Chapter EJB.18. Runtime Environment

This chapter defines the application programming interfaces (APIs) that a compliant EJB container must make available to the enterprise bean instances at runtime. These APIs can be used by portable enterprise beans because the APIs are guaranteed to be available in all EJB containers.

The chapter also defines the restrictions that the EJB container provider can impose on the functionality that it provides to the enterprise beans. These restrictions are necessary to enforce security and to allow the container to properly manage the runtime environment.
