Hi,
again, your documentation is good, and your support as well. It's
just me too dumb to read it. Sorry for bothering you, this I
could've found out myself.
But now for something completely different (hopefully not again a
not-read-documentation-issue;)
I get the stack trace below when constructing the
EntityManagerFactory in an OSGi environment.
My entities have the following inheritance hierarchy:
class Entity {
// get/set methods common to all entity-classes
// like id and version. Methods are JP-annotated,
// but not the class itself
}
// not JPA-annotated
interface IProject {
// some get/set methods
}
@Entity
class Project implements IProject extends Entity {
// implemented get/set methods of IProject
// with JPA annotations
}
The class loaders of all these classes are passed to
MultiClassLoader I regsistered in the openjpa.ClassResolver property.
It seems that the custom openjpa.ClassResolver I specified is not
asked when preparing the unenhanced classes. Could that be?
Not sure what further information to add, I could of course send the
test- and implementation plug-in-projects. They run out-of-the-box,
provided that an Eclipse >= 3.3 is installed.

Hi,
Configuring a ClassResolver[1] with MultiLoaderClassResolver[2] may be
