Connect to Reckon Accounts Hosted Data in JRuby

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

Configure a JDBC Connection to Reckon Accounts Hosted 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 Reckon Accounts Hosted\lib).

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

The connector makes requests to Reckon Accounts Hosted through OAuth. Specify the following connection properties:

• SubscriptionKey: Required. You get this value when you created your developer account.
• CountryVersion: Defaults to 2021.R2.AU.
• CompanyFile: Required. The path to the company file.
• User: Required. The username of the company file.
• Password: Required. The password of the company file.
• InitiateOAuth: Set this to GETANDREFRESH to let the driver handle access tokens.
• CallbackURL: The redirectURI of your Custom OAuth App.
• OAuthClientId: The client id of your Custom OAuth App.
• OAuthClientSecret: The client secret of your Custom OAuth App.

CData provides an embedded OAuth application that simplifies OAuth desktop authentication. See the Help documentation for information on other OAuth authentication methods (web, headless, etc.), creating custom OAuth applications, and reasons for doing so.

Built-in Connection String Designer

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

java -jar cdata.jdbc.reckonaccountshosted.jar

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

Below is a typical JDBC connection string for Reckon Accounts Hosted:

jdbc:reckonaccountshosted:SubscriptionKey=my_subscription_key;CountryVersion=2021.R2.AU;CompanyFile=Q:/CompanyName.QBW;User=my_user;Password=my_password;CallbackURL=http://localhost:33333;OAuthClientId=my_oauth_client_id;OAuthClientSecret=my_oauth_client_secret;InitiateOAuth=GETANDREFRESH;

Create a JRuby App with Connectivity to Reckon Accounts Hosted Data

Create a new Ruby file (for example: ReckonAccountsHostedSelect.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 Reckon Accounts Hosted 2018/lib/cdata.jdbc.reckonaccountshosted.jar'

url = "jdbc:reckonaccountshosted:SubscriptionKey=my_subscription_key;CountryVersion=2021.R2.AU;CompanyFile=Q:/CompanyName.QBW;User=my_user;Password=my_password;CallbackURL=http://localhost:33333;OAuthClientId=my_oauth_client_id;OAuthClientSecret=my_oauth_client_secret;InitiateOAuth=GETANDREFRESH;"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Name, Balance FROM Accounts")
while (rs.next) do
 puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S ReckonAccountsHostedSelect.rb
