I solves the issue, but for that I must change some configs
I used 

 <sequence-manager
className="org.apache.ojb.broker.util.sequence.SequenceManagerNativeImpl">

as sequence manager and mark the "id" field as

<field-descriptor name="id"   column="ID"   jdbc-type="INTEGER"
primarykey="true" autoincrement="true" access="readonly"/>

Then I create the table like this

CREATE TABLE EMPLOYEE(ID INTEGER NOT NULL IDENTITY PRIMARY
KEY,DEPARTMENT_ID INTEGER NOT NULL,NAME VARCHAR NOT NULL,UNIQUE(ID))

Now Im thinking about the impact to other example :-/

What do you think?
