Configure NAT Mapping using vCloud SDK

Hi All,

I am trying to configure NAT Mapping in one of my routed org n/w programatically using vCloud sdk.

code below :

          client.login(userId, password);

            for (ReferenceType adminOrgRef : client.getVcloudAdmin()
                    .getAdminOrgRefs()) {

                AdminOrganization adminOrg = AdminOrganization
                        .getAdminOrgByReference(client, adminOrgRef);

                for (ReferenceType adminOrgNetworkRef : adminOrg
                        .getAdminOrgNetworkRefs()) {
                   
                    AdminOrgNetwork adminOrgNetwork = AdminOrgNetwork
                            .getOrgNetworkByReference(client,adminOrgNetworkRef);
                   
                    System.out.println("Network Type : "+adminOrgNetwork.getResource().getName());
                   
                    if (adminOrgNetwork.getResource().getConfiguration() != null) {
                        if (adminOrgNetwork.getResource().getConfiguration().getFeatures() != null) {

            for (JAXBElement<? extends NetworkServiceType> jaxbElement : adminOrgNetwork.getResource().getConfiguration()
                                    .getFeatures().getNetworkService()) {

                if (jaxbElement.getValue() instanceof NatServiceType) {
                   
                    NatServiceType natSerType = (NatServiceType)jaxbElement.getValue();
               
                    NatPortForwardingRuleType npfruleType = new NatPortForwardingRuleType();
                   
                    npfruleType.setExternalIpAddress("10.98.127.20");
                    npfruleType.setExternalPort(80);
                    npfruleType.setInternalIpAddress("192.168.0.3");
                    npfruleType.setExternalPort(80);
                    npfruleType.setProtocol("TCP");
                   
                    NatRuleType newNtype = new NatRuleType();
                    newNtype.setPortForwardingRule(npfruleType);
                   
                    natSerType.set
                   
                    System.out.println("DONE");
