Problem in using Enumeration

[namrata suri]

Hi,
I have written a jsp which accepts n number of paired values i.e
"labelname and labelvalue"

<%@ page language="java" session="true"%>

<form action=path.jsp method=post>
<% int num=Integer.parseInt(request.getParameter("labelnum"));
	String label,labelval;
   for(int i=0;i<num;i++){
    label="label"+i;   
    labelval="labelval"+i;
%>
<input type="text" name=<%=label %>>Enter the label name<br/>
<input type="text" name=<%=labelval %>>Enter the value<br/>

<% } %>
<input type="submit" value="submit">
</form>

Now, to catch these values I have written another jsp as follows

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
    <%@ page import="java.util.*" %>
    <%@ page import="java.io.*" %>
    <%@page import="java.net.*" %>
<%
String s="http://chart.apis.google.com/chart?";
String chs="chs=250x100&";
String cht="cht=p3&";
String chd="chd=t:";
String chl="chl=";
Enumeration parameters = request.getParameterNames();
   	    
        while(parameters.hasMoreElements()){
        	
            String labelname = (String)parameters.nextElement();
            System.out.println(labelname);
            String temp=request.getParameter(labelname);
            System.out.println(temp);
           // chl+=temp+',';
           // chd+=temp+',';
            
            
        }
        chd+='&';
        s+=cht+chd+chs+chl;
        out.print(s);
        
  %> 
  
 

Problem is that instead of giving me the output in order like

label0 'a'
labelval0 '40'
label1 'b'
labelval1 '50' etc etc

its giving me

label0 'a'
labelval1 '50'
labelval0 '40'
label1 'b'

I need the values in order because I have to use them for formation of a string. Since, the outputs are random in order...I m facing difficulty.

First you are doing too many things in JSP which would be refactored by using JSTL,EL etc.. and moving some code to a controller servlet. For your question, first you have to fix those typos like not quoting attribute values in tags and see how it works.
