Create entity field SEQUENCE oracle

[Marcus]

I am creating an application with ejb and I tried to use the creation of id's of the tables handled by the data base, the idea is to make a auto_incremental of type SEQUENCE.
The problem of this is I don't know how can associate this to a bean of entity, so that at the time of doing create(), this it creates a registry in the data base with new primary key. I am using CMP Entity 2,0, in the 5.1.2 WSAD and Oracle.

The sequence of the Entity you have it to give, that is to say, create the sequence in Oracle and later you put it in the description of the EJB, in where the Entity is described to which you want to make reference

Please check this example:

in description weblogic-cmp-rdbms-jar.xml you must add the code in bold

  <weblogic-rdbms-bean> 
    <ejb-name>CertificatesTariffEjb</ejb-name>

    <data-source-name>DSUPGElectronic</data-source-name> 
    <table-map> 
      <table-name>CETA</table-name> 
      <field-map> 
        <cmp-field>cetaId</cmp-field> 
        <dbms-column>CETA_ID</dbms-column> 
      </field-map> 
      <field-map> 
        <cmp-field>cetaNumerocertificados</cmp-field> 
        <dbms-column>CETA_NUMBERCERTIFICATES</dbms-column> 
      </field-map> 
      <field-map> 
        <cmp-field>cetaTarifaminima</cmp-field> 
        <dbms-column>CETA_PRICESMINIM</dbms-column> 
      </field-map> 
      <field-map> 
        <cmp-field>trmoId</cmp-field> 
        <dbms-column>SGDT_ID</dbms-column> 
      </field-map> 
    </table-map> 
       <automatic-key-generation> 
      <generator-type>Oracle</generator-type> 
      <generator-name>CETA_SEQ</generator-name> 
      <key-cache-size>1</key-cache-size> 
    </automatic-key-generation> 
  </weblogic-rdbms-bean>
