Connect to CloudConvert Data in JRuby

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

Configure a JDBC Connection to CloudConvert 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 CloudConvert\lib).

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

CloudConvert uses API key authentication. Your CloudConvert API key is used to authenticate requests as a Bearer token. You can generate or view your keys at https://cloudconvert.com/dashboard/api/v2/keys.

Using API Key Authentication

After setting the following connection properties, you are ready to connect:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to your CloudConvert API key.

Example connection string:

Profile=C:\profiles\CloudConvert.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";

Built-in Connection String Designer

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

jdbc:api:Profile=C:\profiles\CloudConvert.apip;AuthScheme=APIKey;ProfileSettings="APIKey=your_api_key";

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

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

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

jruby -S APISelect.rb
