{
    IOContainer outParameters   = null;
    Process     readExcel       = new Process( processXMLFile_ );
    IOObject    inObject        = new SimpleFileObject( excelFile_ );
    IOContainer inParameters    = new IOContainer( inObject );

    outParameters   = readExcel.run( inParameters );

    SimpleExampleSet    result  = (SimpleExampleSet) outParameters.getElementAt( 0 );

    return result;
