Integrated SOA Gateway (ISG) - Exposing Standard API as REST Web Service

 In a nutshell, we need to perform following steps to expose PL/SQL as a web service:

1. Search API in Integration Repository 

2. Deploy API as REST Service 

3. Create Grants for REST Service 

4. Invoke EBS REST Service (in JSON message format) 

5. Verify the results 

Here we will take an example of creating a user by exposing FND_USER_PKG Interface API and then invoking it to create user. 

Following steps will explain the process of exposing the standard API and then invoking it. 

Step 1: Navigate to Integration Repository Responsibility, Click on Search. 

Then on search Page enter “FND_USER_PKG” in Internal Name and click on Go 

Step 2: Click on the search result, it will display List of methods available in the Interface Package.

Click on REST Web Service Tab

This page will display List of methods that can be deployed. 

Step 3: Now select Create/Update User (we will create a user by invoking this Service once Deployed.) and enter Service Alias (This is mandatory) and then Click on Deploy button at bottom. 

You will receive message that service is successfully deployed and the status will be deployed. 

Step 4: Now you will see the link to WADL file, Click on the link. It shows the physical location of the service endpoint where the service is hosted.

<?xml version="1.0" encoding="UTF-8"?> 

<application xmlns:tns1="http://xmlns.oracle.com/apps/fnd/rest/create_user/load_row/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://wadl.dev.java.net/2009/02" xmlns:tns="http://xmlns.oracle.com/apps/fnd/soaprovider/plsql/rest/fnd_user_pkg/" targetNamespace="http://xmlns.oracle.com/apps/fnd/soaprovider/plsql/rest/fnd_user_pkg/" name="FND_USER_PKG"><grammars><include xmlns="http://www.w3.org/2001/XMLSchema" 

href="http://xxx-xxx-apdv01.cli.ad:8005/webservices/rest/Create_User/?XSD=LOAD_ROW_SYNCH_TYPEDEF.xsd"/> 

</grammars> 

<resources base="http://xxx-xxx-apdv01.cli.ad:8005/webservices/rest/Create_User/"><resource path="load_row/"> 

<method name="POST" id="LOAD_ROW"><request><representation type="tns1:InputParameters" mediaType="application/xml"/> 

<representation type="tns1:InputParameters" mediaType="application/json"/> 

</request> 

</method> 

</resource> 

</resources> 

</application> 

Now open the link highlighted in Yellow in new Browser window, it will show the XSD file with input parameters that will be used later for invoking the Web Service. 

Step 5.Now Click on the Grants Tab, select Create/Update User and then click on Create Grant button 

Step 6: Select a grantee type. 

Grantee Type can be one of the following values: 

o USER - The grantee is an individual user who was selected directly. 

o GROUP - The grantee is a group of users or a member of a group of users. 

o GLOBAL - The grant was issued to all users. 

If you selected Specific User or Group of Users, specify the user or group for which to create the grants in the Grantee Name field. 

In our case, we will enter SYSADMIN and then click on Create Grant Button. 

Now the service has been exposed as a REST interface.

We can test the REST service via POSTMAN tool. Below would be the endpoint of REST service. 

https://hostname/webservices/rest/create_user/load_row/

What is Integrated SOA Gateway (ISG) and Integration Repository Customizations

What is Integrated SOA Gateway (ISG)?

Oracle E-Business Suite Integrated SOA Gateway (ISG) is a complete set of service infrastructure to provide, consume, and administer Oracle E-Business Suite Web services. 

You can use this tool to easily discover and search on interfaces, regardless of custom or Oracle seeded ones. 

Major Features of ISG –

Oracle E-Business Suite Integrated SOA Gateway can do the following: 

• Display all Oracle E-Business Suite integration interface definitions through Oracle Integration Repository 

• Support custom integration interfaces from Oracle Integration Repository 

• Provide service enablement capability (SOAP and REST services) for seeded and custom integration interfaces within Oracle E-Business Suite 

• Use the Integration Repository user interface to perform design-time activities such as generate and deploy Oracle E-Business Suite Web services 

• Support synchronous interaction pattern for REST-based Web services 

• Support multiple authentication types for inbound service requests in securing Web service content 

• Enforce function security and role-based access control security to allow only authorized users to execute administrative functions 

• Provide centralized, user-friendly logging configuration for Web services generated through Oracle E-Business Suite Integrated SOA Gateway's service provider 

• Audit and monitor Oracle E-Business Suite inbound service operations from Service Monitor 

• Leverage Oracle Workflow Business Event System to enable Web service invocation from Oracle E-Business Suite 

Integration Repository Customizations

• Customization of Integration Repository means option to add custom interfaces into Integration Repository.

• Interfaces are programs and technologies in Integration Repository, eg. plsql, java, business events, xml gateway etc.

• Developers create and annotate custom integration interfaces based on the Integration Repository annotation standards.

• Integration administrators use a standalone design-time tool to validate these annotated source files against the annotation standards.

• After validation, a loader file is generated and then uploaded to the Integration Repository through backend processing.

• These custom interfaces are displayed based on the interface types to which they belong and displayed together with Oracle seeded ones from the Integration Repository user interface.
