        //Open report.
        oReportClientDocument.open(reportName, 0);

        //Get the report source
       IReportSource oReportSource = oReportClientDocument.getReportSource();

   
    //Set the export options to export to the format of choice. 
    ExportOptions oExportOptions = new ExportOptions();
   oExportOptions.setExportFormatType(ReportExportFormat.crystalReports);   
      

    ReportExportControl oReportExportControl = new ReportExportControl();

    //Pass the report source to the ReportExportControl and set the ExportOptions
    oReportExportControl.setReportSource(oReportSource);
   oReportExportControl.setExportOptions(oExportOptions);

    oReportExportControl.setExportAsAttachment(false);
    //Pass the ConnectionInfo to the report to set the database username and password
    oReportExportControl.setDatabaseLogonInfos(oConnectionInfos);

    //Pass Fields object to ReportExportControl
    oReportExportControl.setParameterFields(oFields);
   
   

   oReportExportControl.processHttpRequest(request, response,getServlet().getServletContext(), null);
 
               try
            {
                 
                  RequestContext re=new RequestContext();
                    
        InputStream in = oReportClientDocument.getReportSource().export(oExportOptions,re);
      OutputStream outt = new FileOutputStream("\\\\localhost\\d$\\"+reportname+".rpt");
                 
                    
                      byte[] buf = new byte[1024];
                 
                // Transfer bytes from in to out
             
                int len;
                while ((len = in.read(buf)) > 0) {
                    outt.write(buf, 0, len);
                }
       
      
                       in.close();
                       outt.close();
                      System.out.println("File copied.");
                     
                     
                      /////////////////////////////////////////////
