JSP how to Loop through an Array with Filters for unique objects?

Hi all I'm hitting a bit of a snag on this project I'm working on.
I'm trying to make a list of unique list of objects(properties) and give them a list of features you can select from a database table.
this is the code for populating that database
<% String selected_features = rz.fetch("real_estate", "selected_features");
%>
<input name="selected_features" type="hidden" value="<%=selected_features%>"/>
<rz:list module="estate_features" sort="seq_no asc" output="none" options="noscript" filter="">
<%
while(rz.listnext() && rz.listindex >= 0) {
%><rz:listbody>
<div class="rz-checkbox">
<%
String featureName = rz.fetch("estate_features", "feature_text");
String recordid = rz.fetch("estate_features", "_recordid");
String selected = "selected_features_box";
%>
<rzt:checkbox
label="<%=featureName%>"
field="<%=selected%>"
checkedValue="<%=rz.fetch("estate_features", "_recordid")%>"
target=""
checked="<%=("|"+selected_features+"|").indexOf("|"+recordid+"|") >= 0 ? "true" : "false"%>"
/>
<%=("|"+selected_features+"|").indexOf("|"+recordid+"|") >= 0 ? "true" : "false"%>
</div><!-- /.rz-checkbox -->
</rz:listbody>
<% } %>
</rz:list>
and this is the loop I've got going on the page
<rz:list module="real_estate" sort="seq_no asc" output="none" options="noscript" filter="<%="pageid=property-"+rz.pageid%>"><%
while(rz.listnext() && rz.listindex >= 0) {%><rz:listbody>
<%
String features = rz.fetch("real_estate", "selected_features");
String[] feature_arr = StringUtils.split(features, "|");
for (int i=0; i < feature_arr.length; i++ ) {
if(!feature_arr[i].equals("")){
String feature_name = rz.fetch("estate_features", "feature_text", "", "_recordid="+feature_arr[i]);
%>
<li>
<span><%=feature_name%></span>
</li>
<% } } %>
</rz:listbody>
<% } %>
</rz:list>
as of right now the feature works when I make a single unique object. But when I make a second object it generates the entire list
The numbers are the features variable and are the recordid from a test I'm doing the first set 42|43|44|45|46|47|48|49 are for the first object while 50|51|52|53|54|55 are for the second object

It's because your not setting a breakpoint for when it needs to end
for(int i=0; i < feature_arr.length; i++){
if(!feature_arr[i].equals("")){
String feature_name = rz.fetch("estate_features", "feature_text", "", "_recordid="+feature_arr[i]);
this is what you need--->if(feature_arr[i] === feature_name){

Spring MVC displaying arraylist in JSP correctly

i have a problem whith the displaying of an arraylist in jsp. it displays everything in one line for each person making repetition .
i have a table with columns (phone number,fax,phone2,email)
here is my dao function:
#Override
public ArrayList<String> moyenCom(Authentication auth) {
String login=auth.getName();
List list;
List listres = null;
ArrayList<String> array1=new ArrayList<String>();
//ArrayList<ArrayList<String>> array=new ArrayList<ArrayList<String>>();
SessionFactory factory=new Configuration().configure().buildSessionFactory();
Session session=factory.openSession();
session.beginTransaction();
//Your operation
String sql1="select r.id_responsable from WEBCARE.PERSONNE p,WEBCARE.RESPONSABLE r,WBB_CLU.ABONNE_COMPTE ac,WBB_CLU.COMPTE_CLU c where p.id=r.id_responsable and r.id_abonne=ac.id_abonne and c.id_compte=ac.id_compte and c.login=:x";
SQLQuery query1 = session.createSQLQuery(sql1);
query1.setParameter("x",login);
query1.setResultTransformer(Criteria.ALIAS_TO_ENTITY_MAP);
session.getTransaction().commit();
list=query1.list();
for(int i=0;i<list.size();i++){
String res =list.get(i).toString();
String[] parts = res.split("=");
String part2 = parts[1];
System.out.println("id du responsable est"+res);
System.out.println("id du responsable spliteeee est "+part2);
session.beginTransaction();
String sql="select mc.information from WEBCARE.MOYEN_COMMUNICATION mc,WEBCARE.PERSONNE p where p.id=mc.id_categorie and mc.id_categorie=:part2 and mc.categorie=1";
SQLQuery query = session.createSQLQuery(sql);
query.setParameter("part2",part2);
query.setResultTransformer(Criteria.ALIAS_TO_ENTITY_MAP);
session.getTransaction().commit();
listres=query.list();
for(int i1=0;i1<listres.size();i1++){
String resu =listres.get(i1).toString();
System.out.println("info "+resu);
array1.add(resu);
}
}
System.out.println(array1);
return array1;
}
my controller :
#RequestMapping("/fichets")
public String fichets(Model model,Authentication auth){
Authentication authen = SecurityContextHolder.getContext().getAuthentication();
String name = authen.getName(); //get logged in username
model.addAttribute("moycoms",metier.moyenCom(auth));
return "InfoAbonneTS";
}
and my jsp page :
<c:forEach items="${resps}" var="resp">
<tr>
<td id="date">${resp.nom} ${resp.prenom}</td>
<td>${resp.poste}</td>
<td>${resp.password}</td>
<c:forEach items="${moycoms}" var="moycom">
<td>${moycom}</td>
</c:forEach>
</tr>
</tbody>
</c:forEach>
The function returns the field information witch contains all the 4 informations that should be displayed each in every column.
arraylist returned is :
{information=01234567890}, {information=01999999999}, {information=0199999333}, {information=resp1#gmail.com}, {information=00 }, {information=0622355114}, {information=0588888888}, {information=respons3#gmail.com}, {information=00 }, {information=0111111111}, {information=0666666666}, {information=responsable4#gmail.com}
so the first four information should be displayed each in every column ,the second four same thing...in this example i have 3 persons.
i can't display this correctly any help?
resps is for displaying the first 3 columns

Looking at the data it looks like a List of Map. Try this code
<c:forEach items="${moycoms}" var="moycom" varStatus="stat">
<c:if test="${stat.index%4==0 && stat.index!=0}">
<tr>
</c:if>
<td>${moycom['information']}</td>
<c:if test="${stat.index%4==0 && stat.index!=0}">
</tr>
</c:if>
</c:forEach>
stat variable is used to find the current index. We are adding the <tr> based on the index so that its done for every fourth index. If resp contains some identifier which could be used for finding the correct user then use <c:if> for matching. Please provide additional information

you are adding only "moycoms" attribute to the model object
but you jstl starts from
<c:forEach items="${resps}" var="resp">
you are not adding any "resps" param in your model object

How to change list(select) data dynamically

I am adding product details.
So for that with it I have to add product attribute, product feature with it.
I am loading all data of attribute from mysql table.
I am using one mechanism that first user have to select attribute category from list (select control), when user select category then as per it data of other list (select control) changes.
main category image :
sub attribute category :
I have added data like this in JavaScript array :
var at_category_id = [];
var at_category_name = [];
<%
List<Integer> aIDList = (List<Integer>) request.getAttribute("aID");
List<String> aNAMEList = (List<String>) request.getAttribute("aNAME");
for (int i = 0; i < aIDList.size(); i++)
{
%>
at_category_id.push(<%= aIDList.get(i) %>);
at_category_name.push(<%= aNAMEList.get(i) %>);
<%
}
%>
var option_str = document.getElementById('list_main_category');
for (var i=0; i<at_category_id.length; i++)
{
option_str.options[option_str.length] = new Option(at_category_id[i],at_category_name[i]);
}
I have done same like this for attribute and add data to JavaScript array.
var at_id = [];
var at_name = [];
<%
List<Integer> acIDList = (List<Integer>) request.getAttribute("acID");
List<String> acNAMEList = (List<String>) request.getAttribute("acNAME");
for (int i = 0; i < aIDList.size(); i++)
{
%>
at_id.push(<%= acIDList.get(i) %>);
at_name.push(<%= acNAMEList.get(i) %>);
<%
}
%>
but now how to move forward I don't know.
I want to do something like that.
Means when user click on first list that is main category how second list will be changed ?
any suggestion please.

The usual way would be to put a javascript action on the value changing for the first combo box.
At that point you can either (easy way) submit the whole form and then send back the new page with the extra value added or (slightly more complex) do an AJAX call to fetch the data and populate the new dropdown.

JSTL Session Hash Map containing Objects - How to print Objects

I have a Servlet that gathers form data, makes a database query, retrieves the data, and puts it into a Hash Map. Such as below:
ResultSet rs = d.execute(SQL);
// Get session and and create hash map (fhMap is flight-hash-map)
HttpSession session = request.getSession();
HashMap<Long, UserFlightsBean> fhMap = new HashMap<Long, UserFlightsBean>();
while(rs.next()) {
int FlightNumber = rs.getInt("FlightNumber");
String Operator = rs.getString("Operator");
String Source = rs.getString("Source");
String DepartureTime = rs.getString("DepartureTime");
String Destination = rs.getString("Destination");
String ArrivalTime = rs.getString("ArrivalTime");
int Cost = rs.getInt("Cost");
int Seats = rs.getInt("SeatsAvailable");
// Get session, get UserFlightsBean, set session UserFlightsBean
UserFlightsBean ufb = new UserFlightsBean(FlightNumber, Operator, Source, DepartureTime, Destination, ArrivalTime, Cost, Seats);
fhMap.put((long) FlightNumber, ufb);
System.out.println(FlightNumber + "\t" + Operator + "\t" + Source + "\t" + DepartureTime + "\t" + Destination + "\t" + ArrivalTime + "\t" + Cost + "\t" + Seats + "\t");
}
// Add hash map "fhMap" to session bean
session.setAttribute("fhMap", fhMap);
As you can see, I create an object with the query, each row from the database is an object which I put into the hash map, then I add the hash map to the session so that I can access it on my jsp page.
On the jsp page I get the session hash map and now I'm trying to print out the elements of the objects, and this is where my problem lies. My code for the jsp page is below:
<%
HashMap <Long, UserFlightsBean> printMap = (HashMap <Long, UserFlightsBean>)session.getAttribute("fhMap");
pageContext.setAttribute("objects", printMap);
%>
<c:forEach items="${objects}" var="entry">
Key is ${entry.key} <%-- these two for testing purposes --%>
value = ${entry.value}<br>
<ul>
<c:forEach var="junk" items="${value.UserFlightsBean}">
<li>${junk.getFlightNumber()}</li>
</c:forEach>
</ul>
</c:forEach>
So what I'm trying to do is print (into a <li>) all the variables that are contained in that object. I've searched everywhere online, scowered the Stack Overflow waters, and cannot find out how to do this.
Thanks for any help one may provide!

Here , what i can understand, you need not to use inner loop...
You can write code like this:
`<c:forEach items="${objects}" var="entry">
Key is ${entry.key} <%-- these two for testing purposes --%>
<ul>
<li>${entry.value.getFlightNumber()}</li>
<li>${entry.value.getOperator()}</li>
<li>${entry.value.getSource()}</li>
</ul>
</c:forEach>`

Get Value of dynamically create dropdownlist in JSP

I am new to JSP and servlet for 1 month, and there are many things that I am still unsure off.. Inside a JSP, I have a dropdownlist(the values inside are grab from database) and it would be dynamically created on the number that the user keyed in. Example, the user key in 3, this digit would store in session, and 3 dropdownlist would be generated.
I am able to do this, however I am unable to grab the value of all the 3 dropdownlist in a servlet. and instead of getting 3 diff values, the output repeat the value of the first dropdownlist. Example "john,john,john" instead of "john, ken, andy".
JSP code:
<form action="Adding" method="post">
<%
session = request.getSession();
ProjectGroup projGrp1 = (ProjectGroup)session.getAttribute("PROJECTNAME");
//getMaxMember is the int that user keyed in
int staff =projGrp1.getMaxMember();
for(int i = 0; i < staff; i++) {
%>
<select name="list1" >
<%#page import="sit.bean.*,sit.data.*"%>
<%
GroupTaskManager mgr3 = new GroupTaskManager();
GroupTask[] at3 = mgr3.getCheckBox();
for(int g = 0; g < at3.length; g++) {
%>
<option><%=at3[g].getStaffName()%></option>
<%
}
%>
</select>
<%
}
%>
<input type="submit" name="submit">
</form>
In servlet:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
HttpSession session = request.getSession();
ProjectGroup projGrp = (ProjectGroup)session.getAttribute("PROJECTNAME");
int member = projGrp.getMaxMember();
String total = null;
for(int i=0; i< member; i++)
{
String names = request.getParameter("list1");
total += names + " , ";
}
PrintWriter pw = response.getWriter();
pw.write("<HTML><BODY>");
pw.write(total);
pw.write("</HTML></BODY>");
pw.close();
}
Can i set the downdownlist name like "list<%i%>", to set different id to each downdownlist? therefore i can retrieve each of them seperately???

In servlet you are getting same parameter every time which is list1 in loop.
and also in JSP creating dropdownlist with same name attribute,
that's why you are getting john,john,john instead of john, ken, andy.
Yes you can use list<%i%> to set different id as well as name
change your select with below in JSP
<select name="list<%=i%>" >
and for loop in servlet with below
for(int i=0; i< member; i++)
{
String names = request.getParameter("list1"+i);
total += names + " , ";
}
