Hi Frank,
I'm very glad to hear that you are trying out some of the new JPA 2.0
features. I've found that the issue you found isn't specific to OpenJPA
2.0. This problem also exists on previous releases (1.0.2) of OpenJPA. In
short, if an entity is defined only in the orm.xml and not all fields are
defined, an exception is thrown. Annotating the class with @Entity or
defining all fields in the orm.xml corrects the problem.
This entity definition corrected the problem:
<entity class="....model.Person" name="Person" access="FIELD">
<table name="PERSON" />
<attributes>
<id name="id">
<generated-value strategy="SEQUENCE" />
</id>
<basic name="firstName"/>
<basic name="lastName"/>
<element-collection name="addresses" />
<attributes>
</entity>
Based on what I've read in the JPA spec, this looks like a bug. OpenJPA
should consider firstName and lastName persistent fields by default. I've
opened JIRA OPENJPA-859 <https://issues.apache.org/jira/browse/OPENJPA-859> for
this issue.
