dspace錯誤空白xmlui頁面

Question

我在我的Ubuntu 16.04計算機上從源代碼安裝了dspace。我也跟着在長說明這裏的步驟：

https://wiki.duraspace.org/display/DSDOC6x/Installing+DSpace

當我嘗試訪問XMLUI頁面，我得到在瀏覽器中的白色屏幕和錯誤消息的日誌在一個長長的清單，以下。我已經檢查過，並且在src目錄中，Context.java具有方法getCurrentMode，該方法在150行上由CommunityBrowser.java調用。當我轉到jspui時，獲得了一個不錯的頁面，但是當我登錄時出現了相同的錯誤儘管它在頁面上顯示一條錯誤消息，而不是像xmlui一樣。

任何人都可以提出一些建議嗎？

和許多繭錯誤...

Answer 1

本來的第1天，我在安裝過程中做了幾個錯誤。例如，我第一次在dspace.cfg或local.cfg中未能設置數據庫密碼。我設置了密碼，然後再次嘗試而不刪除所有內容。我認爲它會覆蓋並糾正任何錯誤的東西。

所以在@Jens的建議之後，我認爲試圖找到衝突的jar文件對於使用與dspace一樣多的jar文件的安裝將非常困難。所以我從頭開始嘗試第二天。我下載了一個新文件，我從文件系統中刪除了我的數據庫和所有的dspace文件。我開始了，並從錯誤中吸取了教訓，經歷了安裝步驟，沒有出現錯誤，最後一切都奏效了。我現在有一個我可以修改的源代碼安裝。

再次感謝@Jens的指針。
