Good to hear that, i googled a lot and since there is no real solution to this Problem, i just felt like i´m the only one who is not willing to introduce that much complexity with a whole different query Syntax like the criteria api. i still want to write plain SQL queries no hql or jpql. > > > Sure you can use model mapper / dozer to speedup the writing of conversion > code.

I do not like to tie me to session Management, as i prefer staying stateless. For the mapping itself in my Point of view, jdbctemplate and it´s rowmapping functionality should be enough for the mapping. so at the Moment it Looks like i´m about to implement this myself... > > Cheers > Daniele > > -- You received this message because you are subscribed to the Google Groups "jOOQ User Group" group.
