希望大家能为我提供帮助，在我身旁使用MuleSoft（MS）专家已有2天了，我们不能解决这个问题。简而言之，我们无法连接到SQL
Server数据库。我正在使用Generic_Database_Connectory以下信息：

• 网址： jdbc:jtds:sqlserver://ba-crmdb01.ove.local:60520;Instance=CRM;user=rcapilli...
• 驱动程序类名称： com.microsoft.sqlserver.jdbc.SQLServerDriver

这是一个sqljdbc4.jar文件，最新的。“测试连接”工作正常。那里没有问题。但是当我运行该应用程序时，出现此错误（如下）

任何人都可以使SQL Server数据库连接正常工作？？？
