    ID auto generation for MySQL on JBoss AS 7

    koshey Newbie

      Hi everyone,

      I need help to resolve such problem. Application needs to support several DB (MySQL, Oracle). After migration to JBoss 7 entity id auto generation was broken.

      Etity example:

       

       

      @Entity

      @Table(name="foo")

      public class Foo {

       

       

                private Integer id;

                private String model;

       

                @Id

                @SequenceGenerator(name="foo_seq_gen", sequenceName="foo_0", initialValue=1, allocationSize=1)

                @Column(name="id", updatable=false)

                @GeneratedValue(generator = "foo_seq_gen")

                public Integer getId() {

                          return id;

                }

                public void setId(Integer id) {

                          this.id = id;

                }

       

                @Column(name="model", length=64, updatable=false)

                public String getModel() {

                          return model;

                }

                public void setModel(String model) {

                          this.model = model;

                }

      }

       

       

      For Oracle all still works fine. But when trying to perform create operation on MySQL an error occures:

       

       

      15:34:56,290 ERROR [org.hibernate.util.JDBCExceptionReporter] (http-localhost-127.0.0.1-8080-1) Table 'scheme.foo_0' doesn't exist

       

       

      Thus MySQL tries to access unexistent table as sequence insteed use native autogeneration mechanism.

       

       

      Does anybody know the cure?

       

       

      Environment:

      MySQL 5.5.16

      JBoss AS 7.1.0.Beta1

      Hibernate 3.6.1
