virtualizer file causing disc full

[suryakantmandal]

I am using JRFileVirtualizer to prepare the report but its creating thousands of temp files virt**** which is creating disc full problem on server.

I have called virtualizer.cleanup(); to clean the files created post the report has generated but this also not delteing the temp files.

Is there any way to get the names of temp files created so that I can ran manual cleanup matching those name before ending the process.

if(outputType.equals(OutputTypeEnum.EXCEL))
       {
          JasperFillManager jasperFillManager = JasperFillManager.getInstance(DefaultJasperReportsContext.getInstance());
          JasperPrint jasperPrint = jasperFillManager.fill(reportStream, parameterMap, connection);

          JRXlsExporter exporter = new JRXlsExporter();
         exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
         exporter.setParameter(JRExporterParameter.OUTPUT_FILE_NAME, outputFilename);
         exporter.exportReport();
         result.setReportContent(FileUtils.readFileToByteArray(new File(outputFilename)));
         result.setOutputFile(new File(outputFilename));
       }

====

JRFileVirtualizer virtualizer = new JRFileVirtualizer(VIRTUAL_PAGE_SIZE, makeTempDirectory()); 
      parameters.put(JRParameter.REPORT_VIRTUALIZER, virtualizer);

 

Thanks,

Surya

Instead, how about specifying the location of the temporary file directory in the jvm with "-Djava.io.tmpdir" option and the deleting every file in that directory?

@howza If multiple repors are running simultaneously then cleaning the entire directory will delete the virtual files of another report which may be still in progress.
