Olding, who touched down against both Glasgow Warriors and Benetton Treviso, starts at full-back in a back-three combination that is completed by winger David Panter and Rory Scholes.
Joyce, a starter for the province against Glasgow, has been named at blindside flanker. Darragh Leader and Peadar Timmins will resume on the replacements bench.
Speaking ahead of the clash with France, Ruddock said: "We have a tough battle on our hands against a strong French team.
"They have recalled to their squad a number of players with Heineken Cup experience. We need to reproduce our valiant effort we showed against England."
