我已经完成了在新环境中设置MySql所需的一切，我总是成功地将它转移到另一台PC。但现在有一个错误，该错误表示：通过JSP连接到MySql时出错

HTTP Status 500 - An exception occurred processing JSP page /include/database.jsp at line 4

你有更多的堆栈跟踪共享？ –

您需要到MySQL连接器jar添加到类路径的Web应用程序，所以可能只是罐子复制到WEB-INF/lib文件夹。

我试着重新创建一些页面，并为缺少的jar获得了500个 - 之后 - 连接可用，但是我没有真正运行语句，因为你的问题从来没有那么远。
