[Hibernate-commits] Using GUID as object ids.

[Alok P. <ap...@dm...>]

Hi,

We use GUID (mapped to an Oracle RAW(16)) as out object id/primary keys. The
skeletal GUID class looks like this

class GUID {

public byte[] getBytes() {...}
public void setBytes(byte[] bits) {...}

}

We would like to bind these GUIDs as byte[] (PreparedStatement.setBytes) and
I am trying to figure out what should
the class mapping look like For example I have it currently defined as :


      <class name="test.Person" table="PERSON" >
                <id name="bits" type="binary" column="GUID">
                </id>
                <property name="name" type="string"/>
        </class>

and I get the following error when I try to insert a Person object.

17-Dec-2002 11:22:48.679 [ERROR] DatastoreImpl: Could not compile the
mapping document
cirrus.hibernate.MappingException: illegal use of an array as an identifier

        at
cirrus.hibernate.impl.DatastoreImpl.storeFile(DatastoreImpl.java:68)



How do I specify the type of the GUID?


Thanks
