Using jasper-reports 5.6.1 I am able to generate the reports in pdf format, but I am not able figure out how to generate a .doc format by using jasper.
byte[] exportReportToPdf = JasperExportManager.exportReportToPdf(print);
is for generating a pdf format file like this is there any similar view class for doc format?
Try like this
JasperPrint jasperPrint = JasperFillManager.fillReport("myReport.jasper", reportParameters, dataSource);
Exporter exporter = new JRDocxExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
File exportReportFile = new File("D:\\Temp\\report.docx");
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput(exportReportFile));
exporter.exportReport();

Before executing a report, the JRXML must be compiled in a binary object called a Jasper file(*.jasper). This compilation is done for performance reasons. Jasper files are what you need to ship with your application in order to run the reports. Once the report is compiled it is filled with data from the application. The class net.sf.jasperreports.engine.JasperFillManager provides necessary functions to fill the data in the reports.
The report execution is performed by passing a Jasper file and a data source to JasperReports. There are plenty of types of data sources, it's possible to fill a Jasper file from an SQL query, an XML file, a csv file, an HQL (Hibernate Query Language) query, a collection of Java Beans, etc... If you don't find a suitable data source, JasperReports is very flexible and allows you to write your own custom data source.
JasperFillManager.fillReportToFile( "MasterReport.jasper" , parameters, getDataSource());
This operation creates a Jasper print file (*.jrprint), which used to either print or export the report.

We are using hbs(handlebars) formatted template on the backend side of the project for generate pdf file. What I want is this. Is there an option to create the hbs file with the data in it when the file is created? For example the hbs file in the following should be like this:
hbs before creation
<h4>address1:{{address1}}</h4>
<h4>address2:{{address2}}</h4>
<h4>city:{{city}}</h4>
<h4>state :{{state}}</h4>
hbs after creation
<h4>address1:value</h4>
<h4>address2:value</h4>
<h4>city:value</h4>
<h4>state :value</h4>

Jasper report exports empty data in PDF format when there is more data
(5 answers)
Closed 4 years ago.
Using a Jaspersoft Studio 6.6.0 I created a very simple report with a static text and a red rectangle (as well as many other things I tested before). There is no query to fetch data, no dynamic field or anything.
This is what the design looks like:
Preview looks fine in all different formats (HTML, PDF etc..)
The problem I have comes when I try to generate the report in my web app. Using a library version 6.7.0.
HTML Export coded like this yields an empty String
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params);
StringBuilder htmlStringBuilder = new StringBuilder();
HtmlExporter exporter = new HtmlExporter();
SimpleHtmlExporterConfiguration conf = new SimpleHtmlExporterConfiguration();
conf.setHtmlHeader("");
conf.setBetweenPagesHtml("");
conf.setHtmlFooter("");
conf.setFlushOutput(true);
exporter.setConfiguration(conf);
SimpleHtmlExporterOutput output = new SimpleHtmlExporterOutput(htmlStringBuilder);
exporter.setExporterOutput(output);
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.exportReport();
return htmlStringBuilder.toString(); // empty string
Eport to PDF using creates a single page PDF file. The page is blank.
JasperExportManager.exportReportToPdfFile(jasperPrint, "file.pdf");
I tried to compile the JRXML file using both the Studio and also in the Java code. The result is still the same. JasperPrint object seem to be populated, however no elements are present on the page, which I reckon is related. Any chance to find out why?
I see two options for this:
In your java code import the net.sf.jasperreports.engine.JREmptyDataSource class and fill the jasperPrint like so:
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, new JREmptyDataSource());
This should guarantee that your detail band is displayed once. This is what JasperSoft Studio uses when you preview a report with One Empty Record Data Adapter.
In JasperSoft Studio, move all the content out of the Detail band to Summary band, for example, and in Report Properties tab select:
When No Data Type: All Sections No Detail
This way all the other bands, except the Detail one, will be rendered when you don't provide any data.
So, I'm trying to save the pdf report in database using service methode. I saw that there's a way to specify the output of the generated report by calling : pdfOptions.setOutputStream(output). But how can I call my save methode this way?
I saw this post but i'm stack at the persist point
I apreciate any advice
PDFRenderOption pdfOptions = new PDFRenderOption(options);
pdfOptions.setOutputFormat(FORMAT_PDF);
pdfOptions.setOption(IPDFRenderOption.PAGE_OVERFLOW, IPDFRenderOption.OUTPUT_TO_MULTIPLE_PAGES);
pdfOptions.setOutputStream(response.getOutputStream());//opens report on browser
runAndRenderTask.setRenderOption(pdfOptions);
You are streaming the output directly to the client with
pdfOptions.setOutputStream(response.getOutputStream());//opens report on browser
If you do this, your output gets consumed and you'll not be able to save it to the database.
I would use a "tee" like approach, you know, with one input stream and two output streams.
You could write that yourself, our you just use something like the Apache TeeOutputStream.
This could look like this:
OutputStream blobOutputStream = ...; // for writing to the DB as BLOB.
OutputStream teeStream = TeeOutputStream(response.getOutputStream(), blobOutputStream);
pdfOptions.setOutputStream(teeStream);
So I summarize my problem. I would like to convert an xls file to PDF, while using java. .
I find two examples
The first is with Openoffice
import officetools.OfficeFile; // from officetools.jar
FileInputStream fis = new FileInputStream(new File("test.doc"));
FileOutputStream fos = new FileOutputStream(new File("test.pdf"));
OfficeFile f = new OfficeFile(fis,"localhost","8100", false);
f.convert(fos,"pdf");
But unfortunately I have to install it :(
I also find this example, two command line with vb (call pdf creator)
DoCmd.OpenReport "repClient", acViewPreview, "NumClient = 2"
DoCmd.OutputTo acOutputReport, "PDF", "d: \ test.pdf"
is there somthing like that on java !!!!
(Note I used for my first solution (jxl, appach poi) but formatting pdf generated is not like when I do save as PDF with Microsoft Excel)
think you in advance
I think you can stream the data from the excel document using
apache POI
library. You can pass this stream of data in
iText library API.
iText library API definitely has a function which writes stream data into PDF file. With iText, you can be sure of pdf formatting as it is widely used in organizations for PDF generation. Infact many reporting tool also use iText to generate PDF reports.
I want to know do JasperServer accepts xml file as the report data source and whether we can perform same operation on xml nodes that we perform on the various data-source in adhoc report creator like dragging dropping etc.?
yes, jasper does support XML based datasources, you can create your report just the way you would create it using any other datasource. Jasper has an abstraction from datasources which you provide to ensure it behaves the same (or atleast similarly) with different datasources.
look here and here for some additional info
Here is the sample Code I tested for xml file as data source and out is PDF report:
JasperReport jasperReport = JasperCompileManager.compileReport("<Path of jrxml file>");
JRXmlDataSource xmlDataSource = new JRXmlDataSource("<Path of xml file>", "XPath Query");
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, new HashMap(), xmlDataSource);
JasperExportManager.exportReportToPdfFile(jasperPrint, "<Path of file PDF output file>");
