Report name: report.jrxml. In the java code add all the jar files required to build the project from jasper installed directory.


In java class write the following piece of code:
package local;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.HashMap;
import java.util.Locale;
import java.util.Map;

import net.sf.jasperreports.engine.JRDataSource;
import net.sf.jasperreports.engine.JREmptyDataSource;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JRParameter;
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;

public class JasperReportFillI18 {

public static void main(String[] args) throws JRException, InstantiationException, IllegalAccessException, ClassNotFoundException, SQLException {

String sourceFile = args[0]; //jrxml file path
String locale = args[1];//language
String outputDirectory = args[2];//output file path directory
String outputFileName = args[3];// output file path directory with  file name
JasperReport jp = JasperCompileManager.compileReport(sourceFile);
// calling exportReportToPdf method
//exportReportToPDF(jp, outputDirectory, outputFileName, locale);
File outDir = new File(outputDirectory);
JasperPrint jasperPrint = null;
Connection con = null;
// Export to PDF.

try {
//database connection
Connection datasource = DriverManager.getConnection(
“jdbc:postgresql://localhost:5433/foodmart”, “postgres”,

HashMap parameterMap = new HashMap();
//Preparing parameters
parameterMap.put(JRParameter.REPORT_LOCALE, new  Locale(locale));
//parameterMap.put(“year”, 1961);
//parameterMap.put(“DataFile”, “”);
jasperPrint = JasperFillManager.fillReport(jp, parameterMap,

//for empty datasource
 //jasperPrint = JasperFillManager.fillReport(jp, parameterMap, new JREmptyDataSource());

} catch (JRException e) {
// TODO Auto-generated catch block
System.out.println(“Job has finished::!!”);
Configure the run time arguments in run configurations consider the following example:
“E:/Ireport Reports/local_test.jrxml””en_US””E:/Ireport Reports””E:/Ireport Reports/test.pdf”
Execute the java application to see the final output in pdf format in the path provided in arguments.
