JasperReports for Java Developers

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.

Summary

The chapter starts with integrating JasperReports with Hibernate by writing embedded report queries in the Hibernate Query Language (HQL). JasperReports with HQL queries is similar to reports containing SQL queries except that the language attribute of the<queryString> element must be set to hql. Next, we saw how to integrate JasperReports with the Spring framework by taking advantage of Spring's built-in JasperReports integration.

The chapter also dealt with JavaServer Faces and JasperReports integration and illustrated how to write backing beans that fill a report and display it in the browser. Finally, the chapter illustrated the integration of JasperReports with Struts by explaining how to write action classes that fill a report and display it in the browser.
