I have problem with locking some record from ORACLE 9i DB.
I create Entity Bean, Session Bean in JDeveloper 11g.
My Persistant_Unit is:
| <persistence-unit name="HibernatePU">
| <provider>org.hibernate.ejb.HibernatePersistence</provider>
| <properties>
| <property name="hibernate.archive.autodetection"
value="class, hbm"/>
| <property name="hibernate.connection.driver_class"
value="oracle.jdbc.driver.OracleDriver"/>
| <property name="hibernate.connection.url"
value="jdbc:oracle:thin:@localhost:1521:XE"/>
| <property name="hibernate.connection.username" value="zoran"/>
| <property name="hibernate.connection.password" value="zoran"/>
| <!-- <property name="hibernate.show_sql" value="false"/> -->
| <property name="hibernate.dialect"
value="org.hibernate.dialect.OracleDialect"/>
| <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
| </properties>
| </persistence-unit>
|
In Java class I wrote:
|
| private EntityManagerFactory EntityManagerFactoryM =
Persistence.createEntityManagerFactory("HibernatePU");
|
| private EntityManager EntityManagerMesto;
|
| EntityManagerMesto = EntityManagerFactoryM.createEntityManager();
|
|
| private void Transaction()
| {
| Mesto mestoTB = EntityManagerMesto.find(Mesto.class,1);
|
| EntityTransaction transactionM =
EntityManagerMesto.getTransaction();
|
| transactionM.begin();
|
| EntityManagerMesto.lock(mestoTB, LockModeType.WRITE);
|
| System.out.println("testEJB: " + mestoTB.getNaziv());
| }
|
|
| Private void ExitForm()
| {
| transactionM.rollback();
| }
|
|
|
I want to know if this is right code to LOCK one recored from ORACLE 9I and not
to allow to anybody to change that row until I call function
ExitForm() --- transactionM.rollback()
