当我尝试读取 JSF 页面中的属性文件时，我从服务器收到 HTTP 500 错误。虽然从类文件中读取 Bundle 是有效的。

下面是我的示例 webapp 的结构，它是 Tomcat 中的一个 osgi 包。清单文件中的类路径是 web/WEB-INF/classes。所以资源包已经存在于类路径中

Sample
    META-INF  ---> MANIFEST.MF
    web             
        App
           home.jsp
        login.jsp
        index.html
        WEB-INF
           web.xml
           faces-config.xml
           classes-->myresource.properties
           lib------>packaged jar

下面是我的 home.jsp 文件的内容，该文件位于 Sample/web/App 目录中。

<f:loadBundle var="bundle" basename="com.obj.colours" /> 
<f:loadBundle var="addonpages" basename="CustomAddonPages" />
.
.
<h:outputText value='#{brandingBundle["label.ManagementConsole"]}' />
<!-- <a href="../CustomReport.faces">Custom Reporting </a> -->

<!-- below part gives error and i have to use the above hard 
    coded way using anchor tag-->

<h:commandLink action="#{addonpages.Redirectpage}">            
      <h:outputText value="Custom Reporting"/>              
</h:commandLink>

属性文件包含一行

      Redirectpage=../CustomReport.faces

服务器的错误如下

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

You get a MethodNotFoundException so the class is found but the method does not exist. Maybe the method must be public?

我真的很抱歉首先犯了一个严重的错误，然后回答我自己的问题。如果我向您展示了整个页面源代码，您的专家可能已经猜对了。

It is not possible to use h:commandLink when NOT present inside the form element and i should have used h:outputLink

但是，当我第一次修改页面并使用 commandLink 时，抛出的错误并不那么清楚，正如 Balazs 回答的那样，我必须利用方法表达式在 commandLink 的 action 属性中使用。所以我继续创建自己的 ResourceBundle 类，然后在这个资源包中读取我的 .properties，但我仍然面临同样的问题。

我尝试的下一件事不是修改供应商提供的 webapp，而是在 eclipse 中创建了一个示例应用程序并在那里进行了测试。而这一次，Eclipse 足够大方地显示带有 commandLink 空间的页面，显示该行 - commandLink can only be used when present inside form element

所以现在我正在使用 outputLink 并加载 .properties 文件包，它工作得很好。
