i receive generic error message says there errors in getratingclient. in xml above, have used 2 different mapping, no success. doing wrong? , yeah, it's .hbm file, set embedded content. dto's classes not mapped persistent entities.

the error is: {"errors in named queries: {getratingclienti}"} , stacktrace:
