3.2.6. Infrastructure Interfaces
Infrastructure interfaces provide access to frequently used functionality of the platform. Most of them are located in the global module and can be used both on the middle and client tiers. However, some of them (Persistence, for example) are accessible only for Middleware code.
Infrastructure interfaces are implemented by Spring Framework beans, so they can be injected into any other managed components (managed beans, Middleware services, generic user interface screen controllers).
Also, like any other beans, infrastructure interfaces can be obtained using static methods of
AppBeans class, and can be used in non-managed components (POJO, helper classes etc.).
