Connect to Reckon Data in JRuby

Create a simple JRuby app with access to live Reckon data.

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

Configure a JDBC Connection to Reckon 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\lib).

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

When you are connecting to a local Reckon instance, you do not need to set any connection properties.

Requests to Reckon are made through the Remote Connector. The Remote Connector runs on the same machine as Reckon and accepts connections through a lightweight, embedded Web server. The server supports SSL/TLS, enabling users to connect securely from remote machines.

The first time you connect to your company file, you will need to authorize the Remote Connector with Reckon. See the "Getting Started" chapter of the help documentation for a guide.

Built-in Connection String Designer

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

java -jar cdata.jdbc.reckon.jar

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

Below is a typical JDBC connection string for Reckon:

jdbc:reckon:User=RCUser;Password=RCUserPassword;URL=http://remotehost:8166;

Create a JRuby App with Connectivity to Reckon Data

Create a new Ruby file (for example: ReckonSelect.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 2018/lib/cdata.jdbc.reckon.jar' url = "jdbc:reckon:User=RCUser;Password=RCUserPassword;URL=http://remotehost:8166;" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Name, CustomerBalance FROM Customers") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S ReckonSelect.rb

Writing SQL-92 queries to Reckon allows you to quickly and easily incorporate Reckon data into your own JRuby applications. Download a free trial today!
