Pass variables and return ResultSet from same preparedStatement

Question

I am passing "fp" and "week_no" to a preparedStament in a class and want to return the values to my jsp page. "fp" and "week_no" are used twice. Please see below. When I run it, I get no error messages but, it doesn't display any data.
I have the following code in a class:
public ResultSet getHistory(String fp, String week_no)
                    throws SQLException, Exception {
ResultSet rs = null;
if (con != null) {
try {
     PreparedStatement getHist;
     getHist = con.prepareStatement(
     "SELECT sbu, TO_CHAR(((sum_dollar) + (adj_sum_dollar)),'$999,999,999.99') AS sum_dollar, TO_CHAR(actual_date,'MM/DD/YY') AS actual_date, " +
     "((sum_cases) + (adj_sum_cases)) AS sum_cases, " +
     "((new_order_cases) + (adj_new_order_cases)) AS new_order_cases, " +
     "((total_open_orders) + (adj_total_open_orders)) AS total_open_orders, " +
     "((back_orders) + (adj_back_orders)) AS back_orders, " +
     "TO_CHAR((sum_dollar/sum_cases), '999.99') AS yield " +
     "FROM SUMMARY " +
     "WHERE actual_date BETWEEN (SELECT begin_dt " +
               "FROM fiscal_calendar " +
                         "WHERE fiscal_period = '?' " +
                         "AND week_number = '?' " +
                         "AND week_number <> '9' " +
                         "AND fiscal_yr = '2003') " +
                    "AND " +
                         "(SELECT end_dt " +
                    "FROM fiscal_calendar " +
                         "WHERE fiscal_period = '?' " +
                         "AND week_number = '?' " +
                         "AND week_number <> '9' " +
                         "AND fiscal_yr = '2003') " +
          "ORDER BY actual_date, sbu ");
     getHist.setString(1, fp);
     getHist.setString(2, week_no);
     getHist.setString(3, fp);
     getHist.setString(4, week_no);
     rs = getHist.executeQuery();
     } catch (SQLException sqle) {
error = "SQLException: Update failed, possible duplicate entry.";
     throw new SQLException(error);
} else {
error = "Exception: Connection to the database was lost.";
     throw new Exception(error);
return rs;
This is in my jsp:
<%
String fp = request.getParameter("fp");
String week_no = request.getParameter("week_no");
historyInfo.connect();
ResultSet rs = historyInfo.getHistory(fp, week_no);
while (rs.next()) {
//String sum_dollar = rs.getString("sum_dollar");
%>
<%= rs.getString("sum_dollar") %>
<%
%>

Hi,
First thing U can't do this way in java. If U are executing this sort of database query, after retriving all the values, put inside Haahtable or HashMap as the application required and return it.
Otherwise execute this query at the same place where u r printing values in jsp page insted of writing it inside seperate method..It will work.
If still it's not workimg, please let me know.
