I wonder this topic. Is using EJB containars in desktop application

great technology and using it with stand alone application can be
interesting and give us a great possibilities.

Having a desktop app making calls to EJB running on a server
is seen - not quite as popular as a web interfaces, but seen
occasionally.

You can not run a desktop GUI (Swing or SWT) inside an
EJB container, so you need both a client app and a server.
The server could run on the client PC, but I doubt that will
make sense in most cases.

Nothing in the EJB specification forbids an EJB container from running
inside a GUI app -- however, the EJBs themselves are not permitted to
create or manipulate GUI elements (except possibly indirectly via
callbacks). However, I'm not aware of any EJB containers designed for
embedding inside other apps; most people who want something like that
seem to be settling on Spring instead, as it imposes far fewer
requirements.
