TSS Announces Portability Re-Launch on WebLogic and Oracle9iAS

TheServerSide has demonstrated J2EE portability in action by re-launching itself on a cluster of J2EE application servers, consisting of Oracle9iAS, and BEA WebLogic. The launch itself was an involved process, and we've written an article about various issues that had to be resolved when migrating TSS to a clustered environment.

TheServerSide as an application now stands as a great example of J2EE portability in action. It's a production system with heavy loads (over 2 million pageviews/month) that runs with the same J2EE application binaries deployed across different vendors servers. Each server is J2EE 1.3 compliant and runs TSS in a consistent fashion.

Monson-Haefel's Guide to Enterprise JavaBeans - EJB 2.1: The Timer Service

By Richard Monson-Haefel

The Timer Service is a facility of the EJB container system that provides a timed-event API, which can be used to schedule timers for specified dates, periods, and intervals. A timer is associated with the enterprise bean that set it, and calls that bean's ejbTimedout() method when it goes off. This installment describes the EJB Timer Service API, its use with entity, stateless session, and message-driven beans, and provides some criticism and suggested improvements of the Timer Service.

New Tech Talks

Get leading edge information on J2EE from those who know it best, in TheServerSide's Tech Talks! Videos Hosted on HostJ2EE.com. Featured this week is Jishnu Mitra who talks about EJB 2.1 and Web Services

Jishnu Mitra - J2EE Architect, Borland

In this interview, Jishnu talks about the new features in EJB 2.1, including the timer mechanism, the transition from EJB 2.0 to 2.1, and discusses the future of EJB. He discusses the challenges of EJB and Web services integration, and also looks at J2EE clustering and application server partitioning.

Enterprise Java Education Strategies

Learn all about J2EE Patterns

Recently we announced an exciting new training course called "J2EE Patterns". This course is useful for increasing your value in today's economy, and to help make J2EE projects succeed.

We recently held this course for the first time, and wrote up a day-by-day series of articles that describe what it's like to be in the course. These free articles are now available for download. They will teach you about J2EE Patterns, and are also good for describing what it might be like to participate in a J2EE Patterns course.

New Patterns

View Relationships

By G Day

Container managed relationships are problematic with CMP 2. If you require processing, or filtering on the data, each data row is required to be instantiated as an entity bean. This technique allows simple object representation of the data row at an entity bean level, allowing complex processing, filtering etc, and instantiation of entity beans if required.
Read more on this pattern .

Entity Strategy

By Fusayuki Minamoto

This pattern allows an entity bean to call methods provided by a data transfer object (DTO). This decouples the entity from the behavior. The persistent data is provided by an entity bean and the behavior by a DTO.
Read more on this pattern .

Access Transfer Object

By Robert Boothby

This patterns is intended to address the design and performance issues around access to large datasets from an underlying store where communications performance is an issue. Primarily envisaged for EJB 1.1 and CORBA distributed component environments.
