javax.persistence.SequenceGenerator mapped to "seqhilo" and not "sequence" by org.hibernate.cfg.AnnotationBinder ---------------------------------------------------------------------------------------------------------------- Key: EJBTHREE-597 URL: http://jira.jboss.com/jira/browse/EJBTHREE-597 Project: EJB 3.0 Issue Type: Bug Affects Versions: EJB 3.0 RC7 - FD Environment: JBoss 4.0.4.GA (using EJB3 packaged in that version of JBoss), Windows XP SP1, Java 1.5.04, Oracle 9 Reporter: David Richmond Assigned To: Emmanuel Bernard @javax.persistence.SequenceGenerator(name = "Question_id_sequence", sequenceName = "S_QUESTION") is mapped to a "seqhilo" generator by org.hibernate.cfg.AnnotationBinder (line 332) which causes strange ids to be generated. These ids appear to have no relation to the actual sequence state, even though "select S_QUESTION.nextVal from dual" is generated by Hibernate through JDBC. The ids start at 50 for an intial deployment, 150 after a redeployment, then 250 for the following deployment, etc, etc. If stored procedures are used which use the S_QUESTION sequence to insert rows into the same table then a conflict will happen sometime in the future, since Hibernate does not use the value from the sequence. If I replace the above @javax.persistence.SequenceGenerator definition with: @org.hibernate.annotations.GenericGenerator(name="Question_id_sequence", strategy = "sequence", parameters = { @Parameter(name="sequence", value="S_QUESTION") } ) the actual S_QUESTION.nextVal value is used correctly by Hibernate.
