OpenEJB has been around for seven years and is one of the few standalone and embeddable EJB containers. Useful mainly for unit testing EJB beans (embedding the containers in unit tests), OpenEJB is also available as a Tomcat plug-in. Which means you can call EJB beans from your Web application's servlets. This fact alone opens up new possibilities for migrating current Web applications to JEE 5 in addition to facilitating development and testing using the popular Apache Tomcat server instead of a full JEE application server, even if you eventually deploy to a dedicated JEE application server. OpenEJB 3 supports JPA out-of-the-box (and CMP by mapping to JPA) and uses the Apache OpenJPA implementation. JMS support is also included in ActiveMQ and recently Web Services annotation support has been added to hook up with a Web service provider like Axis2. There's built-in database support via hsqldb but it's easy to configure any database server via the conf/openejb.xml configuration file.
OpenEJB was started by David Blevins and Richard Monson-Haefel and initially supported EJB 1.1 and part of the EJB 2 specification. In 2006 OpenEJB 1.0 was released completing this initial 0.9.2 "branch," while work continued on the EJB 3 version targeting EJB 3. A couple of the OpenEJB 1.0 features became casualties as a result of changes required to support the move from Geronimo 1.0 to 2.0 (the OpenEJB 2.0 internal equivalent), so the team went back to the add embeddability as well as Tomcat plugability recently, upgrading the 1.0 release to a OpenEJB 3.0 beta release while graduating from Apache incubation. Despite the beta status, the OpenEJB 3 container is certified via Geronimo 2.0's JEE 5 certification back in June, making it usable in production environments as a standalone server. What's new and what I'll go into detail here is the Tomcat plug-in. Currently OpenEJB 3.0 supports only Tomcat 6.x but support for Tomcat 5.5 is being added.

Even as cloud and managed services grow increasingly central to business strategy and performance, challenges remain. The biggest sticking point for companies seeking to capitalize on the cloud is data security. Keeping data safe is an issue in any computing environment, and it has been a focus since the earliest days of the cloud revolution. Understandably so: a lot can go wrong when you allow valuable information to live outside the firewall. Recent revelations about government snooping, along with a steady stream of well-publicized data breaches, only add to the uncertainty

In the consumer IoT, everything is new, and the IT world of bits and bytes holds sway. But industrial and commercial realms encompass operational technology (OT) that has been around for 25 or 50 years. This grittier, pre-IP, more hands-on world has much to gain from Industrial IoT (IIoT) applications and principles. But adding sensors and wireless connectivity won’t work in environments that demand unwavering reliability and performance. In his session at @ThingsExpo, Ron Sege, CEO of Echelon, will discuss how as enterprise IT embraces other IoT-related technology trends, enterprises with i...

The Internet of Things (IoT) is causing data centers to become radically decentralized and atomized within a new paradigm known as “fog computing.” To support IoT applications, such as connected cars and smart grids, data centers' core functions will be decentralized out to the network's edges and endpoints (aka “fogs”). As this trend takes hold, Big Data analytics platforms will focus on high-volume log analysis (aka “logs”) and rely heavily on cognitive-computing algorithms (aka “cogs”) to make sense of it all.
