创建了taglib文件： PAC-taglibs.xhtml
<?xml version='1.0'?> <!DOCTYPE facelet-taglib PUBLIC "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN" "http://java.sun.com/dtd/facelet-taglib_1_0.dtd"> <facelet-taglib version="2.0"> <namespace>http://www.myproduct.com/jsf</namespace> <tag> <tag-name>pac-menu</tag-name> <source>/resources/tags/menu.xhtml</source> </tag> </facelet-taglib>
修改了web.xml y添加： 的web.xml
<context-param> <param-name>javax.faces.FACELETS_LIBRARIES</param-name> <param-value>/resources/taglibs/pac-taglibs.xhtml</param-value> </context-param>
在我的网页中引用了我的taglib，并使用如下标记： home.xhtml
<?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:a4j="http://richfaces.org/a4j" xmlns:rich="http://richfaces.org/rich" xmlns:a3c="http://www.myproduct.com/jsf"> <h:head> <link rel="stylesheet" type="text/css" ref="${facesContext.externalContext.requestContextPath}/resources/css/styles.css"/> <title>My Product V1.0 Beta</title> </h:head> <h:body styleClass="backGroundimage"> <center> <h:form> <h:outputText id="outtxt" styleClass="h1" value="Welcome ${pAC_USER.name}"/><BR/><BR/> <a3c:pac-menu/> </h:form> </center> </h:body> </html>
这是目录结构：
WebContent | ---> META-INF | ---> WEB-INF | ---> resources | | | ---> css | | | ---> taglibs | | | | | ---> pac-taglibs.xhtml | | | ---> tags | | | | | ---> menu.xhtml | ---> index.xhtml
每次我尝试访问我的页面时都会收到以下错误消息：

这是如何引起的？如何解决？
答案 0 :(得分：2)
我通过更改标记库中引用标记文件的方式对此进行了排序。
首先，我发现使用tomcat7而不是glassfish导致问题的文件，由于某种原因，它没有给出文件的名称。
然后在pac-taglib.xhtml中我改变了：
<source>/resources/tags/menu.xhtml</source>
带
<source>../tags/menu.xhtml</source>
但是，如果有人知道如何引用除相对参考之外的标签，我很高兴知道。 再次感谢那些花时间去搜索。 任何其他信息仍然欢迎。
