JCO API which accepts system

Question

Hi all,
I want to use JCO API to connect to R/3 and call my BAPI (i.e, I am not using the JCO destination which we normally create in Web dynpro content administartor screen). This is specially for MODEL DATA (i.e., to get the application data).
I found the following API which works :-
JCO.Client C = JCO.createClient(client, userid, pwd, null, system name, system number);
C.connect();
< execute the BAPI >
C.disconnect();
Other than this, Is there any JCO API which accepts a system (which we create in the portal under system admin role) and returns a client object or gives a conneciton directly??
Any info on this would be of great help.
Regards,

Hi,
SAP had CCI with its own APIs which will solve this purpose..
Check this .This is one code i have used,, this should help..
IConnectorService service = (IConnectorService)PortalRuntime.getRuntimeResources().getService(IConnectorService.KEY);
IConnectorGatewayService cgs = (IConnectorGatewayService)service;
ConnectionProperties cp = new ConnectionProperties(request.getLocale(),request.getUser());
try {     
     IConnection conn = cgs.getConnection(system name,cp);
     Interaction ix = conn.createInteractionEx();
       IInteractionSpec ixspec = ix.getInteractionSpec();
          ixspec.setPropertyValue("Name","BAPI_SALESORDER_GETLIST");
               //---------------------------------//For scalar values
               RecordFactory rf = ix.getRecordFactory();
               MappedRecord input = rf.createMappedRecord("input");
               input.put("CUSTOMER_NUMBER","0000001000");
               input.put("SALES_ORGANIZATION","1000");
               MappedRecord output =(MappedRecord) ix.execute(ixspec,input);
               IRecordSet res =(IRecordSet)output.get("SALES_ORDERS");
