我有WL 6.1 Studio（頂級RAD 9.0.1）+ WAS Liberty Profile 8.5.5.1 + WL 6.1 + Derby DB。Worklight 6.1日誌中的JPA錯誤：無法啓動應用程序
在某個時間點，我開始接收錯誤，我的WL應用程序無法啓動，從WAS日誌似乎JPA（或JPA類加載衝突）的問題？
我可以檢查什麼來解決它？
下面是從日誌文件中的相關片段（應用程序無法啓動）

當您的項目開始發生時，您發生了什麼變化？嘗試1）關閉Eclipse，2）刪除您的工作區\ WorklightServerConfig文件夾。它將在下次啓動Eclipse時重新創建。 –
一些額外的信息：1）我正在使用獨立的WAS Liberty Profile，未與WL Studio捆綁在一起（需要一些不包含在捆綁Liberty中的功能）2）什麼*可能*會破壞它（不知道它有多真實）另一個（不是WL）Web應用程序，它使用Spring 4.0 Web MVC。 –
如果你刪除該安裝？ –
