JasperReports 3.5 for Java Developers

Overview of this book

Do you want to create easily understood, professional, and powerful reports from disordered, scattered data using a free, open source Java class library? If your answer is yes, this book on JasperReports is what you are looking for. 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. The book has been fully updated to use JasperReports 3.5, the latest version of JasperReports. Previously accepted techniques that have now been deprecated have been replaced with their modern counterparts. All examples in the book have been updated to use XML schemas for report templates. Coverage of new data sources that JasperReports now supports has been added to the book. Additionally, JasperReports can now export reports to even more formats than before and exporting reports to these new formats is covered in this new edition of the book. This book shows you exactly how to get started, and develop the skills to get the most from JasperReports. It introduces you to the latest version of JasperReports, and gets you creating complex and elegant reports. The book steers you through each point of report setup, to creating, designing, formatting, and exporting reports with data from a wide range of data sources, 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 preview them in both the web 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 data sources, 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 your reports. 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. All examples have been updated to use XML schemas. New export formats, such as OpenDocument Text, and new data sources now supported by JasperReports are now covered in this updated edition.

Setting up iReport


iReport can help us quickly generate database reports. To do so, we need to provide it with the JDBC driver and connection information for our database.

iReport comes bundled with JDBC drivers for several open source relational database systems, such as MySQL, PostgreSQL, HSQLDB, and others. If we want to connect to a different database, we need to add the JDBC driver to iReport's CLASSPATH. This can be done by clicking on Tools | Options and then selecting the Classpath tab.

To add the JDBC driver to the CLASSPATH, click on the Add JAR button, and then navigate to the location of the JAR file containing the JDBC driver. Select the JAR file and click on the OK button at the bottom of the window.

Note

We won't actually add a JDBC driver, as we are using MySQL for our examples, which is one of the RDBMS systems supported out of the box by iReport. The information just provided is for the benefit of readers using an RDBMS system that is not supported out of the box.
