12 Best Practices for J2EE Developers Named

12 Best Practices for J2EE Developers Named

Kyle Brown and Keys Botzum, from IBM Software Services for WebSphere, together with Ruth Willenborg, Senior Manager, IBM WebSphere Performance, set out to come up with the list of what they consider to be the Top Twelve Best Practices for anyone involved in J2EE application development.

For the full details of each one, see their paper on the subject. WJ News Desk bring you here the overall summary list though, which reads as follows:

  1. Always use MVC.
  2. Apply automated unit tests and test harnesses at every layer.
  3. Develop to the specifications, not the application server.
  4. Plan for using J2EE security from Day One.
  5. Build what you know.
  6. Always use Session Facades whenever you use EJB components.
  7. Use stateless session beans instead of stateful session beans.
  8. Use container-managed transactions.
  9. Prefer JSPs as your first choice of presentation technology.
  10. When using HttpSessions, store only as much state as you need for the current business transaction and no more.
  11. In WebSphere, turn on dynamic caching and use the WebSphere servlet caching mechanism.
  12. Prefer CMP Entity beans as a first-pass solution for O/R mapping due to the programmer productivity benefits.

The motivation for compiling the list, say the authors, was paradoxically not a lack of material on the subject, but rather the opposite.

"There now are probably 10 or more books, along with dozens of articles that provide insight into how J2EE applications should be written," they state, adding: 

"In fact, there are so many resources, often with contradictory recommendations, navigating the maze has become an obstacle to adopting J2EE itself."

Brown, Botzum, and Willenborg say that they hope their efforts may assist with finding the best way through that maze.

A coldfusion front end would be easier and more cost effective to implement than jsp

I wouldn''t go around bashing Netegrity SiteMinder. It''s a far better security product than anything IBM ever launched.

I would not publish these practices. This is a really bad move that creates myths. Though the importance for the automated regression tests is an invariant for EVERY software development, not only for J2EE, others so called "best practices" are very questionable and vary from app to app.

For instance, MVC implementation caused a wide spread usage of Singletons... And the Singleton pattern is not very good OO pattern at all, it violates lots of OO principles.

The JSP usage is a very short sighted too (consider voice or handhelds web applications).

Now, I envision that IT managers and companies that make the "interview test software" will incorporate these "12 best J2EE practices" into their arsenal and we, developers, will be forced to repeat them and finally, who knows start thinking that these practices are true....

Enterprises have taken advantage of IoT to achieve important revenue and cost advantages. What is less apparent is how incumbent enterprises operating at scale have, following success with IoT, built analytic, operations management and software development capabilities - ranging from autonomous vehicles to manageable robotics installations. They have embraced these capabilities as if they were Silicon Valley startups.
The standardization of container runtimes and images has sparked the creation of an almost overwhelming number of new open source projects that build on and otherwise work with these specifications. Of course, there's Kubernetes, which orchestrates and manages collections of containers. It was one of the first and best-known examples of projects that make containers truly useful for production use. However, more recently, the container ecosystem has truly exploded. A service mesh like Istio addr...
Poor data quality and analytics drive down business value. In fact, Gartner estimated that the average financial impact of poor data quality on organizations is $9.7 million per year. But bad data is much more than a cost center. By eroding trust in information, analytics and the business decisions based on these, it is a serious impediment to digital transformation.
Predicting the future has never been more challenging - not because of the lack of data but because of the flood of ungoverned and risk laden information. Microsoft states that 2.5 exabytes of data are created every day. Expectations and reliance on data are being pushed to the limits, as demands around hybrid options continue to grow.
Business professionals no longer wonder if they'll migrate to the cloud; it's now a matter of when. The cloud environment has proved to be a major force in transitioning to an agile business model that enables quick decisions and fast implementation that solidify customer relationships. And when the cloud is combined with the power of cognitive computing, it drives innovation and transformation that achieves astounding competitive advantage.
As IoT continues to increase momentum, so does the associated risk. Secure Device Lifecycle Management (DLM) is ranked as one of the most important technology areas of IoT. Driving this trend is the realization that secure support for IoT devices provides companies the ability to deliver high-quality, reliable, secure offerings faster, create new revenue streams, and reduce support costs, all while building a competitive advantage in their markets. In this session, we will use customer use cases...
Digital Transformation: Preparing Cloud & IoT Security for the Age of Artificial Intelligence.

The IoT Will Grow: In what might be the most obvious prediction of the decade, the IoT will continue to expand next year, with more and more devices coming online every single day. What isn’t so obvious about this prediction: where that growth will occur. The retail, healthcare, and industrial/supply chain industries will likely see the greatest growth. Forrester Research has predicted the IoT will become “the backbone” of customer value as it continues to grow. It is no surprise that retail is ...
