Connect to Oracle Eloqua Reporting Data in JRuby

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

Configure a JDBC Connection to Oracle Eloqua Reporting 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 Oracle Eloqua Reporting\lib).

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

Oracle Eloqua Reporting supports the following authentication methods:

• Basic authentication (User and Password)
• OAuth 2.0 code grant flow
• OAuth 2.0 password grant flow

Basic Authentication (User and Password)

To perform authentication with a user and password, specify these properties:

• AuthScheme: Basic.
• Company: The company name associated with your Oracle Eloqua Reporting account.
• User: Your login account name.
• Password: Your login password.

OAuth Authentication (Code Grant Flow)

To authenticate with the OAuth code grant flow, you must set AuthScheme to OAuth and create a custom OAuth application. For information about how to create a custom OAuth application, see the Help documentation.

Then set the following properties:

• InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
• OAuthClientId: The client Id assigned when you registered your application.
• OAuthClientSecret: The client secret that was assigned when you registered your application.
• CallbackURL: The redirect URI that was defined when you registered your application.

When you connect, the driver opens Oracle Eloqua Reporting's OAuth endpoint in your default browser. Log in and grant permissions to the application. When the access token expires, the driver refreshes it automatically.

OAuth Authentication (Password Grant Flow)

With the OAuth password grant flow, you can use your OAuth application's credentials alongside your user credentials to authenticate without the need to grant permission manually via a browser prompt. You must create an OAuth app (see the Help documentation) to use this authentication method.

Set the following properties:

• AuthScheme: OAuthPassword
• Company: The company's unique identifier.
• User: Your login account name.
• Password: Your login password.
• OAuthClientId: The client Id assigned when you registered your custom OAuth application.
• OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.

Built-in Connection String Designer

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

java -jar cdata.jdbc.oracleeloquareporting.jar

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

Below is a typical JDBC connection string for Oracle Eloqua Reporting:

jdbc:oracleeloquareporting:AuthScheme=Basic;User=user;Password=password;Company=MyCompany;

Create a JRuby App with Connectivity to Oracle Eloqua Reporting Data

Create a new Ruby file (for example: OracleEloquaReportingSelect.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 Oracle Eloqua Reporting 2018/lib/cdata.jdbc.oracleeloquareporting.jar'

url = "jdbc:oracleeloquareporting:AuthScheme=Basic;User=user;Password=password;Company=MyCompany;"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT ,  FROM ")
while (rs.next) do
  puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S OracleEloquaReportingSelect.rb
