Use package oracle in java

I'm running a query on my sqlDeveloper and it throws me the correct result >>24 piezas .

When I transport this query to java, it throws me a different number of pieces >>39

Here my code:

$_Query = "select sum(nvl(ln.cantidad,0)) ACUSES_ENTREGADOS "
           + " FROM    xxqp.xxqp_rec_diario_tbl    rd, "
           + " xxqp.xxqp_diario_hd_tbl     hdr, "
           + " xxqp.xxqp_diario_ln_tbl     ln "
           + " WHERE 1 = 1 "
           + " AND     rd.diario_id    =   hdr.diario_id "
           + " AND     hdr.diario_id   =   ln.diario_id "
           + " AND     ln.codigo      IS   NOT NULL "
           + " AND LN.ESTATUS=11 "
           + " AND     ln.csc_id       =   rd.csc_id "
           + " AND XXQP.XXQP_COMPROBANTE_DIARIO_PKG.XXQP_CATEGORIA_LINEA_DIARIO(Pni_diario_id => rd.diario_id "
           + " ,Pni_csc_id    => ln.csc_id "
           + " ,Pni_pieza_id  => Ln.pieza_id) = 'Acuses' "
           + " AND TO_CHAR(hdr.FECHA_CIERRE_DIARIO,'DD/MM/YYYY')='13/09/2016' "
           + " AND hdr.COLABORADOR_ID='108977'";

            clon = Gdr.getCon(2);
            st1 = clon.createStatement();
            rs1 = st1.executeQuery($_Query);
            while (rs1.next()) {
                     acusesEntregados = rs1.getInt("acuses_entregados");        
                     if (r == 0) {%>
                           <tr bgcolor='white' ALIGN='CENTER'>
                           <%
                         r = 1;
                     } else {
                        r = 0;
                        %> 
                       <tr bgcolor='#E6E6E6' ALIGN='CENTER'>
                       <%                                  
                     }%>

            <td><%=acusesEntregados%></td>

I suspect that you are not respecting this line of the query:

AND   XXQP.XXQP_COMPROBANTE_DIARIO_PKG.XXQP_CATEGORIA_LINEA_DIARIO(Pni_diario_id => rd.diario_id 
        ,Pni_csc_id    => ln.csc_id 
       ,Pni_pieza_id  => Ln.pieza_id) = 'Acuses' 

I do not know if I have to enter some configuration or have to modify the code.
