hi all, i hava some problems with transactions again: problem is that i want to manage them by myself not like this : Session Bean | @Remote(UserManager.class) | public @Stateless | class UserManagerBean implements UserManager { | | @PersistenceContext(unitName = "Oracle") | private EntityManager oracleManager; | | @TransactionAttribute(TransactionAttributeType.REQUIRED) | public UserRecord login(User userObject,UserContext context) throws MagtiException { | try { | oracleManager.persist(userObject); | } catch (Exception e) { | e1.printStackTrace(); | } | } | then i did some changes : I Version by some EJB3 Documentation | @Remote(UserManager.class) | public @Stateless | class UserManagerBean implements UserManager { | | @Resource public UserTransaction utx; | @Resource public EntityManagerFactory factory; | | @TransactionAttribute(TransactionAttributeType.REQUIRED) | public UserRecord login(User userObject,UserContext context) throws MagtiException { | try { | utx.begin(); | oracleManager.persist(userObject); | utx.commit(); | } catch (Exception e) { | utx.rollback(); | e1.printStackTrace(); | } | } | but i get an error like this : | java.lang.IllegalStateException: Container UserManagerBean: it is illegal to inject UserTransaction into a CMT bean | at org.jboss.ejb3.injection.UserTransactionFieldInjector.<init>(UserTransactionFieldInjector.java:46) | if i remove this : @TransactionAttribute(TransactionAttributeType.REQUIRED) the problem was not resolved. In II version program succsessfully deployed but i get an error again Session Bean | @Remote(UserManager.class) | public @Stateless | class UserManagerBean implements UserManager { | | @PersistenceContext(unitName = "Oracle") | private EntityManager oracleManager; | | @TransactionAttribute(TransactionAttributeType.REQUIRED) | public UserRecord login(User userObject,UserContext context) throws MagtiException { | try { | oracleManager.getTransaction().begin(); | oracleManager.persist(userObject); | oracleManager.getTransaction().commit(); | } catch (Exception e) { | oracleManager.getTransaction().rollback(); | e1.printStackTrace(); | } | } | in this case error was like this : | 03:42:07,015 ERROR [STDERR] java.lang.IllegalStateException: Illegal to call this method from injected, managed EntityManager | 03:42:07,015 ERROR [STDERR] at org.jboss.ejb3.entity.TransactionScopedEntityManager.getTransaction(TransactionScopedEntityManager.java:219) | ooo ya there is my persistance.xml file : | <?xml version="1.0" encoding="ISO-8859-1" ?> | | <persistence xmlns="http://java.sun.com/xml/ns/persistence" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" | version="1.0"> | <persistence-unit name="Oracle" transaction-type="JTA"> | <jta-data-source>java:/XAOracleDS</jta-data-source> | <class>com.magti.businesslayer.ejb3entity.oracle.User</class> | <properties> | <property name="hibernate.dialect" value="org.hibernate.dialect.OracleDialect"/> | <property name="hibernate.connection.driver_class" value="oracle.jdbc.OracleDriver"/> | <property name="hibernate.connection.url" value="jdbc:oracle:thin:@192.168.9.133:1521:devnbtwo"/> | <property name="hibernate.connection.username" value="USER_MANAGER"/> | <property name="hibernate.connection.password" value="USER_MANAGER"/> | <property name="hibernate.default_schema" value="USER_MANAGER"/> | </properties> | </persistence-unit> | </persistence> | COULD ANYBODY HELP ME. i don't know how i can manage transactions by myself :( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3963557#...
