Estou tendo implementar em java a comunicação com os gateways de pagamento PagSeguro e Pagamento Digital utilizando apache commons httpclient e não está fucionando.

Segue os códigos

Pagamento Digital

package br.com.jlartes.pagamentoDigital;

import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.PostMethod;

import br.com.jlartes.util.mail.CalcuteFreight;
import br.com.jlartes.util.mail.Cep;
import br.com.jlartes.vo.DemandVO;

public class PagamentoDigital {

    public void send(DemandVO demand) {
        String url = "https://www.pagamentodigital.com.br/checkout/pay/";
        try {
            HttpClient client = new HttpClient();
            PostMethod method = new PostMethod(url);
            CalcuteFreight cf = new CalcuteFreight();
            String cepOrigem = Cep.cepHome;
            String codService = new String();
            // Configure the form parameters
            // Loja
            method.addParameter("email_loja", "joelmoraes@hotmail.com");
            method.addParameter("tipo_integracao", "PAD");
            // Produto
            for (int i = 0; i < demand.getItens().size(); i++) {
                method
                        .addParameter("produto_codigo_" + (i + 1), String
                                .valueOf(demand.getItens().get(i).getProduct()
                                        .getId()));
                method.addParameter("produto_descricao_" + (i + 1), demand
                        .getItens().get(i).getProduct().getName());
                method.addParameter("produto_qtde_" + (i + 1), String

                                .getPrice()));
            }
            if (demand.getShipping().getName().equals("PAC")) {
                codService = "41106";
                method.addParameter("tipo_frete", "encomenda");

                method.addParameter("tipo_frete", "sedex");
            }
            double frete = cf.calculaFrete(cepOrigem, demand.getAddress()
                    .getCep(), codService, demand.getTotalDemand());
            method.addParameter("frete", String.valueOf(frete));
            // Cliente
            method.addParameter("nome", demand.getUser().getName());

            method.addParameter("complemento", demand.getAddress()
                    .getComplement());
            method
                    .addParameter("bairro", demand.getAddress()
                            .getNeighborhood());
            method.addParameter("cidade", demand.getAddress().getCity());

            method.addParameter("telefone", demand.getUser().getPhone());
            method.addParameter("email", demand.getUser().getEmail());

            // Execute the POST method
            int statusCode = client.executeMethod(method);
            if (statusCode != -1) {
                String contents = method.getResponseBodyAsString();
                System.out.println(contents);
                method.releaseConnection();
            }
