Nonequilibrium steady states (NESS) of bosonic system with Bose-Einstein condensate are investigated with the aid of the C*-gebraic method. The system consists of two free bosonic reservoirs coupled with each other. Initially the reservoirs are prepared to be in equilibrium with different temperatures and local densities. NESS are constructed as the t → +∞ limits of such initial states. Josephsoncurrents are studied as well.
