i just tryed to increase the timeout size in the file transaction-service.xml but it doesn't work.
The original value was 300 and i put 20000.
Still, i got no errors ( it seems that everything is fine) but i don't find any data saved in my database.
I hope someone will help me.
Everything works fine setting a transaction timeout bigger than default one.
I set the transaction timeout to 3600 seconds.
