置如下：
<action path="/showUploadRecordsForm"
type="org.apache.struts.actions.ForwardAction"
parameter="uploadRecordsPage"
validate="false"/>

就是在生成页面的时候出的问题。也就是说，还没等到提交表单，在显示表单的时候出错的。

[albert2000]

<action path="/showUploadRecordsForm"
type=""
name="uploadRecordsForm"
scope="request"
input="/showUploadRecordsForm"
validate="true">
<forward name="success" contextRelative="true" path=""/>
</action>
你在action中指定你要映射的form

[sui102]

我的Jsp页面：
<%@ page contentType="text/html;charset=GBK" language="java" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<html:html>
<html:messages id="msg" message="true" bundle="phoneRecord">
<bean:write name="msg"/><br/>
</html:messages>

<html:errors bundle="phoneRecord"/>
<html:javascript formName="uploadRecordsForm"/>
<html:form method="post" action="uploadRecords.do"
enctype="multipart/form-data" onsubmit="return validateUploadRecordsForm(this);">
<bean:message key="label.phoneRecord.upload.select" bundle="phoneRecord"/>
<html:file property="file"/> <html:submit/>

</html:form>

</html:html>

validation.xml文件片段：
<form name="uploadRecordsForm">
<field property="file" depends="required">
<msg name="required" key="label.phoneRecord.upload.noFile"/>
</field>
</form>

struts-config.xml文件片段：
<form-bean
name="uploadRecordsForm"
type="org.apache.struts.validator.DynaValidatorForm">
<form-property
name="file"
type="org.apache.struts.upload.FormFile"/>
</form-bean>

在只采用服务器端校验的时候一切正常，在使用客户端校验的时候，整个页面不能显示。

[albert2000]

<html:javascript formName="uploadRecordsForm" dynamicScript="true" staticScript="false"/>

[sui102]

我用的是ForwardAction，应该不需要指定映射的Form吧？

可能是jar版本的问题，重新换一下看看。
