Connect to Power BI XMLA Data in JRuby


Create a simple JRuby app with access to live Power BI XMLA data.

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

Configure a JDBC Connection to Power BI XMLA 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 Power BI XMLA\lib).

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

By default, use Azure AD to connect to Microsoft Power BI XMLA. Azure AD is Microsoft’s multi-tenant, cloud-based directory and identity management service. It is user-based authentication that requires that you set AuthScheme to AzureAD.

For more information on other authentication schemes, refer to the Help documentation.

Built-in Connection String Designer

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

java -jar cdata.jdbc.powerbixmla.jar

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

Below is a typical JDBC connection string for Power BI XMLA:

jdbc:powerbixmla:AuthScheme=AzureADInitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to Power BI XMLA Data

Create a new Ruby file (for example: PowerBIXMLASelect.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 Power BI XMLA 2018/lib/cdata.jdbc.powerbixmla.jar' url = "jdbc:powerbixmla:AuthScheme=AzureADInitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Country, Education FROM Customer") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S PowerBIXMLASelect.rb
