The database returned no natively generated identity value

Database returned no natively generated classification: Hibernatehbm.xml is configured as follows:

<id name= "id" >
<generator class= "native"/>
</id>

There was a careless little problem:

The functions of native are:

A generator from Identity,sequence and Hilo is selected by the database to generate the ID.

This will require the primary key to be set to self-growing when building the table structure in the database (auto_increment)!!!!
