Re: Re: Simple Inheritance problem with multiple class to one table mapping
Hi,
Thank for your help, but I think I solved my problem.
I don't know what I was doing wrong, but simply by rewriting by hand the
Apartment Class, I solved the problem.
Now I works really great, despite sometimes Eclipse seems to go a little crazy,
so I think I also need to update it (ver 3.0.1).
Thx,
Sylvain.

I tried your classes and they worked without problems with a normal OJB
1.0.1 (I replaced the NetworkAddressVector with a List because I don't
know about this class, and I added a dummy NetworkAddress as you didn't
post it):

the XDoclet output is the following In fact now it doesn't process the Apartement.java file, and I don't know why because It used to process the file before. However, even if the file was processed by xdoclet, there was no result in the repository file, like now when it's not processed, that's why I found it weird.

Re: Simple Inheritance problem with multiple class to one table mapping
Sylvain Juge wrote: Hi, I'm quite newbie to OJB, and I really need help. I've got one base class "AbstractRoom" and two derived classes "Room" and "Apartement", and I need to store them in one table named "abstract_rooms". The problem is that when I generate repository schema for the database, it's like if the Apartement class is dropped (even if Xdoclet process the source file), because it is not present in the resulting repository file, thus absent of AbstractRoom extends. Despite abstract_rooms table contains all columns from Rooms class, there is no one from Apartement. It seems that my class "Apartement" is not seen by XDoclet as a persitence capable class, or simply "forget" my class and I wonder what Am I doing wrong. Could you post the output of the XDoclet module ? Do you get any error/warning messages ? You can also try running Ant with the -v commandline option to get some more output.
