Hi, I try to use the new tool hibernate-tools-3.0alpha1 to reverse engineering and generate the mapping and pojos. I want to map a smallInt db column to boolean in stead of short. Anyone knows how can I achieve that? Thanks.

not in the latest release - it will arrive in the cvs version soon.

Thanks for the quick response. When or how can I reverse engineering selected tables or schema?

When I try to reverse engineering derby db, it seems ok. However, when I try to reverse engineering oracle db, I got the exception of:

"Error under artifact generation

Reason:

org.hibernate.cfg.JDBCBinderException: org.hibernate.mapping.Column(OBJ_ID) already exist in org.hibernate.mapping.Table(null.DMSYS.DM_PHYSICAL_DATA)"

I think it try to reverse engineering all the system tables of oracle. What is the way I can tell the tool that I am only interested in my schema? Thanks

set default schema/catalong in your hibernate.cfg.xml

I have tried adding the following into hibernate.cfg.xml under session-factory:

<property name="hibernate.defaultSchemaName">UDC</property>
with or w/o catalog declaration:
<property name="hibernate.defaultCatalogName"></property>


But I still get the same error. Any clue? Thanks.

read the docs to get the exact names:
