How to send object arraylist from servlet to jsp and display using jstl

Question

Hi All....
I have a simple application and problem with it.
Once user logged in to system the user will redirect to LoginServlet.java controller.
Then in LoginServlet I want to redirect user to another page called book_details.jsp.
this is my login servlet.
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
          // TODO Auto-generated method stub
          PrintWriter out = response.getWriter();
          ArrayList<BankAccountDTO> account_list = new ArrayList();
          ResultSet resultSet = null;
          LowFairAirDB airDB = null;
          try{
               airDB = new LowFairAirDB();
               String query = "SELECT account_id, type, description, balance, credit_line, begin_balance, begin_balance_time_stamp FROM bank_account";
               airDB.sqlSelect(query);
               resultSet = airDB.getResultSet();
               while(resultSet.next()){
                    account_list.add(new BankAccountDTO(resultSet.getInt(1),
                                                                 resultSet.getInt(4),
                                                                 resultSet.getInt(5),
                                                                 resultSet.getInt(6),
                                                                 resultSet.getString(2),
                                                                 resultSet.getString(3),
                                                                 resultSet.getString(7)));
          }catch(Exception ex){
          }finally{
               try{resultSet.close();}catch(Exception ex){}
               airDB.sqlClose();
     }I set bank account values to BankAccountDTO.java objects and add them to the arrayList.
Next I want to send this objects arrayList to books_details.jsp and wanna display each objects values using JSTL.
I still finding a way to go through this.
1. Can anyone say how can I do it?
2. Is there any other method to do the same thing without using JSTL?
thanks in advance,
Dil.

In your servlet,
request.setAttribute("account_list", account_list);
requestDispatcher.findForward("/your/display/jsp");
Good. I would only follow the Java naming conventions. E.g. accountList or accounts instead of the ugly PHP/C conventions.
In the JSP,
lst = (List< BankAccountDTO >)request.setAttribute("account_list");
for(BankAccountDTO b: lst){
populate your HTML tags or whatever
Wrong. 1) You need getAttribute() and 2) you should not use scriptlets. Use JSTL c:forEach, e.g.<table>
    <c:forEach items="${accounts}" var="account">
        <tr>
            <td>${account.id}</td>
            <td>${account.type}</td>
            <td>${account.description}</td>
        </tr>
    </c:forEach>
