從JSF中的屬性文件訪問資源包osgi bundle webapp

Question

我在嘗試讀取JSF頁面中的屬性文件時從服務器收到HTTP 500錯誤。雖然從類文件中讀取Bundle正在運行。

下面是我的Sample webapp的結構，它是Tomcat中的一個osgi包。清單文件中的類路徑是web/WEB-INF/classes。因此，資源包已經存在在類路徑

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文件的內容，其存在於樣品/網絡/應用程序目錄。

<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> 

屬性文件中包含一行

 Redirectpage=../CustomReport.faces 

來自服務器的錯誤是如下

type Exception report 

message 

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

Answer 1

因此該類發現你得到一個MethodNotFoundException但該方法不存在。也許該方法必須公開？

Answer 2

解決方案

我在第一個地方犯了嚴重的錯誤，然後回答我自己的問題真的很抱歉。可能你是專家可能已經猜對了，我告訴你整個頁面源。

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

然而，當我第一次修改了頁面，並使用了commandLink拋出的錯誤是不清晰和巴拉茲回答，我必須充分利用的方法表達了commandLink的action屬性裏面使用。所以我繼續前進，創建了一個我自己的ResourceBundle類，然後在這個資源包中讀取我的.properties，並且仍然面臨同樣的問題。

我試過的下一件事是，而不是修改供應商提供的webapp，我在eclipse中創建了一個示例應用程序，並在那裏進行測試。這一次，Eclipse足夠慷慨地顯示帶有commandLink空間的頁面，顯示該行 - commandLink can only be used when present inside form element

所以現在我使用outputLink並加載.properties文件包，它工作得很好。
