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....

Most DevOps journeys involve several phases of maturity. Research shows that the inflection point where organizations begin to see maximum value is when they implement tight integration deploying their code to their infrastructure. Success at this level is the last barrier to at-will deployment. Storage, for instance, is more capable than where we read and write data. In his session at @DevOpsSummit at 20th Cloud Expo, Josh Atwell, a Developer Advocate for NetApp, will discuss the role and value...
DevOpsSummit New York 2018, colocated with CloudEXPO | DXWorldEXPO New York 2018 will be held November 11-13, 2018, in New York City. Digital Transformation (DX) is a major focus with the introduction of DXWorldEXPO within the program. Successful transformation requires a laser focus on being data-driven and on using all the tools available that enable transformation if they plan to survive over the long term.

Consumer-driven contracts are an essential part of a mature microservice testing portfolio enabling independent service deployments. In this presentation we'll provide an overview of the tools, patterns and pain points we've seen when implementing contract testing in large development organizations.
Adding public cloud resources to an existing application can be a daunting process. The tools that you currently use to manage the software and hardware outside the cloud aren’t always the best tools to efficiently grow into the cloud. All of the major configuration management tools have cloud orchestration plugins that can be leveraged, but there are also cloud-native tools that can dramatically improve the efficiency of managing your application lifecycle. In his session at 18th Cloud Expo, ...
Using new techniques of information modeling, indexing, and processing, new cloud-based systems can support cloud-based workloads previously not possible for high-throughput insurance, banking, and case-based applications. In his session at 18th Cloud Expo, John Newton, CTO, Founder and Chairman of Alfresco, described how to scale cloud-based content management repositories to store, manage, and retrieve billions of documents and related information with fast and linear scalability. He addresse...
Containers and Kubernetes allow for code portability across on-premise VMs, bare metal, or multiple cloud provider environments. Yet, despite this portability promise, developers may include configuration and application definitions that constrain or even eliminate application portability. In this session we'll describe best practices for "configuration as code" in a Kubernetes environment. We will demonstrate how a properly constructed containerized app can be deployed to both Amazon and Azure ...
