Connect to Missive Data in JRuby

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

Configure a JDBC Connection to Missive 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 Missive\lib).

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

Missive API Profile Settings

Generate an API token in your Missive account under Settings > API Tokens.

Built-in Connection String Designer

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

jdbc:api:Profile=C:\profiles\Missive.apip;ProfileSettings='Token=your_bearer_token';

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

url = "jdbc:api:Profile=C:\profiles\Missive.apip;ProfileSettings='Token=your_bearer_token';"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Id, Subject FROM Conversations")
while (rs.next) do
  puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S APISelect.rb
