Hibernate transaction not successfully started

Question

Consider this simple Hibernate scenario:

session = getHibernateSession(); tx = session.beginTransaction(); SomeObject o = (SomeObject) session.get(SomeObject.class, objectId); tx.commit(); 

This code produces the following exception:

org.hibernate.TransactionException: Transaction not successfully started     at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:100)     at com.bigco.package.Clazz.getSomeData(Clazz.java:1234) 

What's going on?

Answer 1

Well, it looks like once we reach the tx.commit() line, the transaction has already been committed. My only guess is that Hibernate already commits the transaction when get()ing the object.

The fix for this is simple:

// commit only if tx still hasn't been committed yet (by hibernate) if (!tx.wasCommitted())     tx.commit();
