  Following the general formalism reviewed in 0810.5355 [hep-th] we present
several examples of possible D3-brane configurations on four-dimensional
generalized Kaehler geometries. We will discuss T-duality transformations in N
= 2 boundary superspace and apply the duality transformations to the
constructed D3-branes. The duality transformations lead to a systematic method
to construct coisotropic branes, even on target spaces that are not
hyper-Kaehler.
