Transaction not active - Hibernate - JPA

Question

I have this class which is dedicated to persist data in db through persistance layer of hibernate.

public class TLinkEquipementDAOImpl implements TLinkEquipe         


        

Answer 1

I just came across this problem, and now I had solved it. But I realize that I was so stupid.

the reason I find is that the data I want to commit has a foreign key but I forget that, so the transaction will always close itself. I add the foreign key in the database, and then the test or main method run successfully.

the Key point I want to say is that please write this in your code.

} catch (Exception ex) {
ex.printStackTrace();
tx.rollback();}

and you will easily find the reason why the transaction closed or not alive. that is my experience,hope useful!
