Hi Oliver,

I've watched your presentation on Devoxx this year and I want to use it.

I'm pretty new at Spring also, but I've managed to get it al working. I only have a problem for the storing of the data.
Whenever I do a flush, I've got the exception "no transaction is in progress" (see error trace below).

I've added the configuration files. For the record, it is running against a Mysql database (just downloaded from the website).

Kind regards

Jan Verstuyft
