Class org.omnifaces.exceptionhandler.FullAjaxExceptionHandlerFactory是沒有javax.faces.context.ExceptionHandlerFactory

Question

我試圖通過url訪問我的應用程序時不斷收到此異常。與我的一所大學完全相同的配置。

下面是一些我在我的應用程序的配置：

faces-config.xml中

<factory> 
    <exception-handler-factory>org.omnifaces.exceptionhandler.FullAjaxExceptionHandlerFactory</exception-handler-factory> 

的web.xml

<error-page> 
     <exception-type>javax.faces.application.ViewExpiredException</exception-type> 
     <location>/logout.xhtml</location> 
    </error-page> 

    <error-page> 
     <error-code>403</error-code> 
     <location>/errorGeneral.xhtml</location> 
    </error-page> 

    <error-page> 
     <error-code>404</error-code> <!-- Not Found --> 
     <location>/errorGeneral.xhtml</location> 
    </error-page> 

    <error-page> 
     <error-code>408</error-code> <!-- Timeout --> 
     <location>/logout.xhtml</location> 
    </error-page> 

    <error-page> 
     <error-code>500</error-code> 
     <location>/errorGeneral.xhtml</location> <!-- Internal Server Error --> 
    </error-page> 

，在這裏異常的完整的堆棧：

我的工作：

的Websphere 7 RAD 9.1.1 JDK 8

任何關於我的問題是什麼？

謝謝。

它看起來像你的應用程序正在挑選兩個單獨的JSF實現 - 當然有異常中的OmniFaces類，但MyFaces顯示在堆棧中（很可能由服務器加載）。

最簡單的答案就是從您的應用程序中刪除JSF內容，並依賴於服務器中打包的版本 - 如果沒有多個實現，則無法在多個實現之間發生衝突。如果你特別依賴於OmniFaces，那麼你需要確保你在應用程序中包含完整的API +實現，使用PARENT_LAST類加載（或者一個獨立的共享庫），並且消除對MyFaces的任何引用從您的應用程序代碼實施並構建工件。
