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.

Exporting to RTF

Rich Text Format (RTF) is a document file format that is supported by most word processors. Exporting to RTF allows our documents to be read by Microsoft Word and several other word processors.

Note

Unfortunately, RTF documents generated by JasperReports are not always readable by OpenOffice.org or StarOffice writer, since these office suites are not fully compliant with the RTF specification.

In the following example, we will export a report to RTF format.

package net.ensode.jasperbook;
import java.io.File;
import net.sf.jasperreports.engine.JRException;
import net.sf.jasperreports.engine.JRExporterParameter;
import net.sf.jasperreports.engine.JasperPrint;
import net.sf.jasperreports.engine.export.JRRtfExporter;
import net.sf.jasperreports.engine.util.JRLoader;
public class RtfExportDemo

{
public static final String REPORT_DIRECTORY = "reports";
public void rtfExport(String reportName)

{
File file = new File(REPORT_DIRECTORY + "/" + reportName + &quot...
