Hi, I'm new to OpenJPA (and JPA) and trying to create the entity-mapping
XML files (classes are unannotated POJOs) for a simple parent-child
database relationship[1] (parent is department, child is employees
working at that department) Right now, here's what I have for the
mapping files:[2] (classes are here: [3]).

While my TestClass[4] (which accesses just the department table right
now) runs fine I'm getting this warning message while running it:
"2213 CompanyPU WARN  [main] openjpa.Runtime - Fields "employees" are
not a default persistent type, and do not have any annotations
indicating their persistence strategy. They will be treated as
non-persistent. If you intended for these fields to be persistent, be
sure to annotate them appropriately. Otherwise annotate them with
@Transient."

Google is returning many examples of others with this error, but I'm
still not sure what I'm doing wrong. In the department.orm.xml, I can't
map "employees" as Transient because it is already mapped as
<one-to-many/>, which is AFAICT the right mapping to do. Basically, what
do I have to fix my department.orm.xml[2] (or Department.java class[3])
in order to get rid of the above warning message?

Thanks,
Glen
