从JSF中的属性文件访问资源包osgi bundle webapp

Question

我在尝试读取JSF页面中的属性文件时从服务器收到HTTP 500错误。虽然从类文件中读取Bundle正在运行。

下面是我的Sample 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。因此，资源包已经存在在类路径

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 

下面是我回到Home.jsp文件的内容，其存在于样品/网络/应用程序目录。

<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> 

属性文件中包含一行

 Redirectpage=../CustomReport.faces 

来自服务器的错误是如下

type Exception report 

message 

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

Answer 1

因此该类发现你得到一个MethodNotFoundException但该方法不存在。也许该方法必须公开？

Answer 2

解决方案

我在第一个地方犯了严重的错误，然后回答我自己的问题真的很抱歉。可能你是专家可能已经猜对了，我告诉你整个页面源。

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

然而，当我第一次修改了页面，并使用了commandLink抛出的错误是不清晰和巴拉兹回答，我必须充分利用的方法表达了commandLink的action属性里面使用。所以我继续前进，创建了一个我自己的ResourceBundle类，然后在这个资源包中读取我的.properties，并且仍然面临同样的问题。

我试过的下一件事是，而不是修改供应商提供的webapp，我在eclipse中创建了一个示例应用程序，并在那里进行测试。这一次，Eclipse足够慷慨地显示带有commandLink空间的页面，显示该行 - commandLink can only be used when present inside form element

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