  We report on a study of the B --> D DsJ(2317) and B --> D DsJ(2460) decays
based on 123.7 x 10^6 BBar events collected with the Belle detector at KEKB.
The B --> D DsJ(2317) and B --> D DsJ(2460) decays have been observed for the
first time. We observe the DsJ(2317) decay to Ds pi0 and DsJ(2460) decay to the
Ds* pi0 and Ds gamma final states. We also set the 90% CL upper limits for the
decays DsJ(2317) --> Ds* gamma, DsJ(2460) --> Ds* gamma, DsJ(2460) --> Ds pi0
and DsJ(2460) --> Ds pi+ pi-.
