问题描述
我正在开发一个Web项目，我使用tile在一个jsp中包含多个jsp.
我遇到TilesIOException的问题.
I'm working on a web project and I use tiles to have multiple jsp's in one jsp.
I've encountered a problem where I get TilesIOException.
我有个名称为:mainpage.jsp的jsp，其中包含所有用于标题，正文和页脚的jsp. 我的身体还应该包含其他一些jsp，因此我也尝试在其中使用瓦片，但没有运气.
I have this jsp with the name: mainpage.jsp which contains all the jsp's for header, body and footer. My body here should also contain some other jsp's and therefore I'm trying to use tiles in that as well with no luck.
这是图块中的结构和xml代码.
Here's the structure and the xml code in tiles.
mainpage.jsp
----header.jsp
----body.jsp(mainpageBody.jsp)
--------bodybox1.jsp
--------bodybox2.jsp
--------bodybox3.jsp
--------bodybox4.jsp
----footer.jsp
tiles.xml:
tiles.xml:
<definition name="mainpage" extends="mainpageLayout">
<put-attribute name="title" value="Welcome" />
<put-attribute name="body" value="/mainpage/mainpageBody.jsp" />
<put-attribute name="mainbox0" value="/bodybox1.jsp" />
<put-attribute name="mainbox1" value="/bodybox2.jsp" />
<put-attribute name="mainbox2" value="/bodybox3.jsp" />
<put-attribute name="mainbox3" value="/bodybox4.jsp" />
</definition>
<definition name="mainpageLayout" template="/mainpage.jsp">
<put-attribute name="title" value="Template" />
<put-attribute name="header" value="/mainpage/header.jsp" />
<put-attribute name="body" value="/mainpage/body.jsp" />
<put-attribute name="footer" value="/mainpage/footer.jsp" />
</definition>
她是我的mainpageBody.jsp:
Her is my mainpageBody.jsp:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<%@ page import="java.text.*,java.util.*"%>
<script type="text/javascript">
function showRegisterUserPage() {
$(".frontpageBodyContent").load("showRegisterPageRegisterAction");
}
</script>
<div class="frontpageBodyContent">
<div id="frontPageContentDiv">
<table border="0" style="width:100%">
<tbody>
<tr>
<td>
<div id="bodybox1">
<tiles:insertAttribute name="bodybox1" />
</div>

<td>
<div id="bodybox2">
<tiles:insertAttribute name="bodybox2" />
</div>
</td>
</tr>
<tr>
<td>
<div id="bodybox3">
<tiles:insertAttribute name="bodybox3" />
</div>
</td>
<td>
<div id="bodybox4">
<tiles:insertAttribute name="bodybox4" />
</div>
</td>
</tr>
</tbody>
</table>
</div>
</div>
WEB-INF文件夹包含:lib文件夹，tiles.xml& web.xml. lib文件夹不包含任何内容.
WEB-INF folder contains: lib folder, tiles.xml & web.xml. lib folder doesn't contain anything.
struts.xml:
struts.xml:
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd">

<action name="registrering" method="showRegisterUserPage" class="com.x.web.action.RegisterAction">

</package>
web.xml:

</javaee:listener-class>
</listener>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
我得到例外:
org.apache.tiles.TilesException:
ServletException including path '/templates/mainpage.jsp'.
org.apache.tiles.util.TilesIOException: JSPException including path '/content/mainpage/mainpageBody.jsp'.
org.apache.tiles.TilesException: Attribute 'bodybox1' not found.
我做错了什么? 非常感谢您的帮助，谢谢您！
What am I doing wrong? Help would be highly appreciated, thanks on advance!
推荐答案
尝试一下web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<display-name>X</display-name>
<listener>
<listener-class>org.apache.struts2.tiles.StrutsTilesListener</listener-class>
</listener>
<context-param>
<param-name>tilesDefinitions</param-name>
<param-value>/WEB-INF/tiles.xml</param-value>
</context-param>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
，然后检查WEB-INF文件夹中的tiles.xml.
and check that tiles.xml in WEB-INF folder.
