無法找到或提供資源

我正在Glassfish 4服務器上使用Java EE 6和Primefaces進行Web應用程序。我越來越頻繁地收到同樣惱人的錯誤。我試圖谷歌這個問題，但我還沒有找到一個可行的解決方案。有時候，應用程序的執行完全沒有問題，但是突然間一次又一次地發生了同樣的錯誤。這是我的堆棧跟蹤：無法找到或提供資源

同樣的錯誤會發生幾次，但後來暫時無法服務資源，如：jQuery的/ jQuery的plugins.js，佈局/ layout.js，jQuery的/的jquery.js， primefaces.js。全部來自Primefaces庫。

這個錯誤一直困擾着我很長一段時間，並將不勝感激！

請注意客戶端從服務器獲取資源作爲HTTP GET請求。這意味着對於每個CSS，JS或HTML文件，您都會收到一個HTTP請求。

打開你瀏覽器的網頁控制檯，然後點擊網絡。然後去任何網站，你會看到你有多少要求。

以下是關於您的問題的一些建議。

儘量增加你的服務器的最大池大小。在這裏閱讀http://docs.oracle.com/cd/E26576_01/doc.312/e24936/tuning-glassfish.htm#abeea - >調整EJB池設置
嘗試分析您的Web應用程序，並查看是否有太多請求使用相同的資源。如上所述，您可以在瀏覽器中執行此操作。
分析你無用進口的JSP，包括或iFrame

我希望這有助於

謝謝您的快速答覆！ – user2614556

到目前爲止，我似乎解決了我的問題。我從我的庫中刪除了Primefaces 3.5.jar，並將其替換爲Primefaces 3.4.2.jar，現在一切似乎都奏效......其他人有沒有Primefaces 3.5的問題？ – user2614556
