WebSphere 8共享庫白屏錯誤

Question

在WebSphere 8中，我向已安裝的Java EE應用程序添加了共享庫並單擊了「Ok」， 我總是使用白色屏幕而不是普通的WebSphere工作流程（WebSphere 8應該將共享庫連接到應用程序，並詢問我是否要保存更改）。

服務器的SystemErr.log：

但是：

1. 添加共享庫在安裝過程（ 「Java EE應用程序的安裝」 過程的階段4）成功完成的部分。
2. 在WebSphere 7中，添加共享庫的兩種方式均可正常工作。

有什麼建議嗎？

Answer 1

那麼，我決定安裝8.5.x，在這個最新版本我的問題消失了。
