Method and system for dynamically generating enterprise java beans during installation of a service component architecture application

摘要

A method of dynamically generating stateless session beans (EJBs) during installation of a Service Component Architecture (SCA) composite to expose simple SCA POJO components to Java EE callers. During SCA composite installation, an installation utility receives an installation request for a SCA composite with a simple POJO service. If EJB service binding is defined, the installation utility collects data from a service interface to generate a corresponding bean interface and implementation classes. Generic EJB home, bean and interface class templates are pre-defined using EMF JET templates. Data collected from the service interface is fed into pre-defined EMF JET Templates to generate service-specific EJB classes. The installation utility also matches the java interface to the EJB interface to ensure compatibility. Generated bean method has code snippets to delegate calls to SCA components during runtime. Given a simple SCA POJO Service, the installation utility generates Stateless Session bean without Java EE tooling.
