Hibernate SessionFactory getCurrentSession is not valid without active transaction

I am facing one problem in Hibernate. Here is the code.

Configuration cfg = new Configuration().configure();
SessionFactory factory = cfg.buildSessionFactory();
Session session = factory.openSession();

Transaction trans = session.beginTransaction();
trans.begin();
Session session2 = factory.getCurrentSession();
System.out.println(session2.isConnected());

trans.commit();

And in my cfg file

<session-factory>
<property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
<property name="hibernate.connection.url">jdbc:sqlserver://localhost:1433</property>
<property name="hibernate.connection.username">username</property>
<property name="connection.password">password</property>
<property name="connection.pool_size">5</property>
<property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
<property name="hibernate.current_session_context_class">thread</property>
<property name="show_sql">true</property>
<property name="hbm2ddl.auto">false</property>
<mapping resource="Test.hbm.xml"/>
</session-factory>

when i run the application with above code it is giving me an

Exception

saying “

org.hibernate.HibernateException: isConnected is not valid without active transaction

”

I don’t know what behavior its performing internally. Any idea’s please.

if you look at the Java doc of

SessionFactory.html#getCurrentSession

Obtains the current session. The definition of what exactly “current” means controlled by the

CurrentSessionContext impl

configured for use.

So your

session

and

session2

are two different sessions. So you will have to start the transaction on

session2

to access

isConnected()

.

However if you used

getCurrentSession()

to retrieve first session then second time

getCurrentSession()

will return you the same instance.

Session session = factory.getCurrentSession();//Use getCurrentSession rather than openSession
Transaction trans = session.beginTransaction();
trans.begin();

Session session2 = factory.getCurrentSession();//Same session will be returned.

System.out.println(session2.isConnected());
trans.commit();
