我在我的網絡應用程序中打開其中一個頁面時出現一個非常奇怪的錯誤。該應用程序構建在Seam 2.2上,並在表示層中使用JSF(RichFaces)。我在Tomcat 6javax.servlet.ServletException - 我怎麼能找到原因?

運行在日誌一切看起來很好 - 每下一個JSF階段正常執行,最後一個後,當請求了Seam調試頁面的處理開始有這一刻......

這是堆棧跟蹤我看到調試頁上(沒有被記錄):

異常請求處理過程中: 通過與消息javax.servlet.ServletException引起:「的Servlet執行引發異常」

異常,沒有任何原因......

我試圖抓住我的自定義過濾器(LoggingFilter.java,你可以在STRACK跡見)外,使用此代碼:

try { 
      filterChain.doFilter(servletRequest, servletResponse); 
     } 
     catch (Throwable e) { 
      e.printStackTrace(); 
      System.out.println("Stack trace:"); 
      System.out.println(e.getStackTrace()); 
      System.out.println("Cause:"); 
      System.out.println(e.getCause()); 
     } 

但沒有捕捉任何東西,堆棧跟蹤中的第18行是這一個:

filterChain.doFilter(servletRequest, servletResponse); 

沒有任何東西被try塊捕獲。

有人有什麼想法我怎麼能接近真正的原因?

BTW:JSF不是視圖技術。 JSP或Facelets都是。 JSF是一個MVC框架。 – BalusC 2010-04-01 13:47:01

thanx BalusC,我做了更正 – Michal 2010-04-10 05:03:26

好吧,我已經改變了我的過濾器和我的過濾器映射在web.xml中的順序,現在我的過濾器捕捉到了真正的異常。

他們的順序是什麼,他們現在的順序是什麼?我遇到了同樣的錯誤,並且捕獲真正的異常會有很大幫助。謝謝! – Pithlit 2012-02-29 16:44:57
