问题描述

我正在创建一个基于JSF 2.2（Mojarra）的应用程序。我使用的是Eclipse EE生成的EAR项目和动态Web项目以及Glassfish服务器。



我创建了一个Facelet标记文件，如https://stackoverflow.com/a/5716633/2266635 。当我加载一个包含标签的页面时，我得到这个错误（和一个HTTP 500错误）： 

  2014-03-24T00： 32：10.904 + 0100警告：StandardWrapperValve [Faces Servlet]：servlet的Servlet.service（）Faces Servlet抛出异常

我也尝试在上复制示例http://www.mkyong.com/jsf2/custom-tags-in-jsf-2-0/ ，我仍然收到错误（使用不同的标签）。

UserTagHandler.java第144行的错误是FileNotFoundException。如果我在taglib定义文件中提供一个无效文件为< source> ，我会得到相同的错误！所以它永远不会找到带有标签源代码的文件。

我不明白为什么Glassfish找不到我的登录表单.xhtml 。我尝试过不同的路径，甚至尝试了strace'ing玻璃鱼，但没有任何明智的结果...任何想法可能是错的什么？ 解决方案

问题出在服务器配置中。我找不到原因，但它在另一个Glassfish实例上工作，所以我刚刚删除了域并重新创建了它。对不起，我找不到更具体的东西。


I am creating an application based on JSF 2.2 (Mojarra). I am using a Java EE EAR project and a Dynamic Web project generated by Eclipse, and the Glassfish server.

I created a Facelet tag file as shown in https://stackoverflow.com/a/5716633/2266635 . When I load a page containing the tag I get this error (and a HTTP 500 error):

2014-03-24T00:32:10.904+0100|WARNING: StandardWrapperValve[Faces Servlet]: Servlet.service() for servlet Faces Servlet threw exception

I have also tried to copy the example at http://www.mkyong.com/jsf2/custom-tags-in-jsf-2-0/ verbatim, and I'm still getting the error (with a different tag).

The error at line 144 of UserTagHandler.java is a FileNotFoundException. If I supply an invalid file as <source> in the taglib definition file, I get the same error! So it never finds the file with the tag source code.

Here is a screenshot of the file tree: http://www.fa2k.net/misc/project.png (sorry, not allowed to post inline images yet)

        <h1>Custome Tags in JSF 2.0</h1>
        <fmk:login-form/>
    </h:body>
</html>

I don't understand why Glassfish can't find my login-form.xhtml . I have tried different paths and even tried strace'ing glassfish, but without any sensible results... Any ideas what could be wrong?

解决方案

The problem was in the server configuration. I couldn't find the cause, but it worked on a different Glassfish instance, so I just deleted the domain and re-created it. Sorry I couldn't find anything more specific.
