目前我的页面正在返回错误，因为我已经开始在JSP环境中实现XPM。组件链接似乎是这里的问题。它几天前工作正常，现在我们不断得到这些Tomcat错误：

奇怪的是，普通JSP文件中的组件链接就在那里，包括PageURI。：
<tridion:ComponentLink runat="server" PageURI="tcm:17-480-64" ComponentURI="tcm:17-795" TemplateURI="tcm:0-0-0" AddAnchor="false" LinkText="<img src="/Images/women_edfd8f3453414ade82b7becaa0790386.jpg" alt="Woman #1">" LinkAttributes="" TextOnFail="true"/>
以及将cd_tags lib正确地包含在每个单独的页面模板中，以及适当的核心引用：
<%@ page contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>
<%@ taglib uri="cd_tags" prefix="tridion" %>
我尝试过搜索错误，但没有Tridion特定于上下文的解决方案。我目前正在考虑重置/重新配置组件链接，但我不完全确定首先配置中是否有任何错误。任何想法都会很棒。
答案 0 :(得分：3)
该链接用于.NET控件 - 而不是JSP标记库。
也许有人更改了您正在使用的发布目标上的目标语言（或者它已发布到错误的目标）？另一种可能性是它在模板中是硬编码的，而不是使用TCDL。
答案 1 :(得分：0)
感谢Peter Kjaer指点我的方向，这个问题现在已经解决了。然而，这不是由于出版目标和语言（因为它们设置正确 - 但我不会完全排除pubtargets冲突的可能性。）
问题原来是HTTP上传服务器角色上的deployer_conf xml文件，其TCDLEngine节点中的（默认）行 - Properties。
<!--<Property Name="tcdl.dotnet.style" Value="controls"/>-->
<Property Name="tcdl.jsp.style" Value="tags"/>
如您所见，我评论了dotnet线。现在它将正确解析链接，以及不再包括'runat'的组件链接。
