jdbc连接sql server数据库问题,大家帮我看一下这段代码

public class DBConnection 
{
private Connection con;

public Connection getConnection()
{
try
{
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
String url = "jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=UserTest";
String user = "sa";
String pwd = "sa";
this.con = DriverManager.getConnection(url, user, pwd);
}
catch (ClassNotFoundException exc0)
{
exc0.printStackTrace();
}
catch (InstantiationException exc1)
{
exc1.printStackTrace();
}
catch (SQLException exc2) 
{
exc2.printStackTrace();
}
catch (IllegalAccessException exc3)
{
exc3.printStackTrace();
}
return this.con;
}
}那三个jar文件我已拷到Web-INF\lib下,怎么老是得不到Connection对象,老是引发SQLException,我的开发环境是window xp(sp2) + eclipse + myeclipse + tomcat5.0

  2.   

    是this.con = DriverManager.getConnection(url, user, pwd);这句引发的异常SQLException
      

  3.   

    SqlServer 数据库的补丁,到网上下一个
      

  4.   

    对，是SQl Server补丁的问题，你下SP3的补丁，装上，试试，我好是刚知道的
      

  5.   

    sqlserver打补丁，sp3以上才支持JDBC
