10 years ago, when we were decided to use Java technology to create a new application,
for use at Amway Corp; we thought it was sufficient to say, "We are using Java!".
We were wrong...
We quickly realized that there was Java 2 Standard Edition and there was Java 2 Enterprise Edition.
Since we were architecting our application to run in an application server-based environment,
we concluded that...
The search algorithm is used for finding an item within a collection of items. String searching algorithm is a category of the search algorithm. The main idea of string searching algorithm is to find text pattern in a string. There are many techniques used to solve this. This second entry will be about 'Knuth-Morris-Pratt (KMP)' algorithm and how you can apply it on a simple Java code.
Hello all. My name is Larry Fernandez and I am a Principal Software Developer in IT.
I work for Amway Corp in Grand Rapids, Michigan.
March 2012 was my company's 10-year anniversary using Java. We have over 1 million lines of J2EE code in production,
with more on the way. I have been here since our "Java" beginnings and I have played many roles
(developer, architect, project manager, etc.).
We...

A couple weeks ago I figured out (more or less) what's wrong with Java threads. It's not that there's anything so wrong with Java threads per se -- it's just that they were designed to meet a need that is different from what developers face today: a world full of multicore processors...
A few nights ago, I was browsing the chapters about concurrent programming in Herbert Schildt's excellent "Java: The Complete Reference, 8th Edition," and I was struck by the evolution of concurrency in Java over the years, from threads, through the richness of Java 5's Concurrency Utilities, and on to Java 7's Fork/Join Framework...
Release the newest version of the framework to persist objects in Apache Cassandra in easy way. Among improvement is the JPA annotations, also JPQL.
JCassandra jCassandra=persistence.createJCassandra("select * from Person"); List<Person> persons=jCassandra.getResultList();
table 1: sample using JPQL in Easy-Cassandra
Easy-Cassandra 1.0.8
Easy-Cassandra 1.0...
In some earlier posts, I've talked about Java threads, Java Thread Overhead, and Amdahl's Law and Parallel Processing Speed-Up. My next investigation in this series is Java 7's new Fork/Join Framework. I plan to spend quite a lot of time in this particular investigation...
With the advent of multicore processors on everything from desktop computers to tablets, pads, and even mobile phones, parallel processing is gaining increasing attention. This is at least in part what's behind the release of the Fork/Join Framework in Java 7, and the inclusion of Lambda Expressions...

Fast Messenger in JavaScript can forward messages for your objects and functions within the main UI thread, one or multiple web workers, or even between UI thread and web workers. This way your JavaScript programs are promoted to be multi-threaded in no time.
FM Lite is a specially tailored subset of FM that aims to complete with threads and multithreading.
Fast Messenger provides FutureReply a mechanism similar to the Future in Java. Sequential OO programs may keep the same program flow while enjoying high concurrency out of asynchronous messaging. When you obtain an instance of FutureReply by sending out a message, your code will continue without blocking. You can perform any work before you decide to check whether a reply is ready. Even the checking offers you two options, you can check, leave (non-blocking) and come back later, or you can wait (blocking) until a reply is ready.
This post revisits the active object implementation of the quick sort example, and introduces basic concepts of active object model provided by Fast Messenger. In the post I will explain what active objects are, how they identify themselves, how they address each other, and how they communicate with codes found in the quick sort example. (This post will not cover features not found in the example.)
This post describes two concurrent implementations of quick sort algorithm. One version uses active objects (provided by Fast Messenger) for concurrence, while the other version uses traditional multithreading.
Glassfish
The following blog shows an example of Server Sent Events in HTML5. It demonstrates using a sample where a server periodically polls for Twitter information and sends the data to the clients using Server Sent Events
Server-Sent Events (SSE) support in GlassFish
This blogs lists the tips, tricks and solutions to most commonly faced issues while using Embedded GlassFish.
This blog describes how to configure maven-embedded-glasssfish-plugin to be able to deploy more than one application.

Hello there! I'm Alessandro Gentile and this is my brand new blog on java.net.
I must say, I'm honored to be part of this community. Two months ago I joined the GlassFish project and I began to write tutorials. There are several reasons for my choice and among them there's the love for open source software and java EE.
Markus Eisele in his blog two weeks ago wrote an article that I found truly...

Introduction
In my previous blog post, I have asked to many of you this question: "What JSF should become?". And since then, I was quite silent. The reason behind it, is that I was working to build a concrete implementation of this vision and today I'm glad to give you a concrete demonstration of it. So Ladies and Gentlemen, why...
