[deepamehta-devel] Transactions

[Robert Schuster]

Hi Joerg,
ok, I have to confess I am not allto versed with all the JAX RS
annotations. After I wrote this code I saw a JAX RS example that had
"Transactional" in it and I was thinking "Hm, I probably should use that
instead of creating that Transaction object manually". :-)

Best regards
Robert
