Hi!
I'm relative new to Hibernate but quite an experienced java developer :)-
My problem is that SchemaExport goes wrong and the error messages are not very helpful. Se stacktrace below ...
I have just two simple classes where one of them is an abstract base class that I intend to use for all my entity classes. Se code below.
Thanks in advance!
Hibernate version:
2.1.6
Name and version of the database you are using:
MySQL 4.0.20a-nt
XDoclet version:
1.2
