-----------------------------------------------------------------
Talking to myself it seems.... :-)
I've successfully implemented the workaround as described in my prior comment.
The isMappingMode(ClassMetaData) method of my serializer now looks like this:
[code]
@Override
public boolean isMappingMode(final ClassMetaData meta) {
return
this.isMappingMode() &&
(meta.getSourceMode() & MetaDataModes.MODE_MAPPING) != 0 &&
(meta.getEmbeddingMetaData() == null ||
this.isMappingMode(meta.getEmbeddingMetaData()));
}
[/code]

> Key: OPENJPA-1360
> URL: https://issues.apache.org/jira/browse/OPENJPA-1360
> Project: OpenJPA
> Issue Type: Bug
> Components: tooling
> Affects Versions: 1.3.0, 2.0.0
> Reporter: Laird Nelson
>
> In my ReverseCustomizer, I call classMapping.setEmbedded(true). This is
> because for a variety of reasons I need the code that is generated by the
> ReverseMappingTool to be @MappedSuperclasses, not @Entities.
> Indeed when I do this, the resulting class is a @MappedSuperclass (great!)
> BUT all of the length and nullable and other @Column attributes are missing.
> In other words, all simple fields receive only a @Basic annotation, with no
> attributes, and nothing else. In addition, the class declaration receives a
> @Table annotation with no attributes. (I'm using the command line flag that
> instructs the ReverseMappingTool to generate annotations.)
> Ideally I'd like the generated source code to look identical to the source
> code that would be generated for a ClassMapping where setEmbedded(true) was
> never called, except of course that I want the @Entity annotation to be
> replaced with @MappedSuperclass.
> Obviously if there is a better way from within a ReverseCustomizer for me to
> accomplish my (very odd) goals (mandated by a strange development process and
> a 30-year-old database), I am all ears.
