Connector Gateway service

Question

Hi,
I am trying to use the Connector Gateway Service in order to connect to a Sap System.
I am using this code:
int res = 1;
String str = new String("");
com.sapportals.connector.connection.IConnection connection = null;
           try {
            Object connectorservice = PortalRuntime.getRuntimeResources().getService(IConnectorService.KEY);
                 com.sapportals.portal.ivs.cg.IConnectorGatewayService cgService = (com.sapportals.portal.ivs.cg.IConnectorGatewayService) connectorservice;
                 if (cgService == null) {
                      res = 1;
                      str = str + "erro1";
                 try {
ConnectionProperties cp = new ConnectionProperties(loc, user);
connection = cgService.getConnection(pf_sap_system, cp);
IInteraction ix = connection.createInteractionEx();
IInteractionSpec ixspec = ix.getInteractionSpec();
String functionName = new String("BAPI_BANK_GETLIST");
ixspec.setPropertyValue("Name", functionName);
RecordFactory rf = ix.getRecordFactory();
MappedRecord input = rf.createMappedRecord("input");
input.put("MAX_ROWS", "20");
input.put("BANK_CTRY", "PT");
MappedRecord output = (MappedRecord) ix.execute(ixspec, input);
Object rs = null;
     try {
IRecordSet v_banc = (IRecordSet) output.get("BANK_LIST");
this.htbanco.clear();
v_banc.beforeFirst();
while (v_banc.next()) {
String key  = v_banc.getString("BAN");
Vector vDados = new Vector();
String chave = v_banc.getString("BANK_KEY");
String nome = v_banc.getString("BANK_NAME");
String cidade = v_banc.getString("CITY");
vDados.add(0, chave);
vDados.add(1, nome);
vDados.add(2, cidade);
this.htbanco.put(key,vDados);
     } catch (Exception e) {
     res = 2;
     str = str + "erro2";
            response.write((e.getLocalizedMessage()).toString());
     ix.close();
     connection.close();
          } catch (Exception e) {
     res = 3;
     str = str + "erro3";
     if (connection == null) {
     res = 4;
     str = str + "erro4";
} catch (Exception e) {
     res = 5;
     str = str + "erro5";
     return res;                           
Unfortunaly i do not get the desired results. I debug the application and between the next two lines the application leaves the method without the IInteraction.
connection = cgService.getConnection(pf_sap_system, cp);
(at this point)
IInteraction ix = connection.createInteractionEx();
Can someone tell me the issues i have to check. I am novice in this matter and i am tryng to use a tutorial of the SAP Portals.
Thank you for your time
            Best Regards
