Openfire的错误，没有答案

Question

我运行的Openfire服务器作为我的聊天服务器的基础，但我不喜的Openfire的鲁棒性，它似乎有很多java的错误，

Java专家的人我谈到谁说它的所有编码错误，即Java异常没有正确处理。只是想从Java专家知道的是下面的错误真的是java编程问题还是我的服务器或设置问题。

Answer 1

这可以是一个与你（或没有）传递到你的数据库驱动程序的参数问题 - 或者可能在数据库驱动程序本身的错误。我的猜测是，你没有在你的数据库连接字符串中传递所需的属性。

这当然不是用的Openfire本身就是一个问题 - 我们已经使用了很多年的Openfire现在，这是一个特殊的软件。
