Connect to Microsoft Exchange Data in JRuby


Create a simple JRuby app with access to live Microsoft Exchange data.

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

Configure a JDBC Connection to Microsoft Exchange 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 Microsoft Exchange\lib).

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

Specify the User and Password to connect to Exchange. Additionally, specify the address of the Exchange server you are connecting to and the Platform associated with the server.

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Microsoft Exchange JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.exchange.jar

Fill in the connection properties and copy the connection string to the clipboard.

Below is a typical JDBC connection string for Microsoft Exchange:

jdbc:exchange:User='myUser@mydomain.onmicrosoft.com';Password='myPassword';Server='https://outlook.office365.com/EWS/Exchange.asmx';Platform='Exchange_Online';

Create a JRuby App with Connectivity to Microsoft Exchange Data

Create a new Ruby file (for example: ExchangeSelect.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 Microsoft Exchange 2018/lib/cdata.jdbc.exchange.jar' url = "jdbc:exchange:User='myUser@mydomain.onmicrosoft.com';Password='myPassword';Server='https://outlook.office365.com/EWS/Exchange.asmx';Platform='Exchange_Online';" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT GivenName, Size FROM Contacts") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S ExchangeSelect.rb

Writing SQL-92 queries to Microsoft Exchange allows you to quickly and easily incorporate Microsoft Exchange data into your own JRuby applications. Download a free trial today!
