That is a very easy thing to do.
Just get the jasperreports.jar file, add it to your class path and create a report using

JasperPrint print = JasperFillManager.fillReport(fileName, parameters, connection);
JRViewer viewer=new JRViewer(print);

fileName is the name of your .jasper file, parameters is a HashMap of the parameters required by your report.
JRViewer extends JPanel so you should know how to display it from there on.

So don't pass the connection. The fillReport method has lots of overloads.

Does your data bean extend a class that implements JRDatasource?

Thats what I am asking what I pass there in hat Argument , I just want to know how my application know that which sepecific jar file (bean file) get the Data for filling report

One approach is to make your class a JRDatasource. You could extend some of the already implemented classes. Read the API specs for all those classes and interfaces to see how to use them.
