    jboss/oracle/xdoclet auto-increment

    Sunil Newbie

      Hi,

      I have an oracle 9i table set up with a sequence and trigger to support auto-increment. I've tried to enable this functionality on the entity bean in jboss using xdoclet tags but can't seem to get it right.


      Bean level tags:

      * @jboss.unknown-pk
       * class="java.lang.Object"
       * column-name="news_id"
       * auto-increment="true"
       *
      * @jboss.entity-command name="oracle-sequence"
      * jboss.entity-command-attribute name="sequence" value="news_increment"
      


      Method level:
      removed the primary key cmp fields from the bean class.

      I get the following error message:

      I've also tried to get the "TEST_SEQUENCE" defined in standardjbosscmp-jdbc.xml defined in oracle and use it, though getting the same results.
      Thanks again for taking the time.

      Regards,
      Sunil.

      P.S. Is there a simple example/tutorial on how to get the auto-increment feature of oracle to work with jboss entity beans (using xdoclet tags) available online?

        • 2. Re: jboss/oracle/xdoclet auto-increment
          Frank Langelage Master

          I have it working with this tags:
          at bean level I have e.g.:
          * @jboss.entity-command name="oracle-sequence"
          * @jboss.entity-command-attribute name="sequence" value="mbi_afsta_seq"

          for the primary key field then I have:
          * @jboss.auto-increment

          The PK-field is defined as usual in the bean.

          The insert-command generated by jboss looks like this then:
          [org.jboss.ejb.plugins.cmp.jdbc.keygen.JDBCOracleCreateCommand.MbiAfsta.initInsertSQL] Insert Entity SQL: {call INSERT INTO AFSTA (afsta_serial, vg_comp_nr, vg_lfd_nr, vg_tf1_nr, vg_tf2_nr, auf_art_nr, aus_art_nr, v_aus_art_nr, tf1_max, tf2_max, debitor_nr, d_adress_nr, objekt_no, avis_nr, verband_nr, v_adress_nr, r_adress_nr, regulierer, a_adress_nr, kdsbe_adress_nr, dvksb_adress_nr, erf_dat, best_dat, eing_dat, prs_bez_dat, txt_bez_dat, stat_knz, aend_nr, sperr_knz_nr, sperr_knz_sb, sprach_nr, land_nr, fw_nr, fw_rech_knz, waehr_p, kurs, forder_code, versart_nr, prl_nr, liefbed_nr, sped_nr, kfz_knz, tour_nr, tour_rang_nr, wunsch_term1, wunsch_term2, lieft_norm, lieft_kurz, lief_term1, lief_term2, termfind_dat, lief_termbmk, fert_term1, fert_term2, ltz_aenddat, ltz_aendbmk, zahlbed_knz, zahlbed_nr, skonto_nr, skonto_tage1, skonto_proz1, skonto_tage2, skonto_proz2, tage_netto, valuta_tage, valuta_dat, faellig_dat, vk_abt_nr, vk_sa_bear_1, vk_sa_bear_2, beleg_nr, beleg_dat, buch_dat, knz_verarb, knz_teillief, ltg_teillief, gewicht_netto, gewicht_brutto, volumen_cbm, prod_st, skontofaeh_lw, auft_netto_lw, auft_brutto_lw, festpr_ne_lw, preise_inc, skontofaeh_lw_inc, auft_netto_lw_inc, auft_brutto_lw_inc, festpr_ne_lw_inc, montage_knz, deb_erl_grp_nr, lager_nr_zug, lager_nr_abg, deb_best_nr, aend_dr_nr, musterk_knz, sammrech_kunde, rech_stellung, sort_nr, knz, x_kdsbe_mail, x_anz_verladepos) VALUES (mbi_afsta_seq.NEXTVAL, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) RETURNING afsta_serial INTO ? }

          You'll have to call ejbCreate with PK-Value 0.
          After EjbCreate the PK-field is filled with the value from the sequence.

          What did you mean with "trigger" ? A DB-Trigger on insert ?
          This would probably disturb the above action. Drop it.
          Or at least, make sure the trigger fills the PK-field only if value is 0.

            Sunil Newbie

            Thanks, that helped a lot. The sequence is being used now to auto-increment. and yes, the trigger isn't needed. Thanks again for the precise help!

            Regards,
            Sunil.
