我经历了几次尝试不同版本的 JTDS 驱动程序的迭代，但都没有成功。我切换到 Microsoft jar 并终于取得了一些成功。
**** jtds driver config ****
# Database configuration for M$ SqlServer <currently not working...jtds>
# db.default.url="jdbc:jtds:sqlserver://
an_ip_addy_to_a_server:1433/db_instance;user=user_name;password=user_password"
# db.default.driver=net.sourceforge.jtds.jdbc.Driver
**** M$ driver config ****
# Database configuration for M$ SqlServer <WORKING!!!..m$ driver>
db.default.url="jdbc:sqlserver://
an_ip_addy_to_a_server\db_instance:1433;user=user_name;password=user_password"
db.default.driver=com.microsoft.sqlserver.jdbc.SQLServerDriver
差异？？
1) sqljdbc4.jar 是一个“非托管依赖项”：http ://www.playframework.com/documentation/2.1.0/SBTDependencies 2) 根据我阅读的每个文档，URL 字符串明显不同。
至少我现在可以开始取得一些进展。

我是 Scala 语言和堆栈的新手，我希望这是一个很容易解决的问题。
设置：
- Play2（斯卡拉）
- 光滑的 1.0.0
- SQL Server 2008
- JTDS 1.3.0
每当我启动应用程序并点击初始页面 localhost:9000 时，似乎框架正在尝试获取与数据库的连接，但它抛出了一个异常：
有什么想法吗？
