一个让人莫名其妙的问题----------架构STRUTS,工具ECLIPSE
这是我的文件内容
ACTIONFORM内容:

下面是我的ACTION的内容

*/

import cn.hxex.huge.struts.form.FriendsForm;
/**

*/
public class FriendsAction extends Action {
/*
* Generated Methods
*/
/**
* Method execute
* @param mapping
* @param form
* @param request
* @param response
* @return ActionForward
*/
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
FriendsForm friendsForm = (FriendsForm) form;// TODO Auto-generated method stub
return mapping.findForward( "friends ");
}
}
下面是我的INPUT文件内容(FRIENDS.JSP)
<%@ page language= "java " pageEncoding= "ISO-8859-1 "%>
<%@ taglib uri= "http://jakarta.apache.org/struts/tags-bean " prefix= "bean "%>
<%@ taglib uri= "http://jakarta.apache.org/struts/tags-html " prefix= "html "%>
<html>
<head>
<title> JSP for FriendsForm form </title>
</head>
<body>
<html:form action= "/friends ">
Who are you friends:
friends 1 : <html:text property= "name[0] " /> <br>
friends 2 : <html:text property= "name[1] " /> <br>
friends 3 : <html:text property= "name[2] " /> <br>
They are address:
address 1 : <html:text property= "address[0] " /> <br>
address 2 : <html:text property= "address[1] " /> <br>
address 3 : <html:text property= "address[2] " /> <br>
<html:submit/>
</html:form>
</body>
</html>
下面是我的输出页面内容(PRINTFRIENDS.JSP)

<head>
<html:base />
<title> PrintFriends.jsp </title>
</head>
<body>
You are ${fn:length(friendsForm.names)} friends: <br>
<c:set var= "count " value= "0 " />
<c:forEach var= "friend " items= "${fn:length(friendsForm.names)} ">
<c:set var= "count " value= "${count+1} " />
friends ${count} : <bean:write name= "friendsForm " property= "name[${count}] "/>
</c:forEach>
They are address:
<c:set var= "count " value= "0 " />
<c:forEach var= "friend " items= "${fn:length(friendsForm.addresses)} ">
<c:set var= "count " value= "${count+1} " />
address ${count} : <bean:write name= "friendsForm " property= "address[${count}] "/>
</c:forEach>
</body>
</html:html>
下面是我的STRUTS-CONFIG相关配置
<form-beans >
<form-bean name= "friendsForm " type= "cn.hxex.huge.struts.form.FriendsForm " />
</form-beans>
.......
<action-mappings >
<action
attribute= "friendsForm "
input= "/form/friends.jsp "
name= "friendsForm "
path= "/friends "
scope= "request "
type= "cn.hxex.huge.struts.action.FriendsAction " >
<forward name= "friends " path= "/PrintFriends.jsp " />
</action>
</action-mappings>
[解决办法]
text 的值也可以用数组来表示么？
