我把驱动包（4个，包括jtds包）已经放到lib目录下了，我用jtds就可以连上
<%@ page contentType= "text/html; charset=gb2312 " language= "java " import= "java.sql.*,java.io.* " errorPage= " "%>
<%
Class.forName( "net.sourceforge.jtds.jdbc.Driver ");
//String url = "jdbc:jtds:sqlserver://localhost:1433/mydb ";
String url=
"jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=mydb ";
Connection con = java.sql.DriverManager.getConnection(url, "sa ", " ");
PreparedStatement pstmt = con.prepareStatement( "select * from course ");
ResultSet rs = pstmt.executeQuery();
out.println( " <table> ");
while(rs.next())
{
out.println( " <tr> ");
out.println( " <td> "+rs.getString(1)+ " </td> ");
out.println( " <td> "+rs.getString(2)+ " </td> ");
out.println( " <td> "+rs.getString(3)+ " </td> ");
out.println( " <td> "+rs.getString(4)+ " </td> ");
out.println( " <td> "+rs.getString(5)+ " </td> ");
out.println( " </tr> ");
}
out.println( " </table> ");
