  We report a study of DsJ*(2317)+ and DsJ(2460)+ meson production in B decays.
We observe the decays B+ -> DsJ(*)+ Dbar(*)0 and B0 -> DsJ(*)+ D(*)- with the
subsequent decays DsJ*(2317)+ -> Ds+ pi0, DsJ(2460)+ -> Ds+ gamma, and
DsJ(2460)+ -> Ds*+ pi0. Based on a data sample of 122.1 million BBbar pairs
collected with the BaBar detector at the PEP-II B factory, we obtain branching
fractions for these modes, including the previously unseen decays B -> DsJ(*)+
D*. In addition, we perform an angular analysis of DsJ(2460)+ -> Ds+ gamma
decays to test the different DsJ(2460)+ spin hypotheses.
