Answer 1

What you want to do is first define an object to represent the information from getAccounts() - something like AccountBean.

Then in your servlets doPost or doGet function, use the request info to populate your AccountBean object.

You can then store the AccountBean object either in the request, session, or servlet context by using the setAttribute method, and forward the request to the JSP page.

The AccountBean data in your jsp page is extracted using the and tags.

Here might be an example of your servlet:

protected void doPost(HttpServletRequest req, HttpServletResponse resp) {

  // get data from request querystring
  String accountId = req.getParameter("accountid");

  // populate your object with it (you might want to check it's not null)
  AccountBean accountBean = new AccountBean(accountId);

  // store data in session
  HttpSession session = req.getSession();
  session.setAttribute("accountBean", accountBean);

  // forward the request (not redirect)
  RequestDispatcher dispatcher = req.getRequestDispatcher("account.jsp");
  dispatcher.forward(req, resp);
}
