We calculate higher order corrections to the resolved component of the electroproduction cross section of large- hadrons. The parton distributions in the virtual photon are studied in detail and a NLO parametrization of the latter is proposed. The contribution of the resolved component to the forward production of large- hadrons is calculated and its connection with the BFKL cross section is discussed.
