import net.sf.jasperreports.engine.JREmptyDataSource;
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.view.JasperViewer;
import org.apache.commons.digester.Digester;
import net.sf.jasperreports.engine.design.*;
import net.sf.jasperreports.engine.*;
import java.util.*;

public class Report
{
public void viewReport()
{


String reportSource
= "HelloReportWorld.jrxml";
String reportDest
= "HelloReportWorld.html";
String name=null;
System.out.println("Hello World!");
Map<String, String> params = new
HashMap<String, String>();
params.put("reportTitle", "Shabbir
Ahmed");
params.put("author", "shabbir");
params.put("startDate", (new
java.util.Date()).toString());

System.out.println("here1111111");
try
{
System.out.println
("here222222222");

JasperDesign jasperDesign =
JasperManager.loadXmlDesign
("D:/Tomcat/bin/HelloReportWorld.jrxml");
JasperReport jasperReport
=JasperCompileManager.compileReport(jasperDesign);

JasperPrint jasperPrint
=JasperFillManager.fillReport(jasperReport, params, new
JREmptyDataSource());


JasperExportManager.exportReportToHtmlFile
(jasperPrint, reportDest);

JasperViewer.viewReport
(jasperPrint);


}

catch (JRException ex)
{
System.out.println
("here6666666666666");
ex.printStackTrace();
}
catch(Exception e)
{
System.out.println
(e.getMessage());
}
}
