The contract between a J2EE component and its container. The contract includes life-cycle management of the component, a context interface that the instance uses to obtain various information and services from its container, and a list of
services that every container must provide for its components.

  A mechanism whereby security information needed for signing on to a resource is provided by an application component.

  A standard extension mechanism for containers that provides connectivity to enterprise information systems. A connector is
specific to an enterprise information system and consists of a resource adapter and application development tools for
enterprise information system connectivity. The resource adapter is plugged in to a container through its support for
system-level contracts defined in the Connector architecture.

  An architecture for integration of J2EE products with enterprise information systems. There are two parts to this
architecture: a resource adapter provided by an enterprise information system vendor and the J2EE product that allows this
resource adapter to plug in. This architecture defines a set of contracts that a resource adapter must support to plug in to
a J2EE product-for example, transactions, security, and resource management.

  An entity that provides life-cycle management, security, deployment, and runtime services to J2EE components. Each type of
container (EJB, Web, JSP, servlet, applet, and application client) also provides component-specific services.

  The mechanism whereby data transfer between an entity bean's variables and a resource manager is managed by the entity bean's
container.

  The mechanism whereby security information needed for signing on to a resource is supplied by the container.

  A transaction whose boundaries are defined by an EJB container. An entity bean must use container-managed transactions.What is content
