jasper report scheduler api + zip attachment

[bhushan_makade]

Hi,

I am using jasper server 3.5 webservice API for scheduling reports from application.

We have a requirement of sending the report as zip attachment.  From API perspective i could not find a direct way

wherein i can specify to zip the particular report.

But when i dug into code, i found a code which is doing the compression/zip logic

Please see the attached code.

So , just wanted to know if my report has more than one file, then only jasper will implicitely do the compression of that report?

or is there any way i can specify to compress a report for me even if it has just one file?

 

 

 

Code:

protected void attachOutput(MimeMessageHelper messageHelper, ReportOutput output) throws MessagingException, JobExecutionException {		String attachmentName;		DataContainer attachmentData;		if (output.getChildren().isEmpty()) {			attachmentName = output.getFilename();			attachmentData = output.getData();		} else {			attachmentData = createDataContainer();			boolean close = true;			ZipOutputStream zipOut = new ZipOutputStream(attachmentData.getOutputStream());			try {				zipOut.putNextEntry(new ZipEntry(output.getFilename()));				StreamUtils.pipeData(output.getData().getInputStream(), zipOut);				zipOut.closeEntry();								for (Iterator it = output.getChildren().iterator(); it.hasNext();) {					ReportOutput child = (ReportOutput) it.next();					String childName = getChildrenFolderName(output.getFilename()) + '/' + child.getFilename();					zipOut.putNextEntry(new ZipEntry(childName));					StreamUtils.pipeData(child.getData().getInputStream(), zipOut);					zipOut.closeEntry();									}								zipOut.finish();				zipOut.flush();								close = false;				zipOut.close();			} catch (IOException e) {				throw new JSExceptionWrapper(e);			} finally {				if (close) {					try {						zipOut.close();					} catch (IOException e) {						log.error("Error closing stream", e);					}				}			}			attachmentName = output.getFilename() + ".zip";		}				try {			attachmentName = MimeUtility.encodeWord(attachmentName, getCharacterEncoding(), null);		} catch (UnsupportedEncodingException e) {			throw new JSExceptionWrapper(e);		}		messageHelper.addAttachment(attachmentName, new DataContainerResource(attachmentData));	}
