How can I save all the data from different textboxs in an array, using JSTL?

I want to recieve any number of textbox values, and save it to an array with JSTL if it's possible.
I generate all the texbox where numberAsked can be any number.
<c:if test="${param.buttonSend != null}">
<form action="index.jsp" method="post">
<c:forEach var = "i" begin = "1" end = "${param.numberAsked}">
<input type="text" name="textbox[]" class="form-control">
</c:forEach>
<button type="submit" name="buttonSave">Save</button>
</form>
</c:if>
Now I want to save all the textboxs in an array.
<c:if test="${param.buttonSave != null}">
<c:set var="data" value="${request.getParameterValues(textbox)}"/>
<c:forEach var = "item" items="${param.data}">
<c:out value="${item}"/>
</c:forEach>
</c:if>
But, it doesn't work, how can I save all the data from all the generated textboxs in an array?.

Here is a demonstration JSP.
<%# taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<form method="post">
<c:forEach var = "i" begin = "0" end = "5">
<input type="text" name="textbox">
</c:forEach>
<button type="submit" name="buttonSave">Save</button>
</form>
<c:set var="data" value="${paramValues.textbox}"/>
<c:forEach var = "item" items="${data}">
${item}
</c:forEach>

Sending data using <a href="#"> in the same page and display the result (FORM) using JSP without changing the (FORM) coding

<div id="main_search">
<table>
<tr>
<td>Product</td>
<td>:</td>

<input type="checkbox" name="product" class="prod_checkbx" value="Bilateral-VC">Bilateral-VC
<br>
<input type="checkbox" name="product" class="prod_checkbx" value="Bilateral Non-VC">Bilateral Non-VC
<br>
<input type="checkbox" name="product" class="prod_checkbx" value="Budget Domestic">Budget Domestic
<br>
<input type="checkbox" name="product" class="prod_checkbx" value="Budget High">Budget High
<br>
<input type="checkbox" name="product" class="prod_checkbx" value="Budget International">Budget International
<br>

</sql:query>
<c:forEach var="row" items="${dest_result.rows}">

<c:forEach var="row" items="${prod_result.rows}">

This is some kind of form without <form> tag and for submit button it didn't use <input type="submit"> like normal form. It use <a href="#"> to submit the data.
The question is how do you send the data using the <a href="#">???
In addition, when i click the SEARCH button both <% String dest = request.getParameter("destination"); %> and <% String products[]= request.getParameterValues("product"); %> didn't received any data.
When using the standard form, both can display result. This code is written in same page(JSP).
--The first coding cannot be changed because it was the assignment and need to solve it.--

Add a form tag in your code like
<form name="form1" method="POST">
<table>
<!-- Your code ->
<a id="search" name="search" class="button orange small" style="cursor:pointer" href="javascript:void(0);" onclick="document.form1.submit();">SEARCH</a>
</table>
</form>
Things to remember
Form tag: method(POST), Name of form(form1)
Method called on onclick of a tag

Link to the correct item page by selecting the list of items in for loop

This is my jsp page that retrieve the list of items from database using for loop
<%
itemManager mgr = new itemManager();
Item[] items = mgr.getAllItems();
for(int i = 0; i < items.length; i++){
%>
<tr>
<td> <img border="0" src="<%=items[i].getItemImage() %>" width="100" height="100">
</td>
<td>
<%=items[i].getItemName()%>
<input type="text" name="itemID" value="<%=items[i].getItemID()%>">
<br/>
<%=items[i].getItemDesc()%>
<br/>
Start Bid : <%=items[i].getStartBid()%>
<br/>
Buy it now : <%=items[i].getEndBid()%>
<br/>
Bidding close on : <%=items[i].getDuration()%>
<br/>
<input type="submit" value="View">
<%
}
%></table>
This is the jsp page that link to the item you selected previously
<table border="1" align="center">
<%
itemManager mgr = new itemManager();
Item items = mgr.getItem((Integer)session.getAttribute("ITEM_DATA"));
%>
<tr>
<td> <b> <%=items.getItemName() %></b> </td>
</tr>
</table>
This is the servlet to store the session of the selected item id and forward to the correct item jsp page.
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
HttpSession session = request.getSession(true);
int id = Integer.parseInt(request.getParameter("itemID"));
session.setAttribute("ITEM_DATA",id);
RequestDispatcher rd = request.getRequestDispatcher("viewItem.jsp");
rd.forward(request, response);
}
However, after I clicked the view button. It keeps linking to the itemID = 1.
The URL dispalys "/ItemServlet?itemID=1&itemID=2" .
In fact, if I click on itemID=2 the URL should display like this:
"/ItemServlet?itemID=2"
As a result, how can I achieve this? Thanks in advance!

The problem in your code is you are using a single form and dynamically creating Input box inside the form. So all the input box will be having same name. That's why when you submit the form all the input box values are sent as request parameters. I just reduced some part in your code for better under standing. Take this as your code
<form action="item" method="get">
<table>
<%
ItemManager mgr = new ItemManager();
Item[] items = mgr.getAllItems();
for(int i = 0; i < items.length; i++){
%>
<tr>
<td>
<%=items[i].getItemName()%>
<input type="text" name="itemID" value="<%=items[i].getItemId()%>">
<input type="submit" value="View"> </td></tr>
<%
}
%></table>
</form>
When you run this code and if you check the rendered HTML code it will be look
<form action="item" method="get">
<table>
<tr><td>
aaa
<input type="text" name="itemID" value="1">
<input type="submit" value="View"> </td></tr>
<tr>
<td>
bbb
<input type="text" name="itemID" value="2">
<input type="submit" value="View"> </td></tr>
<tr><td>
ccc
<input type="text" name="itemID" value="3">
<input type="submit" value="View"> </td></tr>
</table>
</form>
Here All the Input box having same name as "itemID". As a solution you can create the form inside the for loop, so that while submitting only one Input box value will be sent as request.
Create form inside your for loop like below code.
<table>
<%
ItemManager mgr = new ItemManager();
Item[] items = mgr.getAllItems();
for(int i = 0; i < items.length; i++){
%>
<form action="item" method="get">
<tr>
<td>
<%=items[i].getItemName()%>
<input type="text" name="itemID" value="<%=items[i].getItemId()%>">
<input type="submit" value="View"> </td></tr>
</form>
<%
}
%></table>
Hope This will help you.

change the name of text field dynamically.
And use getQueryString() in servlet to find the itemId name and value. by using EL.I hope this will help you

How can I solve this issue??????
Please guide me.

<aui:select showEmptyOption="true" name="select hospital name" required="true">
</aui:select>
THis may help you.

just assign an id to the aui:select tag
<aui:select inlineField="true" label="xxx" name="xxx" id="xxxId">
and then you can get the value with this (javascript + AUI)
var selectedVal = A.one('#<portlet:namespace/>xxxId').val();
with the selected value you can perform any kind of validation.

Convert Scriplet Array to JSTL Array

Hello I'm trying to change this bit of code into JSTL. I'm using scriptlets here.
<div id="slider">
<form action="gamepage" method="post">
<div class="sliderclass" id="slider1">
<% SiteDatabase database = new SiteDatabase();
Game game =(Game) database.getGames();%>
<% String[] newgames = game.getNewGames();
String[] imgSrc = {"images/spidermancover.jpg","images/blackopscover.jpg", "images/laststorycover.jpg", "images/ncaa13cover.jpg"
,"images/uncharted3cover.jpg", "images/mariokart7cover.jpg"};%>
<%for(int i =0; i < 6; i++) {%>
<div class="contentwrapper">
<button type="submit" style="border: 0; background: transparent" name="game" VALUE="<%=i%>"><img src="<%=imgSrc[i]%>" name="what"/></button><div id="slidertext"><%= newgames[i] %></div></div>
<%}%>
</div>
</form>
</div>
to something like this
<div class="slider">
<div id="slider1" class="sliderclass">
<jsp:useBean id="games" class="services.SiteDatabase" scope="request">
<jsp:SetProperty property="gameTitle" name="games" value="gameTitle"/>
</jsp:useBean>
<jsp:useBean id="game" class="services.Game" scope="request">
</jsp:useBean>
<c:set var="gameTitle" scope="request" value="game"/>
<c:set var="gameSrc" scope="request"><jsp:getProperty property="gameSrc" name="game"/></c:set>
<c:set var="gameId" scope="request"><jsp:getProperty property="gameId" name="game"/></c:set>
<c:forEach var="i" begin="0" end="6">
<div id="contentwrapper">
<img src="" name="what" />
<div id="slidertext"><jsp:getProperty property="gameTitle" name="gameTitle" /></div>
</div>
</c:forEach>
</div>
</div>
The scriplet works fine, i just want to meet standards and use JSTL

You can iterate array/list via JSTL <c:forEach/>.
<c:forEach var="img" items="images/spidermancover.jpg","images/blackopscover.jpg",
"images/laststorycover.jpg", "images/ncaa13cover.jpg",
"images/uncharted3cover.jpg","images/mariokart7cover.jpg">
<p>
${img}
</p>
</c:forEach>
Or
<c:forEach var="game" items="${games.newGames}">
<p>
${game}
</p>
</c:forEach>
