Id var not updated after persist

[galrub]

hello all, using jboss 4.2.2 (red-hat developer studio) and mysql 5;

after doing persist the Id retrun null... here is the code:

1st, the table in DB:

create table test (
 ID int(10) NOT NULL auto_increment,
 NAME VARCHAR(15),
 PRIMARY KEY (ID)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

the -ds.xml

<datasources>
 <local-tx-datasource>
 <jndi-name>work.datasource</jndi-name>
 <connection-url>jdbc:mysql://localhost:3306/work</connection-url>
 <driver-class>com.mysql.jdbc.Driver</driver-class>
 <user-name>un</user-name>
 <password>pw</password>
 <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
 <valid-connection-checker-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLValidConnectionChecker</valid-connection-checker-class-name>
 <metadata>
 <type-mapping>mySQL</type-mapping>
 </metadata>
 </local-tx-datasource>
</datasources>

the persistence.xml

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" ...............
<persistence-unit name="tester" transaction-type="JTA">
 <jta-data-source>java:/work.datasource</jta-data-source>
 <properties>
 <property name="hibernate.dialect" value="org.hibernate.dialect.MySQL5InnoDBDialect"/>
 <property name="hibernate.show_sql" value="true"/>
 </properties>
 </persistence-unit>
</persistence>

the entity, manager, end tester EJB's:

@Entity
@Table(name = "test")
public class TestEntity implements Serializable
{
 @Id
 @Column(name = "id")
 @GeneratedValue
 private Integer someId;

 @Column(name = "name")
 private String someName;

 getters/Setters.......

 public String toString()
 {
 return "id = " + someId + ", Name = " + someName;
 }
}

public @Stateless class TestManagerBean implements TestManager
{
 private String GET_BY_ID_EJBQL = "SELECT x FROM TestEntity x WHERE x.id = ?";

 @PersistenceContext(unitName="tester")
 private EntityManager manager;

 public void create(TestEntity test)
 {
 manager.persist(test);
 }

 public TestEntity getById(Integer id)
 {
 return (TestEntity) manager.createQuery(
 GET_BY_ID_EJBQL).setParameter(1, id).getSingleResult();
 }

}

public @Stateless class RunTestBean implements RunTest
{

 @EJB private TestManager manager;

 public void test()
 {
 TestEntity testEntity = new TestEntity();
 testEntity.setSomeName("abcd");
 manager.create(testEntity);
 System.out.println("return = " + testEntity);
 }

}

there is also a standalone the looks up "RunTestBean/remote"
and execute test().

the output print out is:
15:12:00,852 INFO [STDOUT] return = id = null, Name = abcd

can anyone tell me how to "persuade" the container to kindly update the id
from the table (the persist works, got a new line in table!).

Thanks in advance
