I'm using ojb since yestarday and I experience some problems ...
when I use ojb for one class which takes date from one table everything
is ok, the problem begins when I have object o1 of a type AddressBO
which has an object o2 of a type AddressTypeBO and I want to take o1 and
of course have o2 filled.
And of course, when I want to do this I get error.
Any help is appreciated :)
I attached :
1) errorr description
2) java classes
3) repository.xml
1) I get this type of error :
