Hi Hans,
I know it is not easy to migrate this kind of business application like
small sample application given below. We would be love to help you to
get going with Geronimo.
This is a small sample with both a CMP and CMRs but it is for J2EE 1.4
and G 1.1.

Also you might able to get more information from the Daydarader sample
application because it is fairly big application compared to the sample
given above.
Hope this help you to get starting ;-) .
Thanks,
Lasantha Ranaweera

hi together,
I have been working with the JOnAS Java 2 EE application server for
about 5 years now, meanwhile
I have several projects, one of them is rather big already, it
contains about 60-70 EJB’s, two thirds
of them are CMP/CMR’ed entity beans, the rest stateless session beans.
I am thinking about migrating these projects to Geronimo for some
months now, and I decided to
wait for the first Java EE 5 release of Geronimo (Geronimo 2) – as it
will be released within the
near future I would be interested in which migration strategies you
could suggest?
I think the most problematic part will be to migrate the ca. 50 CMP
entity beans, there are a lot
of EJB-QL finders and all of those beans are inter-related with CMR.
Currently I’m thinking of doing a “soft” migration, i.e. migrating 1
by 1 of those EB’s within the
currenty architecture from CMP to hibernate, and after that performing
the move to Geronimo (which will
mean that then only the session beans will have to be migrated which
should be less problematic).
what do you think about that?
Anybody already migrated large CMP/CMR apps to Geronimo?
regards,
Hans
