    public FormLoginDemo() {
        super();
    }

    public static void main(String[] args) throws Exception {

        HttpClient client = new HttpClient();
        client.getHostConfiguration().setHost(LOGON_SITE, LOGON_PORT, "http");
        client.getState().setCookiePolicy(CookiePolicy.COMPATIBILITY);
     	// 'developer.java.sun.com' has cookie compliance problems
        // Their session cookie's domain attribute is in violation of the RFC2109
        // We have to resort to using compatibility cookie policy

        GetMethod authget = new GetMethod("/xyz/");


        client.executeMethod(authget);
        System.out.println("Login form get: " + authget.getStatusLine().toString()); 
        // release any connection resources used by the method
        authget.releaseConnection();
        // See if we got any cookies
        Cookie[] initcookies = 
          client.getState().getCookies(LOGON_SITE, LOGON_PORT, "/xyzr/", false);

        // release any connection resources used by the method
        authpost.releaseConnection();

serevr side code :---

 DiskFileUpload fu = new DiskFileUpload();
        // If file size exceeds, a FileUploadException will be thrown
        fu.setSizeMax(1000000);
           Iterator itr=null;
try
{
        List fileItems= fu.parseRequest(request);

    itr = fileItems.iterator();
     
            fileItems = fu.parseRequest(request);
        } catch (FileUploadException ex) {
            Logger.getLogger(ExtendedUploadZippedResourcesAction.class.getName()).log(Level.SEVERE, null, ex);
        }

        while(itr.hasNext()) {
          FileItem fi = (FileItem)itr.next();

          //Check if not form field so as to only handle the file inputs
          //else condition handles the submit button input
          if(!fi.isFormField()) {
            System.out.println("\nNAME: "+fi.getName());

In the future, please UseCodeTags when posting code of any length. It's too hard to read without them. I've added them for you.

Take a look at the other methods of the FileItem class. The easiest to use would be write, but the various getXYZ methods might also be of interest.
