OSGi in Action: Creating Modular Applications in Java by Richard Hall, Karl Pauls, Stuart McCulloch, David Savage

By Richard Hall, Karl Pauls, Stuart McCulloch, David Savage

What is OSGi? easily positioned, OSGi is a standardized expertise that permits builders to create the hugely modular Java functions which are required for firm improvement. OSGi enables you to set up, commence, cease, replace, or uninstall parts with no taking down your whole procedure. The curiosity in OSGi established functions has exploded in view that significant owners like sunlight, Spring, Oracle, BEA, and IBM have got in the back of the standard.

OSGi in Action is a accomplished consultant to OSGi with basic ambitions. First, it offers a transparent advent to OSGi ideas with examples which are suitable either for architects and builders. Then, it explores quite a few useful eventualities and strategies, answering questions like: How a lot of OSGi do you really need? How do you embed OSGi within different boxes? What are the easiest practices for relocating legacy platforms to OSGi?

buy of the print publication comes with a suggestion of a loose PDF, ePub, and Kindle publication from Manning. additionally to be had is all code from the book.

Java 7 Concurrency Cookbook

Over 60 uncomplicated yet tremendously potent recipes for getting to know multithreaded program improvement with Java 7
* grasp all that Java 7 has to supply for concurrent programming
* become familiar with thread administration, the Fork/Join framework, concurrency sessions and masses extra during this booklet and booklet
* a pragmatic Cookbook choked with recipes for reaching crucial Java Concurrency projects

In aspect

Java is still the worldwide average for constructing quite a few functions and firm software program, and the release of Java 7 brings with it interesting new features for concurrent programming when it comes to the concurrency utilities enhancement. this enables builders to utilize their functions with parallel activity functionality. "Java 7 Concurrency Cookbook" covers all parts of the Java concurrency API, offering crucial recipes for making the most of the intriguing new capabilities.

On your desktop, you could hearken to song whenever you edit a notice rfile and browse your emails, without notice! the reason is, your working method permits the concurrency of projects, very similar to the Java platform which deals numerous periods to execute concurrent initiatives within a Java application. "Java 7 Concurrency Cookbook" covers an important positive aspects of the Java concurrency API, with distinct emphasis at the new functions of model 7.

With every one model, Java raises the to be had performance to facilitate improvement of concurrent courses. This publication covers crucial and beneficial mechanisms integrated in model 7 of the Java concurrency API, so that you can be capable of use them without delay on your applications.

"Java 7 Concurrency Cookbook" contains recipes to show you how to in achieving every little thing from the fundamental administration of threads and projects, to the hot Fork /Join framework, via synchronization mechanisms among projects, types of concurrent projects that Java can execute, facts buildings that needs to be utilized in concurrent functions and the periods of the library that may be customized.

With the step by step examples during this e-book you’ll be ready to observe crucial and valuable good points of the Java 7 concurrency API.

What will you research from this booklet
* grasp the fundamentals of thread administration and synchronization earlier than diving into greater point concurrency initiatives
* become familiar with interesting new concurrency positive factors of Java 7, together with the Phaser type and the Fork/Join Framework
* effectively delegate thread administration to executors
* customise probably the most precious periods of the Java concurrency API with real-world examples
* discover ways to use high-level Java utilities to control synchronization among threads
* Get a sneak peek at utilizing Eclipse and NetBeans for debugging concurrency code
* stay away from issues of facts inconsistency by way of studying the information buildings you might want to use in concurrent purposes
* benefit from an advantage appendix jam-packed with information that each programmer should still think about while constructing a concurrent software


"Java 7 Concurrency Cookbook" is a pragmatic Cookbook choked with real-world recommendations. Intermediate–advanced point Java builders will research from task-based recipes to take advantage of Java’s concurrent API to application thread secure solutions.

Making Java Groovy


Making Java Groovy is a pragmatic instruction manual for builders who are looking to combination Groovy into their daily paintings with Java. It begins through introducing the main changes among Java and Groovy—and how one can use them for your virtue. Then, it courses you step by step via reasonable improvement demanding situations, from net purposes to net prone to machine purposes, and indicates how Groovy makes them more straightforward to place into production.

About this Book

You don't desire the total strength of Java while you're writing a construct script, an easy procedure application, or a light-weight net app—but that's the place Groovy shines brightest. This dependent JVM-based dynamic language extends and simplifies Java so that you can pay attention to the duty handy rather than handling minute info and pointless complexity.

Making Java Groov is a realistic advisor for builders who are looking to take advantage of Groovy of their paintings with Java. It begins via introducing the main ameliorations among Java and Groovy and the way to exploit them for your virtue. Then, you'll concentrate on the events you face each day, like eating and growing RESTful net prone, operating with databases, and utilizing the Spring framework. You'll additionally discover the good Groovy instruments for construct approaches, checking out, and deployment and how you can write Groovy-based domain-specific languages that simplify Java development.

Written for builders acquainted with Java. No Groovy event required.

Purchase of the print publication encompasses a loose booklet in PDF, Kindle, and ePub codecs from Manning Publications.

Beginning Java Programming: The Object-Oriented Approach

A complete Java consultant, with samples, workouts, case reviews, and step by step instructionBeginning Java Programming: the item orientated process is a simple source for purchasing began with one of many world's so much enduringly well known programming languages. in keeping with sessions taught through the authors, the ebook starts off with the fundamentals and steadily builds into extra complex suggestions.

Cocoon 2 Programming: Web Publishing with XML and Java

Due to the tireless efforts of open-source builders, Cocoon has quick received visibility because the preeminent XML-based net publishing framework. regrettably, its documentation continues to be an important shortcoming. if you are new to Cocoon, gaining a feeling of precisely what you are able to do with it may be tricky, and really getting begun may be even tougher.

Example text

Although no Java technology fills the exact same niche as OSGi, several tread similar ground, and it’s worth understanding their relevance before moving forward. 4 Putting OSGi in context OSGi is often mentioned in the same breath with many other technologies, but it’s in a fairly unique position in the Java world. Over the years, no single technology has addressed OSGi’s exact problem space, but there have been overlaps, complements, and offshoots. Although it isn’t possible to cover how OSGi relates to every conceivable technology, we’ll address some of the most relevant in roughly chronological order.

Because the two ignored each other for so long, there are some challenges in moving existing Java EE concepts to OSGi, largely due to different assumptions about how class loading is performed. Still, progress is being made, and today OSGi plays a role in all major application servers, such as IBM’s WebSphere, Red Hat’s JBoss, Oracle’s GlassFish, ObjectWeb’s JOnAS, and Apache’s Geronimo. Download from Wow! 2 Jini An often-overlooked Java technology is Jini, which is definitely a conceptual sibling of OSGi.

Logical modularity refers to this form of code visibility. Physical modularity refers to how code is packaged and/or made available for deployment. In OSGi, these two concepts are largely conflated; a logical module is referred to as a bundle, and so is the physical module (that is, the JAR file). Even though these two concepts are nearly synonymous in OSGi, for modularity in general they aren’t, because it’s possible to have logical modularity without physical modularity or to package multiple logical modules into a single physical module.
