SCA EJB Component Model

The SCA Java EJB Client and Implementation specification describes how EJBs and EJB modules can be used within an SCA composition. The usage is defined at two levels:

• It is possible to use complete EJB modules as if they are SCA composites, without changing their internal details, using SCA to wire to services offered by EJBs in the module and wiring from unsatisifed EJB-refs of the module to services provided by components outside the EJB module.
• It is possible to use individual EJBs with SCA providing all the wiring
