错误连接到SQL Server数据库

Question

当我尝试用下面的代码连接到我的数据库：

try 
{ 
    String connectionUrl = "jdbc:sqlserver://192.168.0.78;instanceName=SQL2014;databaseName=GIDS;user=sa;password=invent"; 
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
    Connection con = DriverManager.getConnection(connectionUrl); 
    System.out.println("Database connection = "+con); 
} 
catch(Exception e) 
{ 
    e.printStackTrace(); 
    System.out.println("Error connecting to database. Error: "+e.getMessage()); 
} 

我得到以下异常：

Error: com.microsoft.sqlserver.jdbc.SQLServerDriver

我在做什么错？
