We have seen in the previous chapter, how to print and view a JasperReport generated document. Here, we shall see how to transform or export these reports into other formats such as PDF, HTML, and XLS. Facade class net.sf.jasperreports.engine.JasperExportManager is provided to achieve this functionality. Exporting means transforming the JasperPrint object (.jrprint file) into different format.

The PDF exporter can encrypt the files using either a 40-bit key or a 128-bit key. By default, it uses a 40-bit key, but if you set this flag to Boolean.TRUE, it can be configured to use a 128-bit key for stronger encryption. From that menu, you should be able to export the fonts as jar, which you should include in your build path to embed the fonts within your java application. I also set the net.sf.jasperreports.default.pdf.embedded property to true, although that may not be necessary. Make sure you have a default style. Level 2 and level 3 headings are marked the same way, except that the properties are: net.sf.jasperreports.export.pdf.tag.h2 and net.sf.jasperreports.export.pdf.tag.h3. Marking Tables Tables are comprised of column headers, row headers, and a data section. Each table section is.

For the program im gettin some java.io.StreamCorruptedException: invalid stream header error. To export to the XLS format, we have used the class net.sf.jasperreports.engine.export.JRXlsExporter. This code generates following three files − This code generates following three files − sample_report.pdf.

The following code (JasperReportExport.java) demonstrates the exporting process of the JasperReport document. The JasperExportManager provides methods to export a report into PDF, HTML, and XML only. To export to the XLS format, we have used the class net.sf.jasperreports.engine.export.JRXlsExporter. This code generates following three files −

sample_report.pdf
sample_report.html
sample_report.xls

Exporting to Other Formats

Let's write a report template. The contents of the JRXML file (C:toolsjasperreports-5.0.1testjasper_report_template.jrxml) are as below −

Next, contents of the POJO file C:toolsjasperreports-5.0.1testsrccomtutorialspointDataBean.java are as given below −

The contents of the file C:toolsjasperreports-5.0.1testsrccomtutorialspointDataBeanList.java are as given below −

Write a main class file JasperReportFill.java, which gets the java bean collection from the class (DataBeanList) and passes it to the JasperReports engine, to fill the report template. Save it to the directory C:toolsjasperreports-5.0.1testsrccomtutorialspoint.

Here, we have included the logic to export the jasper print file to pdf, html and xls format.

Go to the command prompt and then go to the directory C:toolsjasperreports-5.0.1test, where build.xml is placed. Finally, execute the command ant -Dmain-class=com.tutorialspoint.JasperReportFill. The output is as follows −

As the result of above execution, you will find three files sample_report.pdf, sample_report.html, sample_report.xls generated in the C: directory.
