Current Session method is used in along with
<property name="current_session_context_class">thread</property>

Suppose in thread t1
1)I create a session using currentsession() and add an object using that session and then close that session.
2)In the same thread if i try to create a session then will i get sessionException Session is already Closed.

I tried the following code snippet and it worked fine
public static void main(String[] a) throws Exception
{
Session session=HibernateUtil.currentSession();
session.beginTransaction();
SmHostBean bean=new SmHostBean();
bean.setId(111L);
bean.setIpaddress("1");
bean.setPort("11");
session.save(bean);
session.getTransaction().commit();
bean=new SmHostBean();
bean.setId(112L);
bean.setIpaddress("1");
bean.setPort("11");
session=HibernateUtil.currentSession();
session.beginTransaction();
session.save(bean);
session.getTransaction().commit();

}

Note:HibernateUtil is my custom class here.HibernateUtil.currentsession() in turn calls sessionFactory.getCurrentSession().


The reasion I am asking this question is because in my web application i m facing this problem of Session is Closed

what i am doing in my application is

1)From the User Interface I click on a button which starts a process in which i call three functions one after the other.
In all the three functions i am opening and closing the session.(the first two functions are called in 2 new threads i.e i spwan 2 threads after clicking on the button on the UI)
But in the third function, if i try to open a session (using currentsession()), i get an exception saying Session is already closed.

Is my code snippet above depict the same thing that i am trying to do in my web application.

Kindly help

No knows the ans to this prob?? ..Kindly help

Well the code snippet you gave is different because everything is in the same thread.

So in your post you keep mentioning that in your application you open and close the session. Actually with the currentSession() approach you wouldn't have to explicitly close the session.

I'd be curious to see the code in the three functions and how the threads are spawned.

The code i had posted was to indicate my understanding of open and current session method. In my application code i do session.getTransaction().commit(),so it closes my session.
The following code depicts what i m doing in my application

class SchedulerAction()
{

public void callSync()
{

SmDbreplication manager=new SmDbreplication ();
manager.replicate();

//spawn new thr
DialPlan d=new DialPlan();
d.start();

now open session here// this is where i get exception.In the previous threads i do not get session close exception
}

}

class SmDbreplication ()
{

// spwan n no of threads here
void replicate()
{
//in a loop
InsertionWorkThread thr=new InsertionWorkThread ();
thr.start();

//wait for all threads to return
}
}


class InsertionWorkThread ()
{

public void run()
{
//open session
//store data

//commit session
}

}

class DialPlan()
{

public void run()
{
//open session
//store data

//commit session
}

}

Hi,
I understood the difference by going through the hibernate source code and it helped me solve my problem also.

Thanks
