Connect to SAP Ariba Source Data in JRuby


Create a simple JRuby app with access to live SAP Ariba Source data.

JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for SAP Ariba Source makes it easy to integrate connectivity to live SAP Ariba Source data in JRuby. This article shows how to create a simple JRuby app that connects to SAP Ariba Source data, executes a query, and displays the results.

Configure a JDBC Connection to SAP Ariba Source Data

Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CData\CData JDBC Driver for SAP Ariba Source\lib).

JRuby natively supports JDBC, so you can easily connect to SAP Ariba Source and execute SQL queries. Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.

In order to connect with SAP Ariba Source, set the following:

  • API: Specify which API you would like the provider to retrieve SAP Ariba data from. Select the Supplier, Sourcing Project Management, or Contract API based on your business role (possible values are SupplierDataAPIWithPaginationV4, SourcingProjectManagementAPIV2, or ContractAPIV1).
  • DataCenter: The data center where your account's data is hosted.
  • Realm: The name of the site you want to access.
  • Environment: Indicate whether you are connecting to a test or production environment (possible values are TEST or PRODUCTION).

If you are connecting to the Supplier Data API or the Contract API, additionally set the following:

  • User: Id of the user on whose behalf API calls are invoked.
  • PasswordAdapter: The password associated with the authenticating User.

If you're connecting to the Supplier API, set ProjectId to the Id of the sourcing project you want to retrieve data from.

Authenticating with OAuth

After setting connection properties, you need to configure OAuth connectivity to authenticate.

  • Set AuthScheme to OAuthClient.
  • Register an application with the service to obtain the APIKey, OAuthClientId and OAuthClientSecret.

    For more information on creating an OAuth application, refer to the Help documentation.

Automatic OAuth

After setting the following, you are ready to connect:

    APIKey: The Application key in your app settings. OAuthClientId: The OAuth Client Id in your app settings. OAuthClientSecret: The OAuth Secret in your app settings.

When you connect, the provider automatically completes the OAuth process:

  1. The provider obtains an access token from SAP Ariba and uses it to request data.
  2. The provider refreshes the access token automatically when it expires.
  3. The OAuth values are saved in memory relative to the location specified in OAuthSettingsLocation.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the SAP Ariba Source JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.saparibasource.jar

Fill in the connection properties and copy the connection string to the clipboard.

Below is a typical JDBC connection string for SAP Ariba Source:

jdbc:saparibasource:API=SupplierDataAPIWithPagination-V4;APIKey=wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU;Environment=SANDBOX;Realm=testRealm;AuthScheme=OAuthClient;InitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to SAP Ariba Source Data

Create a new Ruby file (for example: SAPAribaSourceSelect.rb) and open it in a text editor. Copy the following code into your file:

require 'java' require 'rubygems' require 'C:/Program Files/CData/CData JDBC Driver for SAP Ariba Source 2018/lib/cdata.jdbc.saparibasource.jar' url = "jdbc:saparibasource:API=SupplierDataAPIWithPagination-V4;APIKey=wWVLn7WTAXrIRMAzZ6VnuEj7Ekot5jnU;Environment=SANDBOX;Realm=testRealm;AuthScheme=OAuthClient;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT SMVendorID, Category FROM Vendors") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

With the file completed, you are ready to display your SAP Ariba Source data with JRuby. To do so, simply run your file from the command line:

jruby -S SAPAribaSourceSelect.rb
