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

How to pass variables defined in one jsp to another and then again after processing in another jsp include that jsp in first jap page

But the first page is never called by the user, an another page is called on whose button click the first jsp is called.So the values in the page which I included are never processed as it is never called.

One option is to use the session scope in order to have your variable available in any JSP or servlet during the current session.
You can store your variables in the session scope:
HttpSession session = request.getSession();
String variableToPass = "hello";
session.setAttribute("variableToPass", variableToPass);
And, you can access them like this:
HttpSession session = request.getSession();
String variablePassed = session.getAttribute("variableToPass");
Hope it is helpful.

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.

How to add values from checkbox to array?

I need your help.
I'm working on a jsp application.
The thing is that I have a form within a "select-option" then depending on the item I select from the "select option" I get a list with checkboxes, and I can get the checkboxes values in my servlet, but now what I try to do is to get does values and add them to an array. How can I do that?
JSP code:
//Select-option
<table>
<tr>
<td width="50%" style="text-align: left;">
<select class="selectSmall" id="a_selectCta" name="a_selectCta"
style="margin-bottom: 5px; width: 310px;">
<option value="">Seleccione un Cuentahabiente</option>
<%
for (Ctahabiente habiente : CtahabienteDAO.getCtahabientes()) {
if (ctahabiente != null && habiente.getIdCtahabiente().equalsIgnoreCase(ctahabiente.getIdCtahabiente())) {
%>
<option selected="selected" value="<%=ctahabiente.getIdCtahabiente()%>">
<%=ctahabiente.getIdCtahabiente() + " - " + ctahabiente.getDesCtahabiente()%></option>
<%
} else {
%>
<option value="<%=habiente.getIdCtahabiente()%>">
<%=habiente.getIdCtahabiente() + " - " + habiente.getDesCtahabiente()%></option>
<% } }
%>
</select>
</td>

How to make the jsp page not to show the previous value set in session?

Use HttpSession.removeAttribute(String name).
Removes the object bound with the specified name from this session. If
the session does not have an object bound with the specified name,
this method does nothing.
if (session.getAttribute("leaveMap") != null) {
reportMap = (Map<String,String>) session.getAttribute("leaveMap");
session.removeAttribute("leaveMap");
}

Put data it in request scope [request attribute], or override with blank map in Servlet when you make new request

If you are using session then each time after iteratig data you will have to remove that object from session. but if you are using request then you do not need to remove data from request. each time you will get a new request object and new data set as well.
