Enterprise JavaBeans

This is the first time that any specific information about the Enterprise JavaBean (EJB) has been given in the Your First Cup: An Introduction to the Java EE Platform source text.

If you have followed this UMLTM Parsing Analysis demonstration trail from the beginning you may recall that the analysis model - as driven strictly by the Your First Cup: An Introduction to the Java EE Platform source text - did not converge well around the 'business component' and 'business logic' concepts, which part of the analysis model to date is reproduced in all its glory (or should I say gory detail) below the «wrapper» Component for this source text sentence about EJBs, not only as a demonstration of the incredible power of the UMLTM Parsing Analysis recipe in handling complex and/or confusing and/or contradictory documentation, but also because business logic is so very vital to this demonstration, especially as these analysis «wrapper» Components are to be bound to reverse-engineered "designed" Java EE Classes and Interfaces, as we work deeper into the First Cup demonstration.

Is the EJB the rescue ? Is it in fact simply the 'business component' that was modelled as *Component_business ?

For now it will be tentatively assumed that the EJB is indeed "substitutable" for it. However then it is no longer clear that a Java EE *Server aggregates *Component_business, as indicated by the analyst's "challenge" «wrapper» Component. To resolve this more examples of the use of EJBs are needed from the Your First Cup: An Introduction to the Java EE Platform source text.
