How to read an XML from a servlet?

Question

Hi,
I'm just starting programming and now I have a problem I can't solve. I hope someone can help me.</p>
On the client side I have a xml report and a script wich sends to the server the information I've got from the report. In this case, the 'Poliza' value.
On the server-side I have a servlet. I try to get the parameters (from the URL or from the XML), but I don't have any response on the client side. I'm sure I'm doing something wrong but I can't find the solution for solving it.
I suppose there are two ways of solving the problem.
- Make an http connetion and send just the parametes on the URL? Does anyone know how to make it?
- Reading the XML on the servlet and extract the parameters the script sent. Does anyone know how to read it?
Thank you in advance
I attach part of the code.
CLIENT SIDE
<report....>
<field sortid="0" id="Poliza" inputtype="textbox" label="Poliza" rows="1" wide="false" required="false"/>
</report>
<script name="ValidacionOnlineValidation1" script="if (0 == 0){
var szURL="http://URLServer/vonline/vonline?Poliza="+Poliza.value;
var szUserAgent = "JoP-XML_Posting_v1.0";
var m_XML;
/* In the line below, construct a XML-document that contains all the information you need to send to the server*/
var szXML = "<?xml version=\"1.0\"?><data><objects><object name=\"Poliza\" value=\"123456789\"/></objects></data>";
/* Create an instance of the MS XML Document Object Model Parser*/
m_XML= new ActiveXObject("Microsoft.XMLDOM");
m_XML.validateOnParse=true;                                                                                                         
var bLoadResult = m_XML.loadXML(szXML);
if (bLoadResult==true) {
  /*Instance of the transport object, method,...*/
  var m_HttpReq = new ActiveXObject("Pocket.HTTP");
  m_HttpReq.method = "GET";
  m_HttpReq.Headers.create("Content-Type", "text/xml");
  m_HttpReq.Headers.find ("User-Agent").Value = szUserAgent;
  m_HttpReq.timeout = 150000;
  /*Do the actual post of the data*/
  var m_HttpResponse = m_HttpReq.GetResponse(szURL,m_XML.xml);
  if (m_HttpResponse.statusCode==200) {...}
SERVER SIDE
protected void processRequest(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
     String Error="";
     String MSG = "";
     response.setContentType("text/html");
     PrintWriter out1 = response.getWriter();
     Enumeration arrayparametros = request.getParameterNames();
     for (;arrayparametros.hasMoreElements();){
          String parametro = (String)arrayparametros.nextElement();
          String valorparametro = request.getParameter(parametro);
          if (parametro.equals("Poliza")){
               vonlineLogica logica = new vonlineLogica();
               LOGS ="on";
               Respuesta respuesta = logica.procesarSolicitud(request,valorparametro);
               Error = Respuesta.getError();
               MSG = Respuesta.getMensaje();
          else{          
               Error = parametro; MSG = valorparametro;
               String[] values = request.getParameterValues(parametro);
     out1.println("Result: " + Error + " / " + MSG);
     out1.close();                    
}

Thanks by your help Shanu.
Nevertheless, finally I tryed the easiest way (pass the parameter with 'GET'). Moreover I found why my code wasn't working. It was a fool thing. I though PDA connect throught a proxy, but it wasn't true. Whatever.

The final script on the xml-report is:
<report type="Validacion Online" required="false" multiple="false" attachments="false" scriptref="store://this/reportdef/script[@name='ValidacionOnlineValidation1']">
     <field sortid="0" id="Poliza" inputtype="textbox" label="Poliza" rows="1" wide="false" required="false"/>
</report>
<script name="ValidacionOnlineValidation1" script="if (0 == 0)
var szURL="http://URL/vonline/vonline?parameter1=";+Poliza.value;                         
var m_HttpReq = new ActiveXObject("Pocket.HTTP");                                             m_HttpReq.timeout = 15000;
var m_HttpResponse = m_HttpReq.GetResponse(szURL,"");
window.alert(m_HttpResponse.string);
if (m_HttpResponse.statusCode==200)  {....}
else {....}
