We consider the charge and spin effects in low dimensional superconducting weak links. The first
 part of the review deals with the effects of electron—electron interaction in Superconductor/
 Luttinger liquid/Superconductor junctions. The experimental realization of this mesoscopic hybrid
 system can be the individual single wall carbon nanotube that bridges the gap between two bulk
 superconductors. The dc Josephson current through a Luttinger liquid is evaluated in the limits of perfectly
 and poorly transmitting junctions. The relationship between the Josephson effect in a long SNS
 junction and the Casimir effect is discussed. In the second part of the paper we review the recent results
 concerning the influence of the Zeeman and Rashba interactions on the thermodynamical properties
 of ballistic S–QW–S junction fabricated in two dimensional electron gas. It is shown that in magnetically
 controlled junction there are conditions for resonant Cooper pair transition which results in
 giant supercurrent through a tunnel junction and a giant magnetic response of a multichannel SNS
 junction. The supercurrent induced by the joint action of the Zeeman and Rashba interactions in 1D
 quantum wires connected to bulk superconductors is predicted.
