J2EE Container Services

The interface between the low-level platform-specific functionality and a component is J2EE container. Any kind of component can be executed and assembled in Java EE module and deployed on its container.

The process of assembly involves specifying container settings for every component in the Java EE application. Container settings customize the support provided by the Java EE server, such services as security, Java Naming and Directory Interface (JNDI) API lookups, transaction management, and remote connectivity.

The Java EE security model is a configuration for web component or even enterprise bean which allows only authorized users to access the resources.

The Java EE transaction defines relationships through the methods that composes single transaction so that all methods in one transaction are treated as a one single unit.

JNDI lookup services is the one which allows software client to look-up and discover resources in the form of Java objects by name.
