Hello Ahmad,

You can set primary key for a entity with *prim-key *element.



For a particular *field* you can provide its *type*.



You can refer to field types from *fieldtype*.xml* files where * will be
the name of the database used. For example for Mysql there will be a file
fieldtypemysql.xml.

For *identifier* type, underlying data-structure is *String* data type for
Java and *varchar* for database (You can refer fieldtype*.xml file). So
next sequence need to be generated during create operation. When using
*entity-auto* type services it is *handled internally* but if you are
creating *custom* service for create operation you need to *generate* that.

To generate the next sequence id in create service, getNextSeqId("Entity
Name") method of GenericDelegator is used.
For example:

partyId = delegator.getNextSeqId("Party")

It will generate the next sequence for the Party entity.
