Integrating the CData JDBC Driver for Bullhorn CRM with Ignition SCADA

Ignition is an industrial supervisory control and data acquisition (SCADA) and industrial Internet of Things (IIoT) platform from Inductive Automation. Its central Gateway service manages device connections, tags, and database connections. Ignition doesn't ship with a connector for Bullhorn CRM, so reaching Bullhorn CRM data usually means custom middleware or manual exports.

The CData JDBC Driver for Bullhorn CRM bridges this gap by exposing Bullhorn CRM as a standard Java Database Connectivity (JDBC) data source. Ignition treats any JDBC driver as a standard database connection. Once the driver is registered in the Gateway, you can query live Bullhorn CRM data from the Script Console, SQL Bridge, tags, or a Perspective or Vision screen, without replication, custom connectors, or extract, transform, load (ETL) pipelines.

This guide outlines the steps to install and commission Ignition, register the CData JDBC Driver for Bullhorn CRM, create the connection, and verify it with a live query.

Prerequisites

• Ignition for Windows (Windows 10/11 or Windows Server), with administrator rights to install a Windows service
• CData JDBC Driver for Bullhorn CRM
• A Bullhorn CRM account with valid credentials and application programming interface (API) access enabled
• A supported desktop browser (Google Chrome, Mozilla Firefox, Microsoft Edge, or Safari) to open the Gateway web interface

Step 1: Install and set up Ignition

If Ignition is already installed and running, skip to Step 2.

Download Ignition

1. Go to the Inductive Automation downloads page and download Ignition for Windows.
2. This single download is the full Ignition Gateway installer. It includes both the Gateway service and the Designer Launcher, so you don't need a separate Designer download.

Install Ignition

1. Run the installer, accept the license agreement, and choose an install location.
2. Leave Install as a Windows Service checked so the Gateway starts with Windows.
3. Finish the installer. The Gateway service starts, and a browser window opens to http://localhost:8088 and shows the Commissioning wizard. If the page shows a Browser Not Supported notice, open the same address in Chrome, Firefox, Edge, or Safari.

Commission the Gateway

1. In the Commission Ignition Gateway wizard, set a Gateway Name and create an administrator username and password.
2. Accept the End User License Agreement, then start a trial or activate a purchased Ignition license.
3. When commissioning finishes, log in with the administrator account. You land on the Gateway Home page.

Note: A trial shows a countdown timer on every Gateway page, and the timer resets when the Gateway service restarts. This is fine for testing, but production use requires a license.

Step 2: Register the CData JDBC Driver in Ignition

Ignition lets you upload any third-party JDBC driver through the Gateway web interface, without touching the file system directly.

1. Log in to the Gateway as an administrator.
2. Go to Connections > Databases > Settings, open the Drivers tab, and click Create JDBC Driver.
3. In the dialog, enter the following:
   • Name: Bullhorn CRM
   • Classname: cdata.jdbc.bullhorncrm.BullhornCRMDriver
   • Driver Type: Generic
   • Default Validation Query: SELECT Id FROM Candidate LIMIT 1
   
4. Click Create JDBC Driver. In current Ignition 8.3 releases, the create dialog doesn't include a Java archive (JAR) file upload field, so you add the JAR file in the next step.
5. Open the menu at the right of the new driver row, choose Manage JAR files, upload cdata.jdbc.bullhorncrm.jar from the lib folder of the driver installation, and save.
6. Confirm the driver shows an INSTALLED status in the drivers list.

Step 3: Create the Bullhorn CRM connection

1. Go to Connections > Databases > Connections and click Create Database Connection.
2. On the Driver Selection step, select Bullhorn CRM and click Next.
3. On the Database Setup step, set the Name to Bullhorn CRM. Leave Username empty and select None for Password, because the credentials go in the connect URL.
4. In Connect URL, enter the connection string:

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

   
5. Click Create Database Connection and confirm the connection shows a VALID status on the Database Connections page.

Connection properties for Bullhorn CRM

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

• DataCenterCode: Set this to the data center code which responds to your data center. Refer to the list of data-center-specific Bullhorn API URLs: https://bullhorn.github.io/Data-Center-URLs/

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.

Note: If a password or token contains a semicolon, the connect URL breaks, so reset it to a value without one.

Step 4: Query live Bullhorn CRM data from Ignition

With the connection valid, you can query live Bullhorn CRM data from the Designer.

1. Open the Ignition Designer Launcher, select your Gateway (click Add Designer and enter http://localhost:8088 if it isn't listed), and click Open Designer. Log in with the Gateway administrator account.
2. Open or create a project. The Designer opens with the Project Browser, Tag Browser, and Component Palette panels.
3. In the Designer, go to Tools > Script Console. In the Multiline Buffer, enter a test query and click Execute. Replace Candidate with any table available in your Bullhorn CRM connection:

   print system.db.runQuery(
       "SELECT Id, CandidateName FROM Candidate LIMIT 10",
       "Bullhorn CRM")

   
4. A successful query prints PyDataset rows:10 cols:2 in the Interactive Interpreter panel, which confirms Ignition retrieved live data from Bullhorn CRM through the CData JDBC Driver.

Note: The connection name in the script must match the name you gave the connection in Step 3.

Step 5: Verify the results

1. Print the rows and compare the values with the same records in Bullhorn CRM:

   ds = system.db.runQuery("SELECT Id, CandidateName FROM Candidate LIMIT 10", "Bullhorn CRM")
   for row in ds:
       print row["Id"], row["CandidateName"]

2. Optionally, run a second query against another table and a filtered query to confirm schema discovery and filtering.
3. Optionally, restart the Gateway service and confirm the connection returns to VALID.

Troubleshooting

Test the driver outside Ignition

To confirm the driver works independently of the Gateway, run this standalone Java example. The cdata.jdbc.bullhorncrm.jar and cdata.jdbc.bullhorncrm.lic files must be in the same directory and on the classpath.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;

public class CDataExample {
    public static void main(String[] args) throws Exception {
        Class.forName("cdata.jdbc.bullhorncrm.BullhornCRMDriver");
        String connectionString = "jdbc:bullhorncrm:DataCenterCode=CLS33;OAuthClientId=myoauthclientid;OAuthClientSecret=myoauthclientsecret;InitiateOAuth=GETANDREFRESH;";
        try (Connection conn = DriverManager.getConnection(connectionString)) {
            Statement stmt = conn.createStatement();
            ResultSet rs = stmt.executeQuery("SELECT Id, CandidateName FROM Candidate LIMIT 10");
            while (rs.next()) {
                System.out.println(rs.getString("Id") + ", " + rs.getString("CandidateName"));
            }
        }
    }
}
