ok per il form, ma nel caso di un delete fatto da link?
codice:
        <c:forEach items="${requestScope.list}" var="lists">
            <tr>
                <td>
                    <c:out value="${lists.id}"/>
                </td>
                <td>
                    <c:out value="${lists.entrate}"/>
                </td>
                <td>
                    <c:out value="${lists.uscite}"/>
                </td>
                <td>
                    <c:out value="${lists.causale}"/>
                </td>
                <td>
                    <c:out value="${lists.data}"/>
                </td>
                <td>
                    Elimina
                </td>
            </tr>
        </c:forEach>
    </table>
servlet:
codice:
public class Delete extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        doPost(request, response);
    }

    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        Connection conn = null;
        PreparedStatement ps = null;
        String sql = "DELETE FROM movimenti WHERE id=?";
        int id = Integer.parseInt(request.getParameter("elimina"));
        try {
            conn = Connessione.getConnection();
            ps = conn.prepareStatement(sql);
            ps.setInt(1, id);
            ps.executeUpdate();
            RequestDispatcher disp = request.getRequestDispatcher("DoQuery");
            disp.forward(request, response);
        } catch (ClassNotFoundException ex) {
            ex.getMessage();
        } catch (SQLException ex) {
            ex.getMessage();
        } finally {
            try {
                ps.close();
            } catch (SQLException ex) {
                ex.getMessage();
            }
        }
    }
}
l'url diventa così:
http://localhost:8080/BancaJSP/Delete?elimina=28

è possibile ovviare qua in qualche modo??
