Connect to Freshservice Data in JRuby

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

Configure a JDBC Connection to Freshservice 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 Freshservice\lib).

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

Freshservice API Profile Settings

Obtain your API Key from Profile Settings in the top-right corner of Freshservice. Your Domain is the subdomain from your account URL.

Built-in Connection String Designer

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

jdbc:api:Profile=C:\profiles\Freshservice.apip;ProfileSettings='APIKey=your_api_key;Domain=your_subdomain';

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

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

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

jruby -S APISelect.rb
