Connect to Autopilot Data in JRuby

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

Configure a JDBC Connection to Autopilot 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 Autopilot\lib).

JRuby natively supports JDBC, so you can easily connect to Autopilot 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 Autopilot Profile on disk (e.g. C:\profiles\Autopilot.apip). Next, set the ProfileSettings connection property to the connection string for Autopilot (see below).

Autopilot API Profile Settings

Locate your Autopilot API key by navigating to My Account > Autopilot API > Generate and copying the generated key.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Autopilot 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 Autopilot:

jdbc:api:Profile=C:\profiles\Autopilot.apip;ProfileSettings='APIKey=your_api_key';

Create a JRuby App with Connectivity to Autopilot 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 Autopilot 2018/lib/cdata.jdbc.api.jar'

url = "jdbc:api:Profile=C:\profiles\Autopilot.apip;ProfileSettings='APIKey=your_api_key';"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT At, BusinessName FROM Account")
while (rs.next) do
  puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S APISelect.rb
