I have a class hierarchy that looks something like this:

class A is abstract
class B is a concrete class, extends A
class C is an abstract class, extends A
classes C1, C2, and C3 are concrete classes, extends C.

C1, C2, C3 have some transient data and do not have any additional data to be stored in the database.

I would like to find an annotation that maps my object hierarchy to tables A, B, C. Something like this:

class A has
<table name="A"></table>
<inheritance strategy="JOINED"/>
<discriminator-column name="type" discriminator-type="STRING" />

class B has
<table name="B"></table>
<primary-key-join-column name="id" referenced-column-name="id"/>
<discriminator-value>B</discriminator-value>

class C has
<table name="C"></table>
<inheritance strategy="SINGLE_TABLE"/>
<discriminator-column name="type" discriminator-type="STRING" />

class C1 has
<primary-key-join-column name="id" referenced-column-name="id"/>
<discriminator-value>C1</discriminator-value>

class C2 has
<primary-key-join-column name="id" referenced-column-name="id"/>
<discriminator-value>C2</discriminator-value>

Does anyone know if hibernate or JPA supports a hybrid inheritance strategy using both joined and then single_table?

Thanks for any info you have provide!

I too would like to combine @Inheritance.JOINED with @DiscriminatorColumn since I have some subclasses which have their own extra data and some which do not.
