Is the James Webb Telescope really a one-shot deal?

Since it will reside in the Earth-Sun L2 Lagrange point, we won't have a transport vehicle to reach it (and it would be vastly deeper into space than any human has ever gone)...so is NASA really that confident that the JWSP won't have a Hubble-esque start?

Yes, the Webb telescope will be physically un-repairable for the reasons you mentioned. But keep in mind that the Hubble was one of the only space missions ever to be designed for repairability. So the Wedd telescope will be just like all other space missions. Launch it and wish it luck. Plus build in as much redundancy as possible so problems can be fixed from the ground. But if there is Hubble like problem to start, it will be a tragedy!
Edit: Webb!
