Connect to ZohoSubscriptions Data in JRuby

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

Configure a JDBC Connection to ZohoSubscriptions 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 ZohoSubscriptions\lib).

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

Start by setting the Profile connection property to the location of the ZohoSubscriptions Profile on disk (e.g. C:\profiles\ZohoSubscriptions.apip). Next, set the ProfileSettings connection property to the connection string for ZohoSubscriptions (see below).

ZohoSubscriptions API Profile Settings

Register an OAuth application in the Zoho Developer Console as a server-based application to obtain your Client ID and Client Secret.

Built-in Connection String Designer

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

java -jar cdata.jdbc.api.jar

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

Below is a typical JDBC connection string for ZohoSubscriptions:

jdbc:api:Profile=C:\profiles\ZohoSubscriptions.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;

Create a JRuby App with Connectivity to ZohoSubscriptions Data

Create a new Ruby file (for example: APISelect.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 ZohoSubscriptions 2018/lib/cdata.jdbc.api.jar'

url = "jdbc:api:Profile=C:\profiles\ZohoSubscriptions.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT OrganizationId, AddonCode FROM Addons")
while (rs.next) do
  puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S APISelect.rb
