JSP菜鸟问连接SQL SERVER 2008的问题

Question

JSP代码
<%@ page contentType="text/html;charset=utf-8"%>
<%@ page import="java.sql.*"%>

<%

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver").newInstance();
String url="jdbc:sqlserver://localhost:1433;DatabaseName=DbTest";
String username="sa";
String password="123456";
Connection conn= DriverManager.getConnection(url,username,password);
Statement stmt=conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql="select * from Test";
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.println("数据库操作成功，恭喜你");%>
<%rs.close();
stmt.close();
conn.close();
%>

出现问题如下：

public Connection getConnection()
{
Connection conn=null;
//链接SQLServer2000

//String CLASSFORNAME="com.microsoft.jdbc.sqlserver.SQLServerDriver";

// String SERVANDDB="jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=tempdb";

//连接SQLServer2005
String CLASSFORNAME="com.microsoft.sqlserver.jdbc.SQLServerDriver";
String SERVANDDB="jdbc:sqlserver://localhost:1433;DatabaseName=jmorder";

// String SERVANDDB="jdbc:sqlserver://219.229.249.71;DatabaseName=jxpro_manage";
String USER="sa";
String PWD="123";
//String PWD="jxedu";

try
{
Class.forName(CLASSFORNAME);
conn=DriverManager.getConnection(SERVANDDB,USER,PWD);

}catch(Exception ex)
{
ex.printStackTrace();
