Please help in List.MULTIPLE

Question

Hi,
I wish to know how do I append datas dynamically using jsp into a list. a multiple list. ? Is it possible? I have a jsp page with connection to my mysql server which I call using the httpconnection and I would like to append each data eg: option 1, option2, option3....
I manage to put into string and append it into a textbox but how to go about appending it to a multiple list? Is it possible.
Please advice as I am very desperate. Thanks in advance. ( see codes below)

connectmidlet.jsp
<%@ page language="java" import="java.sql.*" %>
<%!
String name;
String Shows;
String Time;
String conn;
%>
<%
name = request.getParameter("name");
out.println("Hello "+name+",");
Class.forName("org.gjt.mm.mysql.Driver");
conn = "jdbc:mysql://localhost:3306/fyp?user=root&password=";
Connection Conn = DriverManager.getConnection(conn);
// query statement
Statement SQLStatement = Conn.createStatement();
// generate query
String Query = " SELECT *  FROM schedules ";
// get result
ResultSet SQLResult = SQLStatement.executeQuery(Query);
             while(SQLResult.next())
                        Shows = SQLResult.getString("shows");                         
                       Time = SQLResult.getString("times");
                        out.println("Show : "+Shows+ "\n"+ "Time : " + Time+"\n");
// close connection
SQLResult.close();
SQLStatement.close();
Conn.close();

Well, you already have all the string in a StringBuffer (you called it "b"). So you set up a start variable (initially 0), you get the indexOf('\n'), and add that substring to an array (or a Vector if you don't know how many elements to expect), then set start to be the character after '\n', and keep it up until you reach the end of the string.
