Hello experts,
I'm new in using eclipselink and would like to run it in a Spring DM
environment.
I would like to have a modular application structure, which could be
extended by just adding additional bundles. So I tried to use fragments,
which are providing additional xml-mappings to enable additional entities.
My project bundles structure looks lite this:
* core.domain
- bundle exporting some abstract and tooling classes
* core.persistence
- bundle wich uses spring dm to instantiate the
EclipseLinkJpaVendorAdapter and LocalContainerEntityManagerFactoryBean
to create a EntityManagerFactory for all components
* component_a.domain
- bundle exporting domain-classes of component_a
* component_a.persistence
- fragment with eclipselink-orm.xml for defining entities of
component_a - depends on component_a.domain
- host is core.persistence
- depends on component_a.domain
* component_b.domain
- similar to component_a.domain
* component_b.persistence
- similar to component_a.persistence
Can I define in the persistence.xml (placed in core.persistence) that
every eclipselink-orm.xml from the multiple fragments have to be loaded?
Using only component_a with eclipselink-orm.xml and persistence.xml in
it, this is working.
Using component_a and component_b together the mapping of component_a is
not loaded.
regards,
Lars

Have you found a solution to your problem? I just ran into a similar
problem, when a spread my entities over several model-bundles.
