Connect to Wrike Data in JRuby

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

Configure a JDBC Connection to Wrike 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 Wrike\lib).

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

Wrike API Profile Settings

Obtain a permanent API token from the Wrike App Console by clicking Obtain Token.

Built-in Connection String Designer

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

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

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

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

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

jruby -S APISelect.rb
