3.3 Secure Interoperability between ORBs
J2EE applications are required to use RMI-IIOP when accessing EJB components. This allows enterprise beans to be portable between container implementations.
A J2EE container provides the runtime support for the J2EE components. A J2EE container vendor enables access to the enterprise beans via IIOP. This facilitates interoperability between containers by using the Common Secure Interoperability (CSI) protocol. Security is enabled and enforced by the ORBs, ensuring authenticity, confidentiality, and integrity. Version 2 of this protocol specification (CSIv2) is the accepted industry standard and is mandated by the J2EE specification.
