JSP连接数据库问题?先谢谢各位!!!
代码部分

Java code

Connection conn = null;
 String driver = "com.microsoft.jdbc.sqlserver.SQLServerDriver";
 //String driver = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
 String url = "jdbc:microsoft:sqlserver://168.57.5.10:1433;DatabaseName=NetBank";
 String name = "sa";
 String pass = "123456";
//连接数据库的方法
try
{
System.out.println("***加载数据库驱动***");
Class.forName(driver);
System.out.println("***数据库驱动加载成功***");
System.out.println("***连接数据库***");
conn = DriverManager.getConnection(url, name, pass);
System.out.println("***数据库连接成功***");

} catch (ClassNotFoundException ce)
{
System.out.println("找不到jar驱动包或者驱动连接字符出错!");
ce.printStackTrace();
} catch (SQLException se)
{
System.out.println("SQL连接字符串出错!");
se.printStackTrace();
} catch (Exception e)
{
e.printStackTrace();
}

提示的错误:
***加载数据库驱动***
***数据库驱动加载成功***
***连接数据库***
SQL连接字符串出错!
