J2EE application model on z/OS

The J2EE Application Model on z/OS® is exactly the same as on other platforms.

The J2EE Application Model on z/OS follows the SDK specification, exhibiting the following qualities:

Functional–satisfies user requirements
Reliable–performs under changing conditions
Usable–enables easy access to application functions
Efficient–uses system resources wisely
Maintainable–can be modified easily
Portable–can be moved from one environment to another.

WebSphere® Application Server on z/OS supports four major models of application design: Web-based computing, integrated enterprise computing, multithreading distributed business computing, and service-oriented computing. All these design models focus on separating the application logic from the underlying infrastructure; that is, the physical topology and explicit access to the information system are distinct from the programming model for the application.

The J2EE programming model supported by WebSphere Application Server for z/OS makes it easier to build applications for new business requirements because it separates the details from the underlying infrastructure. It provides for the deployment of the component and service-oriented programming model offered by J2EE.
