Connect to Zoho Books Data in JRuby

Create a simple JRuby app with access to live Zoho Books data.

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

Configure a JDBC Connection to Zoho Books 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 Zoho Books\lib).

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

Zoho Books uses the OAuth authentication standard. To authenticate using OAuth, create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the OAuth section of the Getting Started guide in the Help documentation for an authentication guide.

Built-in Connection String Designer

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

java -jar cdata.jdbc.zohobooks.jar

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

Below is a typical JDBC connection string for Zoho Books:

jdbc:zohobooks:OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;CallbackURL=https://localhost:33333;OrganizationId=MyOrganizationId;InitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to Zoho Books Data

Create a new Ruby file (for example: ZohoBooksSelect.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 Zoho Books 2018/lib/cdata.jdbc.zohobooks.jar' url = "jdbc:zohobooks:OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;CallbackURL=https://localhost:33333;OrganizationId=MyOrganizationId;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT InvoiceId, InvoiceNumber FROM INVOICES") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S ZohoBooksSelect.rb
