Connect to PingOne Data in JRuby



Create a simple JRuby app with access to live PingOne data.

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

Configure a JDBC Connection to PingOne 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 PingOne\lib).

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

To connect to PingOne, configure these properties:

  • Region: The region where the data for your PingOne organization is being hosted.
  • AuthScheme: The type of authentication to use when connecting to PingOne.
  • Either WorkerAppEnvironmentId (required when using the default PingOne domain) or AuthorizationServerURL, configured as described below.

Configuring WorkerAppEnvironmentId

WorkerAppEnvironmentId is the ID of the PingOne environment in which your Worker application resides. This parameter is used only when the environment is using the default PingOne domain (auth.pingone). It is configured after you have created the custom OAuth application you will use to authenticate to PingOne, as described in Creating a Custom OAuth Application in the Help documentation.

First, find the value for this property:

  1. From the home page of your PingOne organization, move to the navigation sidebar and click Environments.
  2. Find the environment in which you have created your custom OAuth/Worker application (usually Administrators), and click Manage Environment. The environment's home page displays.
  3. In the environment's home page navigation sidebar, click Applications.
  4. Find your OAuth or Worker application details in the list.
  5. Copy the value in the Environment ID field. It should look similar to:
    WorkerAppEnvironmentId='11e96fc7-aa4d-4a60-8196-9acf91424eca'

Now set WorkerAppEnvironmentId to the value of the Environment ID field.

Configuring AuthorizationServerURL

AuthorizationServerURL is the base URL of the PingOne authorization server for the environment where your application is located. This property is only used when you have set up a custom domain for the environment, as described in the PingOne platform API documentation. See Custom Domains.

Authenticating to PingOne with OAuth

PingOne supports both OAuth and OAuthClient authentication. In addition to performing the configuration steps described above, there are two more steps to complete to support OAuth or OAuthCliet authentication:

  • Create and configure a custom OAuth application, as described in Creating a Custom OAuth Application in the Help documentation.
  • To ensure that the driver can access the entities in Data Model, confirm that you have configured the correct roles for the admin user/worker application you will be using, as described in Administrator Roles in the Help documentation.
  • Set the appropriate properties for the authscheme and authflow of your choice, as described in the following subsections.

OAuth (Authorization Code grant)

Set AuthScheme to OAuth.

Get and Refresh the OAuth Access Token

After setting the following, you are ready to connect:

  • InitiateOAuth: GETANDREFRESH. To avoid the need to repeat the OAuth exchange and manually setting the OAuthAccessToken each time you connect, use InitiateOAuth.
  • OAuthClientId: The Client ID you obtained when you created your custom OAuth application.
  • OAuthClientSecret: The Client Secret you obtained when you created your custom OAuth application.
  • CallbackURL: The redirect URI you defined when you registered your custom OAuth application. For example: https://localhost:3333

When you connect, the driver opens PingOne's OAuth endpoint in your default browser. Log in and grant permissions to the application. The driver then completes the OAuth process:

  1. The driver obtains an access token from PingOne and uses it to request data.
  2. The OAuth values are saved in the location specified in OAuthSettingsLocation, to be persisted across connections.

The driver refreshes the access token automatically when it expires.

For other OAuth methods, including Web Applications, Headless Machines, or Client Credentials Grant, refer to the Help documentation.

Built-in Connection String Designer

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

java -jar cdata.jdbc.pingone.jar

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

Below is a typical JDBC connection string for PingOne:

jdbc:pingone:AuthScheme=OAuth;WorkerAppEnvironmentId=eebc33a8-xxxx-4f3a-yyyy-d3e5262fd49e;Region=NA;OAuthClientId=client_id;OAuthClientSecret=client_secret;InitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to PingOne Data

Create a new Ruby file (for example: PingOneSelect.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 PingOne 2018/lib/cdata.jdbc.pingone.jar' url = "jdbc:pingone:AuthScheme=OAuth;WorkerAppEnvironmentId=eebc33a8-xxxx-4f3a-yyyy-d3e5262fd49e;Region=NA;OAuthClientId=client_id;OAuthClientSecret=client_secret;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Id, Username FROM [CData].[Administrators].Users") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S PingOneSelect.rb
