//this code is very easy any one can understand easily
//1. these are the packages which we need to import
import net.sf.jasperreports.engine.JasperCompileManager;
import net.sf.jasperreports.engine.JasperFillManager;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.JasperReport;
import net.sf.jasperreports.engine.design.JRDesignQuery;
import net.sf.jasperreports.engine.design.JasperDesign;
import net.sf.jasperreports.engine.xml.JRXmlLoader;

try{
Connection con=(Connection)
Connectivity.makeconnection();// Database Connection

File path=new File("Report/");
JasperDesign jasperDesign =
JRXmlLoader.load(path.getAbsolutePath()+"\\allbooksreport.jrxml");//here
allbooksreport is my jrxml file name ...//xml file

Map parameters = new HashMap();
parameters.put("DataSource" ,con);
JRDesignQuery query =new JRDesignQuery();
query.setText("select * from add_book");
jasperDesign.setQuery(query);
JasperReport jasperReport =
JasperCompileManager.compileReport(jasperDesign);
JasperPrint jasperPrint =
JasperFillManager.fillReport(jasperReport,parameters,con);
JasperViewer vwrpt = new
JasperViewer(jasperPrint,false);
vwrpt.show(); //...//view the report
vwrpt.setTitle("All Books Report");
