Book Description

Business rules can help your business by providing a level of agility and flexibility. As a developer, you will be largely responsible for implementing these business rules effectively, but implementing them systematically can often be difficult due to their complexity. Drools, or JBoss Rules, makes the process of implementing these rules quicker and handles the complexity, making your life a lot easier!

This book guides you through all of the features of Drools, such as dynamic rules, the event model, and Rete implementation with high performance indexing. It will help you to set up the JBoss Rules platform and start creating your own business. It’s easy to start developing with Drools if you follow its real-world examples that are intended to make your life easier.

Starting with an introduction to the basic syntax that is essential for writing rules, the book will guide you through validation and human-readable rules that define, maintain, and support your business agility. As a developer, you will be expected to represent policies, procedures and. constraints regarding how an enterprise conducts its business; this book makes it easier by showing you it can be done.

A real-life example of a banking domain allows you to see how the internal workings of the rules engine operate. A loan approval process example shows the use of the Drools Flow module. Parts of a banking fraud detection system are implemented with Drools Fusion module, which is the Complex Event Processing part of Drools. This in turn, will help developers to work on preventing fraudulent users from accessing systems in an illegal way.

Finally, more technical details are shown on the inner workings of Drools, the implementation of the ReteOO algorithm, indexing, node sharing, and partitioning… Download Now »

Book Description

The secret weapon for attacking complexity in any project is to break it down into smaller, cohesive, and more easily digestible pieces. With Modular Java, you can easily develop applications that are more flexible, testable, maintainable, and comprehensible.

Modular Java is a pragmatic guide to developing modular applications using OSGi, the framework for dynamic modularity in Java, and Spring Dynamic Modules, an OSGi extension to the Spring Framework. You’ll start with the basics but quickly ramp up, creating loosely-coupled modules that publish and consume services, and you’ll see how to compose them into larger applications. Along the way, you’ll apply what you learn as you build a complete web application that is made up of several OSGi modules, using Spring-DM to wire those modules together.

Modular Java is filled with tips and tricks that will make you a more proficient OSGi and Spring-DM developer. Equipped with the know-how gained from this book, you’ll be able to develop applications that are more robust and agile. Download Now »

Book Description

For web developers used to wrestling with Java and XML, Grails is a breath of fresh air. Developers are instantly productive, picking up all the benefits of the Ruby-based Rails framework without giving up any of the power of Java.

Grails in Action is a comprehensive look at Grails for Java developers. It covers the nuts and bolts of the core Grails components and is jam-packed with tutorials, techniques, and insights from the trenches.

The book starts with an overview of Grails and how it can help you get your web dev mojo back. Then it walks readers through a Twitter-style social networking app-built in Grails, of course-where they implement high-interest features like mashups, AJAX/JSON, animation effects, full text search, rounded corners, and lots of visual goodness. The book also covers using Grails with existing Java technology, like Spring, Hibernate, and EJBs.

About the Author
Glen Smith has been involved in the Grails community since Grails 0.1 and launched the first public-facing Grails app (an SMS Gateway) on Grails 0.2. He is a regular on the Groovy and Grails speaking circuit, the co-host of the Grails podcast, and the man behind groovyblogs.org. Download Now »

Book Description

Developing powerful web applications with clean, manageable code makes the maintenance process much easier. Aspect-Oriented Programming (AOP) is the easiest and quickest way to achieve such results. Spring is the only Java framework to offer AOP features. The combined power of Spring and AOP gives a powerful and flexible platform to develop and maintain feature-rich web applications quickly.

This book will help you to write clean, manageable code for your Java applications quickly, utilizing the combined power of Spring and AOP. You will master the concepts of AOP by developing several real-life AOP-based applications with the Spring Framework, implementing the basic components of Spring AOP: Advice, Joinpoint, Pointcut, and Advisor.

This book will teach you everything you need to know to use AOP with Spring. It starts by explaining the AOP features of Spring and then moves ahead with configuring Spring AOP and using its core classes, with lot of examples. It moves on to explain the AspectJ support in Spring. Then you will develop a three-layered example web application designed with Domain-Driven Design (DDD) and built with Test-Driven Development methodology using the full potential of AOP for security, concurrency, caching, and transactions.
