  We present two classes of brane solutions in pp-wave spacetime. The first
class of branes with a rotation parameter are constructed in an exact string
background with NS-NS and R-R flux. The spacetime supersymmetry is analyzed by
solving the standard Killing spinor equations and is shown to preserve the same
amount of supersymmetry as the case without the rotation. This class of branes
do not admit regular horizon. The second class of brane solutions are
constructed by applying a null Melvin twist to the brane solutions of flat
spacetime supergravity. These solutions admit regular horizon. We also comment
on some thermodynamic properties of this class of solutions.
