  1. SSDG Connectors in Java

  2. SAP • Generic • Application Specific • SP • Generic • Application Specific

  3. SAP Generic Connectors

  4. Generic Synchronous API • makeSynchronousSubmitRequest() – making initial request to SSDG for availing a service in synchronous mode

  5. Asynchronous API • makeASynchronousSubmitRequest() - making initial request to SSDG for availing a service in asynchronous mode. • makeSubmitPoll() - check the status of the request which has been submitted through asynchronous mode. • makeListRequest() –get the status of all the requests submitted to SSDG during a specified time interval. • makeDeleteRequest() - delete the request and response which have already been served successfully

  6. Generic Responses • Success Status –Actual Response • Failed Status • Resubmit

  7. Elements Element Name : Classid Data Type : String Mandatory : YES (for all functions) Description :Service ID of the service provided by SP. URL of the service which is hosted on the Service Provider (SP).

  8. Elements Element Name :Transactionid Data Type : String Mandatory : NO (Depends on the SAP Application Specific Connector) Description :Used by the SAP application to club multiple Submit Request into single transaction.

  9. Elements Element Name : Body Data Type : Object Mandatory : YES (for makeSynchronousSubmitRequest() , makeASynchronousSubmitRequest() ) Description : Payload for SP from SAP in the format understood by SP.

  10. Elements Element Name : correlationid Data Type : String Mandatory : YES (for functions makeSubmitPoll(), makeListRequest() ,makeDeleteRequest() ) Description : Unique identifier of the message. Used to make Submit Poll and Delete Request. Used to correlate Submit Request & subsequent Submit Poll and Delete Request.

  11. Elements Element Name : responsemode Data Type : Enum Mandatory : YES (for all functions) Description :Type of response requested by the originator. • ResponseMode.ASYNCHRONOUS • ResponseMode.SYNCHRONOUS

  12. Elements Element Name : nsdgtest Data Type : Enum Mandatory : YES(for all functions) Description :Indicates whether a message submitted to the Gateway is a test message or a real message. NSDGTest.NO –real message NSDGTest.YES-test message

  13. Elements Element Name :starttime Data Type : Calendar Mandatory : YES (for function makeListRequest()) Description :Present for making list request calls

  14. Elements Element Name : endtime Data Type : Calendar Mandatory : YES (for function makeListRequest()) Description :Present for making list request calls

  15. Elements Element Name : targetendpointurl Data Type : String Mandatory : YES (for all functions) Description :URL of the Gateway

  16. Elements Element Name : SPauthentication Data Type : Enum Mandatory : YES (for all functions) Description : For end-to-end integrity of the message to be verified by the SP, the body part of the message will be signed and the value included in the dsig:Signature element . (for this AuthenticationType must be W3CSigned)

  17. Elements Element Name :AuthenticationType Data Type : Enum Mandatory : YES (for all functions) Description : Indicates how the SAP will be authenticated to SP. Authentication Mode are of three types • Clear - AuthenticationType.CLEAR • SHA-1- AuthenticationType. ENCRYPTED • W3C signed- AuthenticationType.DIGITAL_SIGNATURE

  19. Synchronous Submit Request

  20. Synchronous Submit Requestfrom SAP SP( Back off ) Gateway SAP (portal) makeSynchronousSubmitRequest() SubmitRequest submitRequest=new SubmitRequest(); submitRequest.setTargetEndPointURL(targetEndPoint); submitRequest.setTransactionId(transactionId); submitRequest.setClassId(classId); submitRequest.setResponseMode(ResponseMode.SYNCHRONOUS); submitRequest.setNsdgTest(NSDGTest.NO); submitRequest.setSpAuthentication(SPAuthentication.NO); submitRequest.setAuthenticationType(AuthenticationType.CLEAR); submitRequest.setMessageBody(xmlObject); SubmitResponse submitResponse=new SubmitResponse(); SAPConnector connector = new SAPConnectorImpl(); submitResponse = connector.makeSynchronousSubmitRequest(submitRequest);

  21. Synchronous Response for Synchronous submit request SP Application Specific Connector Gateway SP Generic Connector callsyncSubmitRequest() //Prepare Response XmlObject obj = XmlObject.Factory.parse(body.toString()); SPResponse response=new SPResponse(); //If no error set Response Type as RESPONSE. response.setResponseType(ResponseType.RESPONSE); response.setResponse(obj); //Else if error Prepare Error object. response.setResponseType(ResponseType.ERROR); response.setResponse(obj); return response; } public Object callSyncSubmitRequest(Object body, String classid, String transactionid, String correlationID) throws XmlException, RemoteException, IOException { System.out.println("In callSyncSubmitRequest of SP Application Specific"); System.out.println("Body ::::: "+body.toString()); //Process Request. //SP Business Logic for Processing request comes here Sending Submit Response Sending Submit Response

  22. Submit Response Gateway SAP (portal) Status =FAILED if(submitResponse.getStatus().equals(RequestStatus.FAILED)) String error=""; String [] errors=submitResponse.getErrors(); for(int i=0;i<errors.length;i++) { System.out.println(errors[i]); error=error+"\n"+errors[i]; } Status = RESUBMIT if(submitResponse.getStatus().equals(RequestStatus.RESUBMIT)) System.out.println("Please RESUBMIT the request. Reason :"+submitResponse.getReason()); Status =SUCESS if(submitResponse.getStatus().equalsRequestStatus.SUCCESS)) submitResponse.getResponse().toString()); Synchronous Response
