Connect to Bullhorn CRM Data in JRuby


Create a simple JRuby app with access to live Bullhorn CRM data.

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

Configure a JDBC Connection to Bullhorn CRM 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 Bullhorn CRM\lib).

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

Begin by providing your Bullhorn CRM account credentials in the following:

If you are uncertain about your data center code, codes like CLS2, CLS21, etc. are cluster IDs that are contained in a user's browser URL (address bar) once they are logged in.

Example: https://cls21.bullhornstaffing.com/BullhornSTAFFING/MainFrame.jsp?#no-ba... indicates that the logged in user is on CLS21.

Authenticating with OAuth

Bullhorn CRM uses the OAuth 2.0 authentication standard. To authenticate using OAuth, create and configure a custom OAuth app. See the Help documentation for more information.

Built-in Connection String Designer

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

java -jar cdata.jdbc.bullhorncrm.jar

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

Below is a typical JDBC connection string for Bullhorn CRM:

jdbc:bullhorncrm:DataCenterCode=CLS33;OAuthClientId=myoauthclientid;OAuthClientSecret=myoauthclientsecret;InitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to Bullhorn CRM Data

Create a new Ruby file (for example: BullhornCRMSelect.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 Bullhorn CRM 2018/lib/cdata.jdbc.bullhorncrm.jar' url = "jdbc:bullhorncrm:DataCenterCode=CLS33;OAuthClientId=myoauthclientid;OAuthClientSecret=myoauthclientsecret;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Id, CandidateName FROM Candidate") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S BullhornCRMSelect.rb
