I'm new in J2ME. I have been strugling with this problem for weeks now. All I find on the net is some theory and is not helping me much. Here the deal
I have created a Midlet that shoud display a certain list which is from the remote database. The list comes from a JSP file in the server. When I use the browser I can see the list.
The problem comes when I have to take the same list and output it in my midlet file. Then finding the selected index of the selecte item of the same list and using it somewhere else.
I would appreciate it if somone could help me !!
My head is speaning now !!! If you want me to post my code so one could identidy the proble, I don't mind !! Help please !!

   // Custom declaration code starts here
   public CreateAppointment_GUI()
            //Creating a login Form
            loginScreen = new Form("Login");
            //Login form Textfields
            username = new TextField("Username:", null, 200, TextField.ANY);
            password = new TextField("Password:", "Initial text", 200, TextField.ANY|     TextField.PASSWORD);
            loginScreen.append(username);

}That is my midlet !! Now here is the code for my JSP !!
                    <%@ page import="java.sql.*" %>
<%@page import="java.util.*,java.text.*" %>
<%
String name="";
String id = "";
String connectionURL = "jdbc:microsoft:sqlserver://10.2.25.223;DatabaseName=NDOH_PAAB";
Connection connection = null;
Statement statement = null;
ResultSet rs = null;
%>
<%
try
                        Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver").newInstance();
                catch (Exception ex)
                        out.println(ex.toString());
                        connection = DriverManager.getConnection(connectionURL,"remotepaab_user","mohwiti2004");
                        statement = connection.createStatement();
                        String mysql ="SELECT * from physicians";
                        //out.println(mysql);
                        rs = statement.executeQuery(mysql);
%>
<%
      while (rs.next()) {
             name= rs.getString("name");
             id = rs.getString("id");
             out.print(name + "%");
             out.print(id + "%");
%>
<%
%>
<% rs.close(); %>In the JSP the name variable is the one that has my List. The problem is how do I say in my Midlet = display the list contained in name. Or in id. I need to use both of them "name + id". the id I will use to find out which name a user ha selected !! Not sure how !!!
Any help would be appreciated !! Thanks !!
