I have made a Java Swing application which produces an xml file with data from a mysql database.
Using that I have successfully made a Jasper (jrxml) report using the Jasper 5.5.0 plugin for NetBeans separately from my Swing application.
To do this I use the prepared xml file as datasource. So I have Jasper report with an xml datasource and one subreport. How can I run that .jasper report from my Swing application and export as a pdf file? As a final message box from my Swing app I get:
<em>"XML file is successfully generated"</em>
I want to make one button on that message box with option:
<em>"Print xml to pdf file"</em>
Where can I run my Jasper report and export as a pdf?
I have searched for examples using Google, but I can't find anything useful.
I found the solution:
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JasperCompileManager;
import net.sf.jasperreports.engine.JasperExportManager;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.JasperReport;
import net.sf.jasperreports.engine.JasperReportsContext;
import net.sf.jasperreports.engine.data.JRXmlDataSource;
public static void main(String[] args) {
try {
HashMap hm = new HashMap < > ();
String filePath = System.getProperty("user.dir") + "\\somexmldatasource.xml";
InputStream inputStream = new FileInputStream(new File(filePath));
JRXmlDataSource ds = new JRXmlDataSource(inputStream, "/some/xpath/query");
JasperReport jasperReport;
JasperPrint jasperPrint;
jasperReport = JasperCompileManager.compileReport(System.getProperty("user.dir") + "\\yourreport.jrxml");
jasperPrint = JasperFillManager.fillReport(jasperReport, hm, ds);
JasperExportManager.exportReportToPdfFile(jasperPrint, "someoutputpath\\simple_report.pdf");
} catch (Exception e) {
e.printStackTrace();
}
}
for using Jasper in java you must include several JARs from:
c:\Program Files (x86)\Jaspersoft\iReport-5.5.0\ireport\modules\ext\
(or some other path of iReport app)
The JARs to include are:
