Hi
I thought it needed to be created through a factory, also I have some
properties that need to be set, I now do like this,
Now I got EntityManagerFactory =
Persistence.createEntityManagerFactory("Pesistent", props);
can I do that something like this when using jndi,
<Resource>..
<type>org.apache.openjpa.persistence.OpenJPAEntityManagerFactory</type>
<properties key="" value="">
</Resource>
Sorry for all the questions, but Im new to this
