Achieving interoperability between Grid infrastructures is required by all us-ers consuming computing time for projects spanning across Grid domain boundaries. Standards naturally evolve slowly and on Grid level only a few have been proposed and widely accepted so far, among them JSDL. This pa-per describes how GridSAM which supports JSDL in combination with JMEA can be used to submit jobs to a UNICORE infrastructure and hence how the number of Grid projects accessible via GridSAM can be increased right now
