javascript, servlets and SVG

Hi,
i hope i am posting this question in the right forum.
in an application i am developing, the user selects an input map
(in SVG format)[eg; map of India], a couple of data files
corresponding to the map he has chosen[area.txt and population.txt],
and some calculation he wants to be done [finding density]
the user make all these selections using a HTML form and
submits it to a server. on the server side, servlets extract the data
values from the input data[extract the area and population values of
each state from the text files], perform the necessary calculations
[calculates density by dividing each area value with the population
value] and obtains a result[ie density for each state].
now based on the result obtained, i want for a particular range of
output data [density], a color to be appplied on the map; for another
range, another color etc.
my questions are:
(1) can i use servlets to do the above coloring or
(2) should a javascript function be used to do the above color mapping
(3) if javascript is to be used, where should this javascript function
be in order to do the necessary calculation?
desperately waiting to hear from you.
thanks in advance.

i understand development is developing code but what does a person in maintanence actually do? does he need to develop any code?
and will a fresher like me(i have been recently selected in campus recrutiment by an IT biggie and will be joining them in a month) get into development or maintanence??

generating tags when submit button in clicked

Hi,
i have a simple javascript form with an image and a submit button in my 'home' page. when the image is clicked, the user is taken to another page, 'page2' where he has a form with a select tag and some options. these options allow him to select an image from set of images.
now the user selects one of the options and the image he has chosen is displayed on the screen using an appropriate function.
the user then clicks on a 'back' button and returns to the 'home' page. here when he clicks on the 'submit' button, a XML file showing his selection is to be displayed ie XML looks like
<choice>
<figure>D:\My Documents\af.jpg</figure>
</choice>
the figure tag is dynamic and changes depending on the value chosen by the user.
i have the code by which the above XML is generated but it works only in page2 ie as soon as the user makes his selection, the image is displayed and simultaneously the above XML is also generated in a separate window.
instead i want this XML to be generated ONLY WHEN THE USER CLICKS ON THE SUBMIT BUTTON in the home page.
thanks in advance.

the XML that is generated is written in a new window. now i want to save the XML file such that it is available to the serverside programs for processing.

generating dynamic XML

Hi,
i need ur advise on how to use XML for developing a simple application.
in my application, the user is presented with a HTML form by which he
can make necessary selections. the form template is given below:
<form name="theForm">
<select name="sel" onchange="loadFile();">
<option> Choose the map u prefer
<option value="C:\My Documents\usa.jpg">US
<option value="C:\My Documents\uk.jpg" >UK
<option value="C:\My Documents\spain.jpg">Spain
<option value="C:\My Documents\greece.jpg">Greece
</select>
</form>
in the above application , the user chooses a map and some data files and on the server side, some processing is done on the user selected map using the data also selected by the user and the final map is displayed back to the user.
i have been asked to use XML in the above situation(probably for data exchange!!). i need to design a XML file that encapsulates the choices made by the user and this XML file has to be sent to the server via HTTP.
the server-side programs are to interpret this XML file and do necessary procesing. my question is:
is it possible to design such a XML file? this XML file should be a dynamic one that should change each time the user makes selection using the form.
i posted this question in XML forum and was advised to post it in JavaScript forum for better responses. eagerly looking forward to ur suggestions.
thanks in advance

i need to necessarily use XML in the above scenario and i am in desperate need of ur advise and suggestions..

generating XML using servlets/jsp

Hi,
this is how i plan to write my XM file:
<?xml version="1.0" encoding="ISO-8859-1"?>
<userselection>
<fig id="1">C:\My Documents\usa.jpg</fig>
<fig id="2">C:\My Documents\uk.jpg</fig>
<fig id="3">C:\My Documents\spain.jpg</fig>
<fig id="4">C:\My Documents\greece.jpg</fig>
</userselection>
from the above XML file, using JSP/Servlet, i need to generate a dynamic XML file that captures only the selections made by the user.
is the above procedure right?
