Sequence for entity's generated ID is not commited

[chalu]

Hello,

I have JBoss AS 7 + PostgreSQL 9 as storage for entity beans with ID PK generated by db sequences. Works fine until app server restart - after restart entity got already used ID.

When I look into db sequence, I see that it is not updated.

My db datasource in configuration/standalone.xml is:

<datasource jta="false" jndi-name="java:/PostgresDS" pool-name="PostgresDS" enabled="true" use-ccm="false">

                    <connection-url>jdbc:postgresql://localhost:5432/hrp</connection-url>

                    <driver-class>org.postgresql.Driver</driver-class>

                    <driver>postgresql-9.0-802.jdbc4.jar</driver>

                    <security>

                        <user-name>xxx</user-name>

                        <password>yyy</password>

                    </security>

                    <validation>

                        <validate-on-match>false</validate-on-match>

                        <background-validation>false</background-validation>

                    </validation>

                    <statement>

                        <share-prepared-statements>false</share-prepared-statements>

                    </statement>

</datasource>

I entity bean I have:

@Entity

@Table(name = "LogStep", schema = "public")

@SequenceGenerator(name = "logstep_sequence", sequenceName = "LogStep_id_seq", allocationSize = 10, initialValue = 1)

public class LogStep implements java.io.Serializable{

....

private Integer id;

....

  @Id

          @Column(name = "id", unique = true, nullable = false)

          @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "logstep_sequence")

          public Integer getId() {

                    return this.id;

          }

Could someone help me to find where is my mistake?

Thanks
