i am having a problem for making my id field as oof custom type. i have been able to make my non-id fields as of custom type say a long field in DB as of Money type using UserType . is the same possible for id field as well , say i want to make my id long field to apppear as EntityId?

i tried it but it's giving problem with id-generation process, i suppose. i tried different combinations for id-generators as well? is it necessary to make the id-generator custom as well?

please explain the process of making id-generators as custom. i am interested in using id-generator as follows :

<generator class="sequence">
<param name="sequence">ID_GENERATOR_SEQ</param>
</generator>

please tell the possible options that i can have to make my id field as of custom type.
