[necronet]

i've been trying to get this done to get Spring to manage my transaction but i keep getting this as a stacktrace

Hibernate: select this_.id_Grupo as id1_6_1_, this_.grupo as grupo6_1_, roleses2_.id_grupo as id1_3_, roles3_.id_role as id2_3_, roles3_.id_role as id1_7_0_, roles3_.role as role7_0_ from ksique.grupos this_ left outer join ksique.role_grupos roleses2_ on this_.id_Grupo=roleses2_.id_grupo left outer join ksique.roles roles3_ on roleses2_.id_role=roles3_.id_role where this_.grupo=?
