Spring Data JPA 1.1.0 GA comes with CDI integration, new query keywords, declarative locking and a ton of bug fixes and improvements.

Want to know how much uptake Java SE 7 has seen since its release? Which IDE has grown most in user base since last year? Which application server has jumped 300% in popularity by Java developers since 2011? You’ll also get the latest numbers on Oracle WebLogic, IBM WebSphere, Eclipse, JBoss, Jenkins/Hudson, Maven, Subversion and Tomcat (alert: shameless SEO plug). It’s all in there!

In this post I’ll present you with our candidates and the criteria we are evaluating each framework with. Over the next weeks I’ll post the actual evaluation of each framework and finally what our choice is and why.

In recent times, many programming languages that run on JVM have emerged. Many of these languages support the concept of writing code in a functional style. Programmers have started realizing the benefits of functional programming and are beginning to rediscover the powerful style of this programming paradigm. The emergence of multiple languages on JVM have only helped to reignite the strong interest in this paradigm. This article shows how functional programming is different from imperative styles and the options available on JVM for writing code in a functional style.

In Simple Made Easy argues Rich Hickey that mixing orthogonal concerns introduces unnecessary complexity and that we should keep them separate. This mixing sometimes occurs on such a basic level that we believe that there is no other way to do it,

Combine BigMemory and Terracotta Server Array for Performance and Scalability exhausting hardware resources!

Lately there has been lots of noise about "Real Time" Big Data. Lots of companies that associate themselves with this term are generally in analytical space and to them it really means "low-latency" for analytical processing of data which is usually stored in some warehouse.

Just a quick note that Part One of the Using Properties and Bindings in JavaFX 2 article that I wrote for Java Magazine is now available. It is written in tutorial-style, and contains a download that has exercise/solution code. Here's a video that introduces the article.

An attempt to explain Java logging frameworks with a conceptual model for logging. Turns out its quiet hard to explain in a succinct way.

Every time I had to build such an app I struggled with passing options via command line parameters. Instead of concentrating on implementing logic, I had to create a parser, validator and so on. And in another console application I had to do the same… again and again. But thankfully it’s over. Thanks to small library by Cédric Beust, creator of well-known Java testing framework TestNG. This time he created JCommander with a motto "Because life is too short to parse command line parameters".

"A component must not execute more than 20 SQL statements". A relative new discipline to enforce these types of architectural rules is Dynamic Architectural Validation. We wrote a chapter on the best practices and show how to repurpose your existing unit and functional tests. This allows you to identify architectural regressions that have been introduced with code changes by comparing the dynamic behavior between test runs.

This section in the Painless TDD series looks at object dependencies; when you ask for more than you need, and why the "natural" choices may not always be the best ones.

Even Oracle might not have known what it had when it brought Google to trial, but when the trial began to turn around the idea of copyrighting APIs, it couldn't have gone better for an old-school enterprise software company with a lot to lose if the cloud and open source continue to take over IT.

I wanted to explore learning to use MongoDB with Java and the best way to do this was to develop a toy application. And to add to this, I thought of using JavaFX and building a desktop

A tutorial on the definition and benefits of encapsulation in Java.

Quick survival guide for Safari and WebSockets.

Kirk Knoernschild is one of the leading experts when it comes to the OSGi community. DZone recently had a chance ot interview him about his thoughts on modularity in 2012 and his new book is "Java Application Architecture: Modularity Patterns with Examples Using OSGi." The book introduces 18 patterns that will help you design more modular software.

Lately there has been lots of noise about "Real Time" Big Data. Lots of companies that associate themselves with this term are generally in analytical space and to them it really means "low-latency" for analytical processing of data which is usually stored in some warehouse, like Hadoop Distributed File System (HDFS).

We are happy to announce the release of Drools (Expert, Fusion, Planner, Guvnor) 5.4.0.Final. jBPM 5.3.0 announcement will follow shortly and the link will be added when it does.

This blog demonstrates how simple Server Side Events can be added to any Servlet based application via the Atmosphere Framework.

The previous tutorial covered basic XML processing in Scala, but as I noted, XML is not the primary choice for data serialization these days. Instead, JSON (JavaScript Object Notation) is more widely used for data interchange, in part because it is less verbose and better captures the core data structures (such as lists and maps) that are used in defining many objects. It was originally designed for working with JavaScript, but turned out to be quite effective as a language neutral format. A very nice feature of it is that it is straightforward to translate objects as defined in languages like Java and Scala into JSON and back again, as I’ll show in this tutorial. If the class definitions and the JSON structures are appropriately aligned, this transformation turns out to be entirely trivial to do — given a suitable JSON processing library.

DocRaptor is an HTML to PDF API that uses Prince XML to create PDF files from HTML. DocRaptor has better CSS support and produces higher quality documents than comparable applications. DocRaptor is easy to integrate into your own web application to quickly generate great looking PDF files.

Developers are now being tasked with writing applications for the cloud. Although that is a simple buzzword, what does it mean to me, the developer? When developing Java Enterprise applications targeted for cloud deployment, what configuration or code changes do I need to be aware of? Will Java EE 7 make it easier? Whether you are using pure JEE or the Spring Framework, can we simply deploy our enterprise applications in the cloud? This session will give an overview of why the cloud is gaining momentum, what are the key facets that one needs to understand to deploy enterprise applications in the cloud. We will look at the differences between CloudFoundry, CloudBees, Heroku and Amazon Beanstalk. Including a demonstration of configuring an existing application and deploying it to the cloud.

There doesn’t seem to be a day that goes by without another development in the entire Java ecosystem in regards to Cloud. In this issue of Java Tech Journal, we attempt to distill the noise down for you - by looking at some of the most popular PaaS options. Articles featuring Cloud Foundry, OpenShift, Cumulogic, CloudBees and a general overview of which PaaS is best for you
