在web.xml中，我對全局錯誤頁面具有以下配置。正在處理的頁面在錯誤/異常中僅留下一半空白，而不是轉發到web.xml中指定的錯誤頁面
<error-page>
<error-code>401</error-code>
<location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>
<error-page>
<error-code>403</error-code>
<location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>
<error-page>
<error-code>404</error-code>
<location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>
<error-page>
<error-code>500</error-code>
<location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>
<error-page>
<error-code>503</error-code>
<location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>
當任何出現異常時（在500內部服務器錯誤結果），該請求被預期要被分派到指定的錯誤頁面，但是在發生異常時，正被處理的頁面只是留空在中途。它不轉發到錯誤頁面。
配置java.lang.Throwable或java.lang.Exception如下，
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/WEB-INF/error_pages/GeneralError.xhtml</location>
</error-page>
也沒了幫助。

也試過在一個空白的項目只有一個單一的XHTML頁面並沒有什麼比在web.xml錯誤頁面的配置等。當發生異常（其他HTTP狀態，只有404作品）時，頁面只是半透半邊，而不是轉發到錯誤頁面。
如何在發生任何異常/錯誤時分派到指定的錯誤頁面？
更新1：
根據this問題/答案，我添加上下文參數javax.faces.FACELETS_BUFFER_SIZE到web.xml中有64KB的緩衝區大小，但沒有新發生。如果發生異常，它仍然不會轉發到錯誤頁面。如果發生異常/錯誤，頁面只會被部分處理並在中途留空。異常堆棧跟蹤只能在服務器終端上找到，而不能在網頁上找到（如果500內部服務器錯誤）。如果它轉發到錯誤頁面，我故意讓應用程序拋出異常來查看。
更新2：
在編輯1中提到設置的緩衝區大小後，我得到了以下例外在某一時間（當在成功登錄後一請求被重定向到安全區域）。所以，我現在刪除了這個參數。

更新3：
我試圖增加緩衝區的大小（100002400那是太多了），直到錯誤java.lang.OutOfMemoryError: Java heap space發出。因此，輸出緩衝區大小不應該成爲問題。
通過OmniFaces - org.omnifaces.exceptionhandler.FullAjaxExceptionHandlerFactory在faces-config.xml中配置，可以在異步請求期間錯誤地正確呈現Ajaxical事件中的錯誤頁面。
也許，如果我在開始時配置了錯誤頁面，那麼可能會發現問題的原因 - 當我啓動應用程序時，應用程序因此沒有太多的額外開銷，它與許多XHTML頁面，CDI託管的bean，EJB會話bean等，但無論如何，我不知所措。
更新4：
我現在運行在WildFly 9.0.2最終相同的應用程序。問題沒有改變。
您是否在完全不同的容器中嘗試了這種方法？也許JBoss？ – kolossus 2014-12-02 15:49:24
它僅是GlassFish Server 4.1，它是部署到服務器的唯一應用程序。其他服務器在GlassFish運行時關閉。 @kolossus – Tiny 2014-12-02 16:12:33
我的要點是，你應該嘗試消除你的容器中的錯誤的可能性;嘗試將相同的應用程序部署到不同的容器 – kolossus 2014-12-02 16:17:19
