Well. The application setup on Geronimo is just like any other, also
requiring an ejb-jar.xml. Though there is one difference, you need the
deployment descriptor. This would be in the jar under

So just take any EJB jar, and add META-INF/openejb-jar.xml

Minimally it can contain:
<?xml version="1.0" encoding="UTF-8"?>
<openejb-jar xmlns=""

Definitely. You get used to it's way very quickly. I must admin that
Glassfish, which I've worked with more, is much more mature on the
"intuitive" front, requiring very little knowledge of the server in
order to get started. Geronimo is getting there. Though the extra
effort is worth it. The performance gains on the EJB front alone makes
me never want to turn away. Too bad Geronimo hasn't been pitted
against the apparently "fastest appserver, Glassfish". Geronimo is
also very flexible, so the better you get to know it, the more you
will be able to do with it.
