System and method for dynamically securing dynamic-multi-sourced persisted EJBS

摘要

Dynamic Multi-sourced Persisted Enterprise Java Bean (EJB) instances are dynamically created on a J2EE compliant Application Server to access data contained in multiple data source systems. This Dynamic Multi-sourced Persisted EJB is a general class responsible for dynamically aggregating source system information and securing it based on a Context definition. Individual EJB attributes that include mapping, caching and security definitions are mapped to individual pieces of data in source systems by the Context definition. A Context definition can be reloaded during execution as desired. Applications can access the Dynamic Multi-sourced Persisted EJB directly, or use a Session EJB to create a static interface to the dynamically mapped, cached and secured data. Using an attribute securing element, a security engine enforces access requirements on a system-wide basis.
