 Prin extinderea interfeţei ''java.rmi.Remote'' se specifică faptul că metodele declarate de interfaţa ''Reservation'' vor putea fi apelate din altă maşină virtuală Java. Orice obiect care implementează interfaţa ''Reservation'' va putea fi considerat un obiect "la distanţă".

 Proprietatea ''java.rmi.server.codebase'' specifică locaţia de unde pot fi încărcate definiţii pentru clasele provenind de la server. Dacă în locul unei arhive se specifică o ierarhie de directoare, aceasta trebuie încheiată prin caracterul ''’/’''. În situația în care sunt incluse mai multe fișiere, acestea trebuie să fie delimitate prin separatorul spațiu. Pentru fiecare resursă trebuie indicat și protocoul prin care aceasta este accesată (''file:%%///%%'' sau ''http:%%//%%'').
