Hi,
  My problem is that the EJB can't update the rows.It didn't update the fields 
title,artist,type and notes after
ejbStore() is invoked.Or in another word, The update of EJB is not successful.
  For example,after the EJB creates the the row with the PK value of '1' and updates 
the other fields with corresponding values (you can see from the log).I check the 
table with a select and find that only the PK values in the table.
  Ideally,I want to update the row with the following values:
     artist=Koopman
     notes=Incl. Toccata & Fugue in D minor
     type=classical, organ
     title=Great Organ Works/Bach JS
     id=1
  Actually,the EJB doesn't update the values of fields title,artist,type and 
notes.They are all nulls.
  This is my real problem.

[JAWS] Store command executing: UPDATE music_cd SET 
cd_artist=?,cd_notes=?,cd_type=?,cd_title=? WHERE cd_id=?
[JAWS] Set parameter: idx=1, jdbcType=VARCHAR, value=Koopman
[JAWS] Set parameter: idx=2, jdbcType=VARCHAR, value=Incl. Toccata & Fugue in Dminor
[JAWS] Set parameter: idx=3, jdbcType=VARCHAR, value=classical, organ
[JAWS] Set parameter: idx=4, jdbcType=VARCHAR, value=Great Organ Works/Bach JS
[JAWS] Set parameter: idx=5, jdbcType=CHAR, value=1
[JAWS] Rows affected = 0
[CDCollectionBean] CDBean.ejbStore()                                       Here 
ejbStore() is invoked!!
           
Thank you
