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.

The Art of Micro Frontends. Build highly scalable, distributed web applications with multiple teams - Second Edition

Florian Rappl, Lothar Schöttner

The organizational pattern of micro frontends allows you to split web applications into multiple parts, where each part can be owned by an autonomous team. Each team can have its own development and deployment life cycle, allowing every part of an application to be shipped in isolation. Following the strategies outlined in this book, you can avoid complexity while increasing resilience for your frontend. This updated second edition will guide you through the patterns available to implement a micro frontend solution. You’ll learn about micro frontends, the different architecture styles, and their areas of use. Then, you’ll learn how to prepare teams for the change to micro frontends, as well as how to adjust the user interface (UI) design and your CSS styles for scalability. Starting with the simplest variants of micro frontend architectures, the book progresses from static approaches to fully dynamic solutions that allow maximum scalability with faster release cycles. In the concluding chapters, you’ll strengthen the security level of your micro frontend solution, while reinforcing your overall knowledge with real-world case studies relating to micro frontends. By the end of this book, you’ll be able to decide whether and how micro frontends should be implemented to achieve high scalability for your web app.
