parameter in swap file. however i am getting error . Please advice.it will be great help.

I can not find any documentation on this on any site. Can anyone point me in the right direction? Code: if (VITUALIZER_SWAP_FILE.equals(virtualizerType)){ // creating the virtualizer JRSwapFile swapFile = new JRSwapFile(cacheDir, 2048, 1024); //JRSwapFile swapFile = new JRSwapFile( getServletContext().getRealPath("/reports/operationalreports/"), 1024, 1024); JRSwapFileVirtualizer virtualizer = new JRSwapFileVirtualizer(3, swapFile, true); parameters.put(JRParameter.REPORT_VIRTUALIZER, virtualizer); }long start = System.currentTimeMillis(); JasperPrint jasperPrint = JasperFillManager.fillReport(testReport,parameters,dataSource); long end=System.currentTimeMillis(); System.out.println("Filling time : " + ((end - start)/1000));
