Re: [eclipselink-users] About Oracle User defined types

[Tom Ware <tom.ware@xxxxxxxxxx>]

Can you explain a little more about what this custom type is?  We provide a 
number of ways you can deal with special types and your choice will depend on 
how it is derived.

At the simplest level, you can specify a Converter on the object that maps to 
the special type.  That will allow you do do some operations.

http://wiki.eclipse.org/Using_EclipseLink_JPA_Extensions_%28ELUG%29#Using_EclipseLink_JPA_Converters

Alternately, we have an event mechanism that will allow you to access the data 
at various points in the query.

http://www.eclipse.org/eclipselink/api/2.3/index.html

If the data structure is, in fact, a Struct, you may be able to make use of our 
StructConverter to operate on it as it enters and leaves the database.
