Jess in Action: Java Rule-Based Systems by Ernest Friedman-Hill

By Ernest Friedman-Hill

Jess is a principles engine with very good Java interaction. "Jess in motion" is a quick and fast learn. truly utilizing Jess is unusually tricky.

In "Jess in Action", you are going to examine the Jess syntax (facts and rules), the way it interplays with Java (scripting Java from Jess, Java Beans as shadow evidence, calling Jess from Java) and extremely vast examples with very specific backgrounds.

All for model 61p4. the present Jess model is 71p2. As an advantage one could obtain from the books web site a nonprofit model of Jess with out a closing date. regrettably: Jess isn't really open resource.

If you must do a little Jess, "Jess in motion" is a superb supplement for the web documentation.

Java 7 Concurrency Cookbook

Over 60 basic yet quite potent recipes for gaining knowledge of multithreaded software improvement with Java 7
* grasp all that Java 7 has to provide for concurrent programming
* become familiar with thread administration, the Fork/Join framework, concurrency periods and lots more and plenty extra during this e-book and ebook
* a pragmatic Cookbook jam-packed with recipes for reaching crucial Java Concurrency initiatives

In element

Java continues to be the worldwide regular for constructing a number of functions and firm software program, and the release of Java 7 brings with it fascinating new features for concurrent programming in terms of the concurrency utilities enhancement. this permits builders to utilize their functions with parallel activity functionality. "Java 7 Concurrency Cookbook" covers all parts of the Java concurrency API, supplying crucial recipes for profiting from the fascinating new capabilities.

On your desktop, you could take heed to song whenever you edit a be aware rfile and browse your emails, all of sudden! it is because your working method permits the concurrency of projects, very similar to the Java platform which deals quite a few sessions to execute concurrent initiatives inside of a Java software. "Java 7 Concurrency Cookbook" covers crucial positive aspects of the Java concurrency API, with designated emphasis at the new services of model 7.

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

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

With the step by step examples during this ebook you’ll have the ability to practice an important and worthy positive factors of the Java 7 concurrency API.

What will you study from this booklet
* grasp the fundamentals of thread administration and synchronization prior to diving into larger point concurrency projects
* familiarize yourself with interesting new concurrency good points of Java 7, together with the Phaser category and the Fork/Join Framework
* effectively delegate thread administration to executors
* customise essentially the most helpful sessions of the Java concurrency API with real-world examples
* learn how to use high-level Java utilities to regulate synchronization among threads
* Get a sneak peek at utilizing Eclipse and NetBeans for debugging concurrency code
* keep away from issues of information inconsistency by way of studying the knowledge constructions you might want to use in concurrent purposes
* benefit from an advantage appendix full of information that each programmer should still reflect on while constructing a concurrent program

Making Java Groovy


Making Java Groovy is a pragmatic guide for builders who are looking to mixture Groovy into their day by day paintings with Java. It starts off through introducing the main ameliorations among Java and Groovy—and how one can use them in your virtue. Then, it courses you step by step via reasonable improvement demanding situations, from net functions to internet companies to machine purposes, and exhibits how Groovy makes them more straightforward to place into production.

About this Book

You don't want the complete strength of Java whilst you're writing a construct script, an easy approach application, or a light-weight net app—but that's the place Groovy shines brightest. This based JVM-based dynamic language extends and simplifies Java so that you can pay attention to the duty handy rather than dealing with minute information and pointless complexity.

Making Java Groov is a realistic advisor for builders who are looking to reap the benefits of Groovy of their paintings with Java. It starts off through introducing the foremost changes among Java and Groovy and the way to take advantage of them in your virtue. Then, you'll concentrate on the events you face each day, like eating and growing RESTful internet companies, operating with databases, and utilizing the Spring framework. You'll additionally discover the good Groovy instruments for construct approaches, checking out, and deployment and the way to 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 incorporates a loose book in PDF, Kindle, and ePub codecs from Manning Publications.

4 Interface building For most rule-based systems to do any useful work, they need to be connected in some way to their environment. Sometimes this means database access; other times it means directly reading values from sensors and sending commands to embedded hardware. Before you begin to code your rules, you try to develop a picture of what your system will need to realize these connections. Depending on your development environment, your rules may already have a built-in ability to connect to all the data sources and sinks they’ll need to reach, directly from the rule language.

Rules are a lot like the if-then statements of traditional programming languages. You might write a gum-chewing rule like this, in an English-like pseudocode: IF I am in school AND I am chewing gum THEN spit out the gum END The if part of a rule written in this form is often called its left-hand side (often abbreviated LHS), predicate, or premises; and the then part is the right hand side (RHS), actions, or conclusions. The domain of a rule is the set of all information the rule could possibly work with.

The rule engine is often embedded in a network-based server so that it can be accessible across an enterprise. This enterprise-level use of a rule engine is probably the fastest growing and most visible market for rule-based systems programming today. Some application servers, like BEA’s WebLogic, include integrated rule engines. Other vendors like ILOG sell rule engines meant to be used with third-party servers. There are literally 12 CHAPTER 1 Rules to the rescue dozens of rule engines to choose from, targeted toward this product niche.
