我有这样的代码:
try
{
Class.forName("net.sourceforge.jtds.jdbc.Driver");
Connection conn = DriverManager.getConnection(
"jdbc:jtds:sqlserver://myMachine:1433/myDB;instance=sql2008;user=myUserName;password=myPassword;"
);
System.out.println("connected");
}
catch (Exception e)
{
e.printStackTrace();
}
这是我得到的例外:

在Sql配置管理器我已经设置TCP/IP，命名管道，共享内存和VIA设置为启用。
我已经验证了提供的用户名和密码是正确的。并且端口号是正确的。
为什么我得到这个错误，如何解决这个问题?
PS:我正在使用sql server 2008 express我知道了。SQL Service browser服务未启动。在我启动这个服务之后，我可以连接到服务器。
