i searched the forums and the docs but could not find the answer to my question. setup is
jboss as 4.0.5 GA, seam 1.2.1GA, mysql 5.1, mysql connector 5.0.6, eclipse europa.
i have a seam-gen genereted app with EJBs reverse engineered through hibernate. the EJBs
all use annotations and are connected to the db via a jndi datasource (as far as i
understand). the datasource is defined in app-dev-ds.xml, then the jndi is referenced in
persistence-dev.xml to get an EntityManagerFactory which is finally used in
componments.xml:
| <core:managed-persistence-context name="entityManager"
| auto-create="true"
|
persistence-unit-jndi-name="java:/appEntityManagerFactory"/>
|
this setup is autogenerated and works nicely. the EJBs are all bound to the corresponding
database tables.
now i'd like to bring in a new EJB to access a different table in another database. so
i duplicated the configuration: added a second datasource in persistence-dev.xml, a second
entry in persistence-dev.xml and created a second managed-persistence-context in
components.xml. that works fine and i see in the log output that the new
managed-persistence-context is created. after that my problem occurs.
after succesfully binding the EJBs to entityManager1 the JPA tries to (re)bind all EJBs to
entityManager2 which is of course not possible since it ties into another database table.
so i guess i have to exlicitly configure every EJB for a specific entityManager (1 or 2)?
but where should i do that? i tried to use
@PersistenceContext(unitName="entityManager1") in the EJBs but that did not
work.
i have some experience with spring and hibernate but i feel that i need better knowhow on
the jboss-seam ejb hibernate integration to work that question out. so thx in advance for
any advice.
