使用Facelets标记文件时出现FileNotFoundException

本文介绍了使用Facelets标记文件时出现FileNotFoundException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试从"Core JavaServer Faces"书中运行示例ch05( http://horstmann.com /corejsf/)

I'm trying to run the example ch05 from the "Core JavaServer Faces" Book (http://horstmann.com/corejsf/)

登录后，我收到以下消息:

After logging in I get the following message:

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

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

planet is a composition, residing under WEB-INF/tags/corejsf/planet.xhtml

corejsf.taglib.xml是:

The corejsf.taglib.xml is:

<?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包含文件:

The web.xml includes the file:

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

调试时，我在寻找"jndi:/server/planets/WEB-INF/tags/corejsf/planet.xhtml"时收到FileNotFoundException.

When debugging, I get a FileNotFoundException while looking for "jndi:/server/planets/WEB-INF/tags/corejsf/planet.xhtml".

在其他机器上，我进行了同样的战斗，也没有例外.

On other machines I deployed the same war and got no exception.

战争部署在GlassFish4上

The war is deployed on GlassFish4

推荐答案

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和一个登台服务器，但是在生产环境中它抛出了异常TagException: /WEB-INF/templates/common.xhtml @38,33 <app:div> null.

I was experiencing the same problem, my project (Glassfish 4 + Spring + EJB 3 + JSF 2.2 + Custom Tags) was running fine on my local Glassfish and on a staging server, but on Production it was throwing an exception 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，并且已部署项目并将其与2个或更多虚拟机关联，那么JSF库会通过您正在访问的当前主机名读取源文件，但是对于读取的自定义facelets标签，一个不同的虚拟服务器(可能是一个错误)并抛出一个FileNotFoundException(由抑制).

After a lot of debugging we found out the problem. If your Glassfish have more than one virtual server configured and your project is deployed and associated with 2 or more, the JSF lib reads the sources files through the current host name you are accessing it, however for custom facelets tags it reads through a different virtual server (probably a bug) and throws a FileNotFoundException (suppressed by TagException).

如果将部署的项目配置为仅一个虚拟服务器，则不会发生此问题.

If you configure your deployed project to only one virtual server, this problem does not occur.
