Then you probably have a classpath/packaging issue. The OpenJPA error
contains a nested class name (see $ in the name):
com.werner.accounting.model.PeoplesoftSegmentEntity$PeoplesoftSegmentId.

no, it's a top level class.
I also tried static nested class. Still the same issue I met.

Is PeoplesoftSegmentId an *inner* (i.e. non-static nested) class? Make
it a static nested class or a top level class and try.

I got the same exception.
nested exception is: <0|false|0.9.7>

ID Class is:
public class PeoplesoftSegmentId implements Serializable {
public String _businessUnit;
public String _vasTourId;
/** Creates a new instance of PeoplesoftSegmentId */
public PeoplesoftSegmentId() {
}
@Override
public int hashCode() {
int hash = 0;
hash += (this._businessUnit != null ?
this._businessUnit.hashCode() : 0);
hash += (this._vasTourId != null ? this._vasTourId.hashCode() :

Entity Class is:

Are you using @Id or @IdClass or @EmbeddedId annotations?
I'm looking at 2.1.4, 9.1.14, and 9.1.15 and trying to figure out
which case you're having trouble with.

Hi Jeff,
It would be useful if you could include a code fragment and the @Id
annotation for your class to diagnose this.

getting this error:

this error doesn't seem to correspond to any of the requirements
of an ID class as defined in the spec.
my first guess is that it wants me to add an constructor that
takes the result of toString() and constructs the ID class based
on that, but adding a constructor that takes a string arg didn't
change the error. i don't understand what it would want for the
"class + string" constructor, so i was not sure what to try there.
can someone help interpret this error?
thanks!
