Openfire的錯誤，沒有答案

Question

我運行的Openfire服務器作爲我的聊天服務器的基礎，但我不喜的Openfire的魯棒性，它似乎有很多java的錯誤，

Java專家的人我談到誰說它的所有編碼錯誤，即Java異常沒有正確處理。只是想從Java專家知道的是下面的錯誤真的是java編程問題還是我的服務器或設置問題。

Answer 1

這可以是一個與你（或沒有）傳遞到你的數據庫驅動程序的參數問題 - 或者可能在數據庫驅動程序本身的錯誤。我的猜測是，你沒有在你的數據庫連接字符串中傳遞所需的屬性。

這當然不是用的Openfire本身就是一個問題 - 我們已經使用了很多年的Openfire現在，這是一個特殊的軟件。
