[jboss-user] [EJB 3.0] - Re: help composite keys

[sashaxiv]

well, at first thank you for your time

a Ruta can have 0,n Puertos
a Puerto can be part of 0,n Rutas

the distance(which is also a attribute in Puerto and Ruta with other significant) indicates the distance beetwen the start of the Ruta and start of the Puerto. I need it to calculate a coeficient of the difficult of a Ruta.

Thanks felix!!
