Standardizing Java Persistence with the EJB3 Java Persistence API Publish Date: May. 17, 2006
Dissatisfaction with entity beans as an "official" means of persisting Java objects to databases has prompted a number of "unofficial" approaches, such as the very popular Hibernate. Now EJB3 seems to have learned its lesson: its new Java Persistence API allows you to persist plain old Java objects (POJOs) with a minimum of fuss and just a few annotations. Debu Panda looks at how to put this new standard to work.
Using Dependency Injection in Java EE 5.0 Publish Date: Jan. 4, 2006
Dependency injection, also known as inversion of control, is a programming technique being adopted by many programmers and frameworks, including the popular Spring framework. But using it in J2EE 1.4 requires a burdensome deployment-descriptor-based approach. Debu Panda shows how Java EE 5.0 provides relief in the form of annotations-based dependency injection.
Constructing Services with J2EE Publish Date: May. 25, 2005
Web services are a popular means of deploying service-oriented applications, and the standards in J2EE 1.4 make it easier to develop services that are portable and interoperable. Debu Panda shows you how, and takes a look at how things will get easier in J2EE 5.0.
An Introduction to Service-Oriented Architecture from a Java Developer Perspective Publish Date: Jan. 26, 2005
Service-oriented architectures offer a new way to think about building software applications, with coarse-grained pieces of functionality split out into "services" that communicate with standardized, widely understood interfaces like XML and SOAP. In this article, Debu Panda shows you how to design and connect SOAs.
Using Timers in J2EE Applications Publish Date: Oct. 13, 2004
J2SE gained support for scheduled tasks in 1.3, and J2EE 1.4 provides an enterprise equivalent, with transactional, scheduled callbacks provided by application containers. Debu Panda introduces J2EE timers by way of an EJB that gets scheduled services.
Using a JMS Provider with MDBs via the J2EE Connector Architecture Publish Date: Jun. 23, 2004
Message-Driven Beans (MDBs) get a big boost in J2EE 1.4 via integration with the J2EE Connector Architecture (JCA), which opens up interesting possibilities to use messaging to and from legacy systems. Debu Panda shows how this can be accomplished.
