我正在尝试运行“Core JavaServer Faces”书（http://horstmann.com/corejsf/）中的示例 ch05

登录后，我收到以下消息：

/sections/planetarium/sidebarLeft.xhtml @12,72 <corejsf:planet> null

Planet 是一个组合，位于 WEB-INF/tags/corejsf/planet.xhtml

corejsf.taglib.xml 是：

<?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>
  <namespace>http://corejsf.com/facelets</namespace>
  <tag>
    <tag-name>planet</tag-name>
    <source>tags/corejsf/planet.xhtml</source>
  </tag>
</facelet-taglib>

web.xml 包含以下文件：

<context-param>
  <param-name>facelets.LIBRARIES</param-name>
  <param-value>/WEB-INF/corejsf.taglib.xml</param-value>
</context-param>

调试时，我在查找“jndi:/server/planets/WEB-INF/tags/corejsf/planet.xhtml”时收到 FileNotFoundException。

在其他机器上我部署了同样的战争并且没有例外。

战争部署在 GlassFish4 上

我遇到了同样的问题，我的项目（Glassfish 4 + Spring + EJB 3 + JSF 2.2 + Custom Tags）在我的本地 Glassfish 和登台服务器上运行良好，但在生产上却抛出了异常TagException: /WEB-INF/templates/common.xhtml @38,33 <app:div> null。

经过大量调试，我们发现了问题所在。如果您的 Glassfish 配置了多个虚拟服务器，并且您的项目已部署并与 2 个或更多相关联，则 JSF lib 通过您正在访问它的当前主机名读取源文件，但是对于自定义 facelets 标签，它通过不同的虚拟服务器（可能是一个错误）并抛出一个FileNotFoundException（被 抑制TagException）。

如果您将部署的项目配置为仅一台虚拟服务器，则不会出现此问题。
