Hi,
I am running into problems when persisting an Entity using hibernate in an ejb application and I would really need your help. The problem seems to relate to the @GeneratedId strategy IDENTITY.
First of all the environment:
* hibernate 3.6.10
* DB2 V 10
* Webspher 8.5
Second the test scenario:
(1) DB
I try to write to table
Code:
EXPERIMENT(ID INTEGER(10) PRIMARY KEY, NAME VARCHAR(255));
An SQL insert of the form: INSERT INTO EXPERIMENT(NAME) VALUES ("my name"); works perfectly and generates a new ID into the the row.
(2) Entity Beans and EJB
The entity bean looks like this, the id generation strategy is IDENTITY!
Code:
@Entity
public class Experiment implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
private int id;
private String name;
....
}
The Stateless ejb with persistence context and the add method:
Code:
@Stateless
public class DBConnection_Server_Admin{
@PersistenceContext(name="server_admin")
EntityManager em;
public void addExperiment() {
Experiment e = new Experiment();
e.setName("My Experiment");
em.persist(e);
}
...
}
(3) The persistence XML hopefully defines the perstence context correctly:
Code:
<persistence-unit name="server_admin" transaction-type="JTA">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>jdbc/DB2 für Linux, UNIX und Windows - Neu</jta-data-source>
<class>com.sandbox.db.Experiment</class>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<property name="hibernate.default_catalog" value="SERVER_ADMIN"/>
<property name="hibernate.show.sql" value="true"/>
<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.WebSphereExtendedJTATransactionLookup"/>
</properties>
</persistence-unit>
Third the problem and the exceptions:
On em.persist(e) hibernate generates an insert statement leading to a jdbc expcetion. The Application attempts to insert null into the id column. Here a sketch of the exceptions.
Code:
Caused by: com.ibm.db2.jcc.am.SqlIntegrityConstraintViolationException: DB2 SQL Error: SQLCODE=-407, SQLSTATE=23502, SQLERRMC=TBSPACEID=2, TABLEID=771, COLNO=0, DRIVER=3.63.123
further causing the
Code:
Caused by: org.hibernate.exception.ConstraintViolationException: could not insert: [com.sandbox.db.Experiment]
The hibernate log contains the statement sent to the database:
Code:
2012-08-24 16:13:50 DEBUG [WebContainer : 0 logExceptions 225] org.hibernate.util.JDBCExceptionReporter: could not insert: [com.sandbox.db.Experiment] [insert into SERVER_ADMIN.Experiment (id, name) values (null, ?)]
(the remainder of the log is at the end)
My current conclusion:
Hibernate resp my hibernate setup seems to somehow miss the @GeneratedId strategy and generates a preparedstatement containing the id column with a null value.
I tested additionally:
* SELECT and DELETE on the entity manager works.
* plain sql INSERT using the same jdbc driver works.
* the same code using openEJB as persistence provider works.
* using hibernate in a non EntityManager scenario works.
I am pretty stuck right now and I would really apreciate any help on this issue.
Thank you,
Dietmar
