Overview of this book

JasperReports is the world's most popular embeddable Java open source reporting library, providing Java developers with the power to easily create rich print and web reports. This book shows you exactly how to get started, and develop the skills to get the most from JasperReports. The book steers you through each point of report setup, to creating, designing, formatting, and exporting reports with data from a wide range of datasources, and integrating JasperReports with other Java frameworks. Starting with the basics of adding reporting capabilities to your application, and creating report templates you will first see how to produce your reports through the use of JRXML files, custom ANT targets, and then see preview them in both the browser and the native browser of JasperReports. Getting data into your reports is the next step, and you will see how to get data from a range of datasources, not only databases, but XML files, and Java Objects, among others. You will create better looking reports with formatting and grouping, as well as adding graphical elements to the report. You will export your reports to a range of different formats, including PDF and XML. Creating reports will be made even easier with a walkthrough of the iReport Designer visual designing tool. To round things off, you will see how to integrate your reports with other Java frameworks, using Spring or Hibernate to get data for the report, and Java Server Faces or Struts for presenting the report.

Java Objects as Datasources

In addition to databases and maps, JasperReports allows us to use Plain Old Java Objects (POJOs) as datasources. We can use any Java object that adheres to the JavaBeans specification as a datasource. The only requirements for an object to adhere to the JavaBeans specification are that it must have no public properties, it must have a no-argument constructor, and it must provide getter and setter methods to access its private and protected properties. Let us create a Java object that can be used as a datasource for our next example:

package net.ensode.jasperbook;
public class AircraftData
{
public AircraftData(String tail, String serial, String model, String engine)
{
setTailNum(tail);
setAircraftSerial(serial);
setAircraftModel(model);
setEngineModel(engine);
}
public AircraftData()
{
}
private String tailNum;
private String aircraftSerial;
private String aircraftModel;
private String engineModel;
public String getAircraftModel()
{
return aircraftModel;
}
public...
