Algebraic Bethe ansatz for the supersymmetric $t-J$ model with   reflecting boundary conditions
  In the framework of the graded quantum inverse scattering method (QISM), we obtain the eigenvalues and eigenvectors of the supersymmetric $t-J$ model with reflecting boundary conditions in FFB background. The corresponding Bethe ansatz equations are obtained.
