IBM Worklight 6.0 - 訪問Application Center管理控制檯時出現SAXException

Question

我目前正在嘗試讓Worklight Application Center在運行於WebSphere Application Server V8和WebSphere Portal v8上的Worklight v6的新安裝上運行。這看起來很簡單，IBM Installation Manager根本沒有抱怨。安裝完成後，我甚至可以登錄到應用程序中心。但是，該頁面顯示HTTP 500錯誤，並「灰顯」所有選項。這也可以防止再次註銷。

在WAS日誌，究竟會出現以下錯誤時的頁面出現了錯誤：

...我已經尋找這一切的錯誤，我能想到的組合，沒有解決方案，實際上似乎適用至今。觸發錯誤的jar「ilwwcm-eventlog-jpa.jar」似乎是Portal的庫存庫。爲了解決問題，我甚至試圖解壓庫存JAR，將引用的xml文件更改爲具有「1.0」而不是「2.0」，重新打包JAR，然後嘗試一下。這隻會導致WAS在同一個文件中的不同XML標籤上引發異常。

任何人看到這個，或有任何想法如何解決它？

Answer 1

我的猜測是Websphere爲您提供了錯誤版本的OpenJPA。應用程序中心自帶本地版本的OpenJPA。爲了消除來自全球OpenJPA的副作用，建議使用「家長最後的」類加載器策略：

輸入WebSphere Application Server管理控制檯：

• 在左側：應用程序>應用程序類型> Websphere企業應用程序
• 從企業應用程序列表中選擇應用程序中心（AppCenter或AppCenterServices）。
• 選擇「類加載和更新檢測」
• 類加載順序：加載本地類加載器第一類（父即止）

這通常不是默認的，但你應該使用這個。

• WAR類加載器的政策：在應用

類加載器爲每個WAR文件這應該是默認的，是良好的。

• 確認，如果出現關於更改的消息，請點擊「直接保存到主配置」。

可以肯定的是，之後重新啓動Websphere Application Server。

Answer 2

我有同樣的問題。 我想如果我刪除ilwwcm-eventlog-jpa.jar文件，它應該修復worklight。我將文件的擴展名從.jar改爲.abc，以使類加載器無法找到它。 這確實修復了WorkLight，但卻破壞了門戶的WCM創作Portlet。
