We report a study of DsJ*(2317)+ and DsJ(2460)+ meson production in B decays. We observe the decays B+\ensuremath→DsJ(*)+D(*)0 and B0\ensuremath→DsJ(*)+D^(*)\ensuremath- with the subsequent decays DsJ*(2317)+\ensuremath→Ds+\ensuremathπ0, DsJ(2460)+\ensuremath→Ds+\ensuremathγ, and DsJ(2460)+\ensuremath→Ds*+\ensuremathπ0. Based on a data sample of 122.1\ifmmode×\else\texttimes\fi106 BB 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\ensuremath→DsJ(*)+D*. In addition, we perform an angular analysis of DsJ(2460)+\ensuremath→Ds+\ensuremathγ decays to test the different DsJ(2460)+ spin hypotheses.
