Paging with JSTL

Question

Hi everyone. I'm new at the forum, a begginer programmer and I'm apologize for my english cuz is not very good ;). I'm making a project using only JSTL, I can't use the JSP embedded code, only JSTL, and a postgreSQL DB. Writing the paging I made the next code using only the JSTL and submit buttons which works very good.
<form action="/Paginaciones03/Consultas" method="POST">
            <table>
                <tr>
                    <input type="hidden" value="${limite}"/>
                    <%--Three first pages case--%>
                    <c:if test="${offset == 1}">
                        <td><b><c:out value="${offset}" /></b></td>
                        <c:if test="${paginas >= 2}">
                            <td><input type="submit" name="offset" value="${offset + 1}" class="sbmt"></td>
                        </c:if>
                        <c:if test="${paginas >= 3}">
                            <td><input type="submit" name="offset" value="${offset + 2}" class="sbmt"></td>
                        </c:if>
                        <c:if test="${paginas >= 4}">
                            <td><input type="submit" name="offset" value="${offset + 3}" class="sbmt"></td>
                        </c:if>
                        <c:if test="${paginas >= 5}">
                            <td><input type="submit" name="offset" value="${offset + 4}" class="sbmt"></td>
                        </c:if>
                        <c:if test="${paginas >= 6}">
                            <td><input type="submit" name="offset" value="${offset + 5}" class="sbmt"></td>
                        </c:if>
                        <c:if test="${paginas >= 7}">
                            <td><input type="submit" name="offset" value="${offset + 6}" class="sbmt"></td>
                        </c:if>
                        <c:if test="${paginas > 3 && offset < paginas}">
                            <td>Ultima:<input type="submit" name="offset" value="${paginas}" class="sbmt"></td>
                        </c:if>
                    </c:if>

                    <%--Remainin pages--%>
                    <c:if test="${offset >= 2}">
                        <c:if test="${offset - 3 > 0 }">
                            <td><input type="submit" name="offset" value="${offset - 3}" class="sbmt"></td>
                        </c:if>
                        <c:if test="${offset - 2 > 0 && offset - 3 == 0}">
                            <td><input type="submit" name="offset" value="${offset - 2}" class="sbmt"></td>
                        </c:if>
                        <c:if test="${offset - 2 > 1 }">
                            <td><input type="submit" name="offset" value="${offset - 2}" class="sbmt"></td>
                        </c:if>
                        <td><input type="submit" name="offset" value="${offset - 1}" class="sbmt"></td>
                        <td><b><c:out value="${offset}" /></b></td>
                        <c:if test="${offset + 1 <= paginas}">
                            <td><input type="submit" name="offset" value="${offset + 1}" class="sbmt"></td>
                        </c:if>
                        <c:if test="${offset + 2 <= paginas}">
                            <td><input type="submit" name="offset" value="${offset + 2}" class="sbmt"></td>
                        </c:if>
                        <c:if test="${offset + 3 <= paginas}">
                            <td><input type="submit" name="offset" value="${offset + 3}" class="sbmt"></td>
                        </c:if>
                        <c:if test="${paginas > 3 && offset < paginas}">
                            <td>Ultima:<input type="submit" name="offset" value="${paginas}" class="sbmt"></td>
                        </c:if>
                    </c:if>
                </tr>
                <tr>
                    <td><br/></td>
                </tr>
                <tr><td>
                        Resultados por p&aacute;gina: <select name="limite">
                            <option value="10">10</option>
                            <option value="20">20</option>
                            <option value="50">50</option>
                        </select>
                    </td>
                </tr>
                <tr><td>Mostrando: ${limite}</td>
                </tr>
            </table>
        </form>The question now is how I can reload the page with the select, using JSTL, and remains the limit number. Thank you very much. If you ask me, I can post the servlet.
