Hi together,
I decided that it would be a valuable way to migrate existing
CMP2.1 EJBs to OpenJPA, as this should also work
OUTSIDE a Java EE 5 (and therefore inside EJB2.1) container. The
problem I see is that I have to provide the OpenJPA
mappings as Java5 annotations, and EJB2.1 projects are bound to
Java 1.4 – without having annotations.
run geronimo under jdk 1.5. This will work unless you are using
corba. The almost released 1.2 might work if you are using corba.
Is there a way of providing the mapping via XML-descriptor too?
yes, as per jpa spec.
Does anybody see other possible failures when running OpenJPA
within a Java EE 1.4 container?
I'm not sure why you don't want to use annotations. You should use
the geronimo 1.2 not-quite-released version which includes jpa and in
particular openjpa support. I converted the daytrader performance
test app to use jpa and it works fine. In particular you can use
container managed entity managers/persistence contexts rather than
app managed ones. You might like to take a look at daytrader trunk,
it has all the annotations and a jpa plan. You do need to run
geronimo under jdk 1.5 for this to work.
