Cisco Cisco Configuration Engine 3.5.3 Guida Dello Sviluppatore

Below is a simple programmatic example of posting XML to the servlet using the multipart/form-data 
MIME content type. This simple java class PostUtil.java utilizes an HTTPClient class library from 
http://www.innovation.ch/java/HTTPClient The jar file HTTPClient.jar (which can be obtained from the 
above URL) should be in the classpath.

In this client example, you would be posting to your host system with hostname beethoven a 
<cns-request> XML document that you had saved in a file import.xml to the following 
URL:http://beethoven/cns/CommandProcessor

import HTTPClient.*;

import java.io.*;

import java.net.*;

public class PostUtil

{

    public static void main(String[] args)

    {

        String _sHost       = "beethoven";

        String _sPort       = "80";

        String _sPath       = "/cns/CommandProcessor";

        String _sParamName  = "command";

        String _sFileName   = "import.xml";

                                                  _sFileName);

            System.out.println(_sResponse);

        }

        catch (Exception e)

        {

            e.printStackTrace();
