Using CustomTypes to implement special datatypes

hi there,

I want to use a CustomType to implement the Oracle NVARCHAR/NCHAR/NCLOB datatype behaviour.
(which requires a special call before inserting/updating unicode characters - for details see http://forum.hibernate.org/viewtopic.ph ... t=nvarchar).

What class do I need to extend?
I found the description of the CustomType class in the docs, but it seems to be designed for use with polymorphistic relationships primarily.

How can I register an additional sql-type into Hibernate and use this sql-type in my hbm files?

thx alot
johannes

Note sure if it's what you need exactly, but have you looked at UserType and CompositeUserType?

thx for the hint, this is exactly what I needed.
I'll post the implementation of the UserType for the Unicode datatypes as soon as I have them.
