16. ©Centre for Development of Advanced Computing http://ssdg.cdacmumbai.in Working with Connectors

17. ©Centre for Development of Advanced Computing http://ssdg.cdacmumbai.in Application Specific -SAP Request from SAP to avail SP service will be sent through SSDG. Application Specific Connector will take the data from SAP and will convert the request as per the format understood by SP. Application specific Connector will use the API’s of Generic Connector to send the payload as per the IIP/IIS standards to the SSDG. Application Specific Connector will be developed by IAs.

18. ©Centre for Development of Advanced Computing http://ssdg.cdacmumbai.in Generic -SAP Purpose of generic connector is to interface with gateway for standards based messaging communication. C-DAC will be providing Generic Connectors. Generic connectors are available in Java,. NET and php.

19. ©Centre for Development of Advanced Computing http://ssdg.cdacmumbai.in Generic -SP Purpose of generic connector is to check whether the message sent by SSDG is valid or not. If the message sent is valid,it passes the message to Application Specific Connector by extracting the payload and other necessary details. If the message is invalid then it sends back the message to SSDG by populating necessary error codes. C-DAC will be providing Generic Connectors. Generic connectors are available in Java,. NET.

20. ©Centre for Development of Advanced Computing http://ssdg.cdacmumbai.in Application Specific -SP Based on the payload and details provide by generic connector, application specific connectors will send the request to SPs whose services are requested. Application specific connector will send back the necessary response to SAP through SSDG. Application Specific Connector will be developed by IAs.
