When I execute a session.connection.commit the next execution "java.sql.SQLException: You can't operate on a closed Connection!!!"

I use this because I need execute commit part of the process. And execute new query.

I use "hibernate-c3p0-5.2.10.Final.jar". If I remove this jar, don't have error.

Without seeing the data access logic, it's impossible to figure out the problem.

The code is the same, only change hibernate version.

I have a hibernate session create with standard options.

Execute multiple select and inserts with prepareStatement.

Next execute :
session.connection.commit();

I try exeecute a new query with prepareStatement that give the error:
java.sql.SQLException: You can't operate on a closed Connection!!!

I don't close the session after commit.

It's work equal if I user HQL.

If I use Hibernate 5.1.10 work fine, and if I use 5.2.10 and remove hibernate-c3p0-5.2.10.Final.jar work fine too.

With all far of 5.2.10 get the error.

There is no session.connection in Hibernate 5. That got removed in 4.x.

If you are talking about:

Code:
session.getTransaction().commit();


Then you need to call:

Code:
session.getTransaction().begin();


after you ended the previous transaction.

I need commit a session without close the transaction.

I use "((SessionImpl)getSession()).connection().commit()"

How I can execute the same?

Code:
((SessionImpl)getSession()).connection().commit()


I suppose you are using Hibernate 3. That API has long been removed from Hibernate, and neither 3.x or 4.x are supported anymore.

You confuse how the Session and the transaction handling are supposed to work. You should read the new User Guide to get a better understanding of how these two concepts relate.
