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

In this chapter, we learned how to export reports to all formats supported by JasperReports. We learned to export reports to PDF by taking advantage of the JRPdfExporter class. We also saw how to export reports to RTF/Microsoft Word by taking advantage of the JRRtfExporter class.

Similarly, to export reports to Microsoft Excel, HTML, and CSV formats we used the JExcelApiExporter, JRHtmlExporter, and JRCsvExporter classes respectively. The JRXmlExporter class of JasperReports provided us with the functionality to export our reports to the XML format.

Finally, we learned to export reports to Plain Text by taking advantage of the JRTextExporter class. However, the algorithm JasperReports uses to generate Plain Text reports does not always produce accurate results while mapping the report pixels to ASCII characters. The chapter also gave us an insight on how to direct HTML reports to a browser.
