Hi,
I am using hibernate-tools-3.1.0.alpha5 with eclipse-SDK-3.1.1-win32. When i tried to run Hibernate Artifact Generator, it reports as following:
org.hibernate.cfg.JDBCBinderException:The type java.lang.Object spans multiple columns. Only single column types allowed for single columns.

And, how can I trigger out the XML Mapping Editor?

Could someone help me with these?
Thanks.

Regards,
Yulei

Is it because the database table has not a primary key?
