程序如下：
<%@ page contentType="text/html;charset=gb2312"%>
<%@ page import="java.sql.*"%>
<html>
<body>
<%
try{
Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
}
catch(Exception e)
{
e.printStackTrace();
}
String url="jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=new";
String user="sa";
String password="sa";
Connection conn= DriverManager.getConnection(url,user,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql="select * from STUDENT_INFO";
ResultSet rs=stmt.executeQuery(sql);
while(rs.next()) {%>
您的第一个字段内容为：<%=rs.getString(1)%>
您的第二个字段内容为：<%=rs.getString(2)%>
<%}%>
<%out.print("数据库操作成功，恭喜你");%>
<%rs.close();
stmt.close();
conn.close();
%>
</body>
</html>
产生的错误如下：
javax.servlet.ServletException: No suitable driver
at org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:498)
at org.apache.jsp.MyJsp_jsp._jspService(MyJsp_jsp.java:77)

at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:198)
at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain
。。。。。。。。。。。。。。
请问为什么提示没有合适的驱动程序，该怎样改写？？？
说明：用纯java写的程序就可以顺利连接数据库没有以上错误！
