Abstract

A relay component for a back office service creates an externally exposed REST service endpoint in front of the back office service. Instead of calling the back office service directly, REST service clients make REST service calls to the relay component using the HTTP protocol. The relay component coverts the data to XML format and sends it in a SOAP call to the back office service. The relay component receives the response from the back office service as a SOAP response that is converted to a REST message to be sent to the REST client.

Claims

1. A method for processing web service requests at a relay service, comprising:

receiving a first service call from a client, the first service call implemented using a first format;

converting the first service call to a second service call at the relay service, the second service call in a second format that is used by a back office service;

making a service call to the back office service using the second format;

receiving a first response to the second service call at the relay service, the first response in the second format;

converting the first response to a second response at the relay service, the second response in the first format; and

sending the second response to the client from the relay service.

2. The method of claim 1, further comprising:

authenticating the first service call using a security token; and

extracting user identity information from the security token to use when making the second service call to the back office service.

3. The method of claim 1, wherein the relay service and the back office service are hosted on the same device.

4. The method of claim 1, further comprising:

wherein the back office service is a group of different systems providing a single web service.

5. The method of claim 1, wherein the back office service is a group of different systems providing a plurality of different web services.

6. The method of claim 1, further comprising:

exposing a first endpoint for receiving service calls having the first format; and

exposing a second endpoint for receiving service calls having the second format.

7. The method of claim 1, wherein the first format and the second format are selected from one or more of the group consisting of:

XML-based SOAP RPCs over HTTP;

XML-based SOAP RPCs over Net.TCP;

JSON-RPC over HTTP;

JSON over HTTP;

XML-based APP over HTTP.

8. A system for providing method for processing service requests at a relay service, comprising:

a relay service application running on a relay server; and

a web service application running on an application server;

the relay service application configured to;

receive a first service call in a first format from a service client;

convert the first service call to a second service call in a second format, the second format corresponding to an interface used by the web service application; and

send the second service call to the web service application.

9. The system of claim 8, wherein the relay service application is further configured to:

receive a first response to the second service call, the first response in the second format;

convert the first response to a second response, the second response in the first format; and

send the second service response to the service client.

10. The system of claim 8, wherein the relay service application is further configured to:

receive a security token from the service client; and

authenticate the first service call using the security token.

11. The system of claim 10, wherein the relay service application is further configured to:

extract user identity information from the security token to use when making the second service call to the web service application.

12. The system of claim 8, wherein the relay server and the application server are the same device.

13. The system of claim 8, further comprising:

wherein the web service application is a group of different systems providing a single web service.

14. The system of claim 8, wherein the web service application is a group of different systems providing a plurality of different web services.

15. The system of claim 8, wherein the relay service application is further configured to:

expose a first endpoint for receiving service calls having the first format; and

exposing a second endpoint for receiving service calls having the second format.

16. A method comprising:

receiving a first service call from a client, the first service call implemented using a first format;

converting the first service call to a second service call at the relay service, the second service call in a second format that is used by a back office service;

authenticating the first service call using a security token;

extracting user identity information from the security token to use when making the second service call to the back office service; and

making a service call to the back office service using the second service call.

17. The method of claim 16, further comprising:

receiving a first response to the second service call at the relay service, the first response in the second format;

converting the first response to a second response at the relay service, the second response in the first format; and

sending the second response to the client from the relay service.

18. The method of claim 16, wherein the relay service and the back office service are hosted on the same device.

19. The method of claim 16, further comprising:

wherein the back office service is a group of different systems providing a single web service.

20. The method of claim 16, wherein the back office service is a group of different systems providing a plurality of different web services.
