JasperReports 3.5 for Java Developers

David R Heffelfinger, David R. Heffelfinger, Teodor Danciu

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.

Mastering Blockchain Programming with Solidity. Write production-ready smart contracts for Ethereum blockchain with Solidity

Jitendra Chittoda

Solidity is among the most popular and contract-oriented programming languages used for writing decentralized applications (DApps) on Ethereum blockchain. If you’re looking to perfect your skills in writing professional-grade smart contracts using Solidity, this book can help.You will get started with a detailed introduction to blockchain, smart contracts, and Ethereum, while also gaining useful insights into the Solidity programming language. A dedicated section will then take you through the different Ethereum Request for Comments (ERC) standards, including ERC-20, ERC-223, and ERC-721, and demonstrate how you can choose among these standards while writing smart contracts. As you approach later chapters, you will cover the different smart contracts available for use in libraries such as OpenZeppelin. You’ll also learn to use different open source tools to test, review and improve the quality of your code and make it production-ready. Toward the end of this book, you’ll get to grips with techniques such as adding security to smart contracts, and gain insights into various security considerations. By the end of this book, you will have the skills you need to write secure, production-ready smart contracts in Solidity from scratch for decentralized applications on Ethereum blockchain.

Mastering Transformers. Build state-of-the-art models from scratch with advanced natural language processing techniques

Savaş Yildirim, Meysam Asgari- Chenaghlu

Transformer-based language models have dominated natural language processing (NLP) studies and have now become a new paradigm. With this book, you'll learn how to build various transformer-based NLP applications using the Python Transformers library.The book gives you an introduction to Transformers by showing you how to write your first hello-world program. You'll then learn how a tokenizer works and how to train your own tokenizer. As you advance, you'll explore the architecture of autoencoding models, such as BERT, and autoregressive models, such as GPT. You'll see how to train and fine-tune models for a variety of natural language understanding (NLU) and natural language generation (NLG) problems, including text classification, token classification, and text representation. This book also helps you to learn efficient models for challenging problems, such as long-context NLP tasks with limited computational capacity. You'll also work with multilingual and cross-lingual problems, optimize models by monitoring their performance, and discover how to deconstruct these models for interpretability and explainability. Finally, you'll be able to deploy your transformer models in a production environment.By the end of this NLP book, you'll have learned how to use Transformers to solve advanced NLP problems using advanced models.
