A Simple Program

In conclusion, following is an example of a simple program that shows how to produce a PDF file from a Jasper file using a data source named JREmptyDataSource, a utility data source that provides zero or more records without fields. The file test.jasper, referenced in the example, is the compiled version of the code in A simple JRMXL file example.

JasperTest.java

 
import net.sf.jasperreports.engine.*;
import net.sf.jasperreports.engine.export.*;
import java.util.*;
public class JasperTest
{
	public static void main(String[] args)
	{
		String fileName = "/devel/examples/test.jasper";
		String outFileName = "/devel/examples/test.pdf";
		HashMap hm = new HashMap();
		try
		{
			JasperPrint print = JasperFillManager.fillReport(
				fileName,
				hm,
				new JREmptyDataSource());
			JRExporter exporter = 
				new net.sf.jasperreports.engine.export.JRPdfExporter();
 
			exporter.setParameter(
				JRExporterParameter.OUTPUT_FILE_NAME,
				outFileName);
			exporter.setParameter(
			JRExporterParameter.JASPER_PRINT,print);
			exporter.exportReport();
			System.out.println("Created file: " + outFileName);
		}
		catch (JRException e)
		{
			e.printStackTrace();
			System.exit(1);
		}
		catch (Exception e)
		{
			e.printStackTrace();
			System.exit(1);
		}
	}
}
