Sample Script

The following is an example of a script that you add to the proxy Business Service's Service_PreInvokeMethod event handler when configuring OAuth support for Siebel REST outbound connections.

function Service_PreInvokeMethod(MethodName, Inputs, Outputs) {
//1. Get Access token from OAUTH server//
   var EAIHTTPTrasnport = TheApplication().GetService("EAI HTTP Transport");
   var Httpin = TheApplication().NewPropertySet();
   var Httpout = TheApplication().NewPropertySet();
   Httpin.SetProperty("HTTPRequestURLTemplate", "https://idcs-f03fb776674c40eb80487eb12f87a170.identity.c9dev2.
oc9qadev.com/oauth2/v1/token");
   Httpin.SetProperty("HTTPContentType", "application/x-www-form-urlencoded;charset=UTF-16");
   Httpin.SetProperty("HDR.Authorization", "Basic
YjZjYTYzNWM3YjcwNGFlYmE2NzQyNTJkYWM4YTVmYzU6YmJiOWJmZjUtYjE0NS00NTg0LTgwODItNGI4ODYwYzgwMmVk");
   Httpin.SetProperty("HTTPRequestMethod", "POST");
   Httpin.SetProperty("HTTPRequestBodyTemplate", "grant_type=client_credentials&scope=urn:opc:idm:
__myscopes__");
   Httpin.SetProperty("HTTPAccept", "*/*");
   Httpin.SetProperty("CharSetConversion", "UTF-8");
   EAIHTTPTrasnport.InvokeMethod("SendReceive", Httpin, Httpout);

// Can be removed or commented after debugging complete
   TheApplication().TraceOn("", "Allocation", "All");
   TheApplication().Trace("START - TEST v1.0");
   TheApplication().Trace(Httpout.GetValue());
   TheApplication().Trace("END - TEST");
   TheApplication().TraceOff();

//2. Extract access token from json to property set//
   var Jsoconverter = TheApplication().GetService("Siebel XSL To XML Convertor");
   var tokenPS = TheApplication().NewPropertySet();
   Jsoconverter.InvokeMethod("jsontops", Httpout, tokenPS);
   var token_type = tokenPS.GetProperty("token_type");
   var access_token = tokenPS.GetProperty("access_token");
   TheApplication().TraceOn("", "Allocation", "All");
   TheApplication().Trace("START - TEST v2.0");
   TheApplication().Trace(tokenPS.GetProperty("access_token"));
   TheApplication().Trace(tokenPS.GetProperty("token_type"));
   TheApplication().Trace(tokenPS);
   TheApplication().Trace("END - TEST");
   TheApplication().TraceOff();

//3. Add access token to proxy BS input property set//
   Inputs.SetProperty("Authorization:header", token_type + " " + access_token);
   return (ContinueOperation);
}

Modify Script (Optional)

Depending on your particular situation, you can change the previous sample script as shown in the following table.

Change	Description
HTTPRequestURL Template	In the sample script shown here, the HTTPRequestURLTemplate is set to https://idcs-f03fb776674c40eb80487eb12f87a170.identity.c9dev2.oc9qadev.com/oauth2/v1/token. You can change this URL to match the correct end point for your external service.
HDR.Authorization	"Basic <Base64 encode of client_id:client_secret>" is the Base64 Encoded value of the Client ID and Client Secret. Siebel must be registered in the Out bound server's (Resource Server) OAuth server to get the client_id & client_secret, as follows: Step 1: Register Siebel Application as a client in external applications OAuth Server. Step 2: Base64 Encode the Client ID and Client Secret obtained from Step 1. Step 3: Obtain an Access Token using Base64 Encode of the Client ID and Client Secret.

To resolve a "Cannot connect to server error"

1. Create a domain user and add it to the local Administrators group (and set the password).

2. Add the local user to the Administrator group.

3. Log in to the Siebel application with the created local user.

4. Go to the Security section of your browser and ensure that the following are set:

   • Check for the publisher's certificate revocation

   • Check for the server's certificate revocation

   • Check that TLS1.2 is set to true

5. Open Services, go to the Siebel Server Service and log in with the local user credentials.

6. Restart the Siebel Service with that user (local user).
