Please don't laugh at my stupid question but I just want be sure about my thinking.

Since JPA can run without container, will a pure core Java API & JPA based application (without container) be considered EJB centric app?
Another words, is JPA considered integral part of EJB since it came with EJB3?

My thinking: An EJB centric app must have at least one session bean or MDB.

If it can run without an EJB container, it's not EJB-centric.

Take a look at this link:


An EJB-centric application extends the modular, component-based application described in the previous section, with two main differences. First, this design uses a front component for a controller. Second, data represented by the JavaBeans components is maintained by enterprise beans. This design provides flexibility, manageability, and separation of developer responsibilities.

Did it answer the question?

SCEA, PMP, read my blog:
