Title: JDO: Abstract class and inheritance

����������� I have a similar question then:   ����������� Is it possible to create a base class with for abstract Unmarshal and Marshal methods (castor xml) such that I wouldn't have to explicitly cast during class loading?   ����������� I would like my code to be able to accommodate unknown, future XML schemas that become Castor-ized (as opposed to Pasteruized) into Java objects like this: ����������� ����������� BaseClass bc� = (BaseClass) �Class.forName ( newCastorizedSchemaObject );   ����������� Without having to explicitly know the type name that could happen in the future, instead of   ����������� BrandNewCastorObj� co = (BrandNewCastorObj) Class.forName ( "com.enron.shred.everything.BrandNewCastorObj" )     ����������� I am new to Castor so I suppose this could be stupid question, but is it possible to create generic Unmarshal code?   -          steve     -----O riginal Message----- From: "Legido Mart�nez, Isidoro" [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 05, 2003 4:09 AM To: [EMAIL PROTECTED] Subject: [castor-dev] JDO: Abstract class and inheritance   Hi, (Sorry if this question has been posted before but I've found it in the documentation neither the mailing list). + Is it possible to define a JDO's mapping for an abstract class. + If I've two classes: ImplClass1 and ImplClass2 and both "extends" AbstractClass, Can I perform a query on AbstractClass? I would expect to get back a collection of ImplClass1 and ImplClass2 's instances together. Thanks a lot, Isi,
