Connect to Oracle Service Cloud Data in JRuby

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

Configure a JDBC Connection to Oracle Service Cloud 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 Service Cloud\lib).

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

Using Basic Authentication

You must set the following to authenticate to Oracle Service Cloud:

• Url: The Url of the account to connect to.
• User: The username of the authenticating account.
• Password: The password of the authenticating account.

Built-in Connection String Designer

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

java -jar cdata.jdbc.oracleservicecloud.jar

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

Below is a typical JDBC connection string for Oracle Service Cloud:

jdbc:oracleservicecloud:Url=https://abc.rightnowdemo.com;User=user;Password=password;

Create a JRuby App with Connectivity to Oracle Service Cloud Data

Create a new Ruby file (for example: OracleServiceCloudSelect.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 Service Cloud 2018/lib/cdata.jdbc.oracleservicecloud.jar'

url = "jdbc:oracleservicecloud:Url=https://abc.rightnowdemo.com;User=user;Password=password;"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Id, LookupName FROM Accounts")
while (rs.next) do
 puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S OracleServiceCloudSelect.rb
