Same Jasper Report keeps opening

[Mike Firkser]

I'm using Jasper Reports in a J2EE Web Application that produces reports in either .pdf or .xls format (user's choice). Here is the problem. If a run a report that produces an .xls file, if I don't close that .xls file, everytime I run any other report, the same xls file will appear in the new window.

When I check my Weblogic console, system print lines show the proper file being accessed. Is there something that I'm missing?

See code from servlet below.

JasperReport jasperReport = null;
JasperPrint jasperPrint = null;
HashMap<String, String> parameters = new HashMap<String, String>();
Connection conn = null;;
. 
.
.
try {
   conn = OracleDAOFactory.getConnection();
   jasperReport = JasperCompileManager.compileReport(inputFile);
   jasperPrint = JasperFillManager.fillReport(jasperReport,
                  parameters, conn);
   if (isPdf) {
      System.out.println("PDF line 118");
      JRExporter exporter = new JRPdfExporter();
      res.setContentType( "application/pdf" );
      res.getOutputStream().flush();
      exporter.setParameter(JRExporterParameter.OUTPUT_STREAM,
                     res.getOutputStream());
      exporter.setParameter(JRExporterParameter.JASPER_PRINT,
                     jasperPrint);
      exporter.exportReport();
      System.out.println("Finished is isPdf");
   }
   else if (isXL) {
      System.out.println("XL");
      res.setContentType("application/vnd.ms-excel");
      JRXlsExporter exporter = new JRXlsExporter();
      exporter.setParameter(JRExporterParameter.OUTPUT_STREAM,
                     res.getOutputStream());
       exporter.setParameter(JRExporterParameter.JASPER_PRINT,
                     jasperPrint);
       exporter.exportReport();
    }
} 
catch (Exception e) {
            System.out.println(e.getClass().getName() + " Exception");
            e.printStackTrace();
} 
finally {
   try {
     System.out.println("7");
     conn.close();
     res.getOutputStream().close();
     System.out.println("8");
               
    } catch (SecurityException e) {
     e.printStackTrace();
   }
