Hello
I have some problem with my database connection.
When i want to persist my object to my database, the server don't throw an
exception but it don't insert into my table.
And when i see my debug log, it says
14:50:21,848 DEBUG [org.hibernate.engine.transaction.internal.TransactionCoordinatorImpl]

try

//$NON-NLS-1$
if (emf != null)
{
em = emf.createEntityManager();
}
if (em != null)
{
log.debug("Em Cree"); //$NON-NLS-1$
}
else
{
log.debug("Em plante"); //$NON-NLS-1$
}
}
catch (final NamingException e)
{
throw new IllegalStateException("EntityManagerFactory cannot create entity
manager"); //$NON-NLS-1$
}
return em;
}
It's an datasources error or and bad persistence.xml ?
Thanks
