Connect to Salesforce Data in JRuby
Create a simple JRuby app with access to live Salesforce data.
JRuby is a high-performance, stable, fully threaded Java implementation of the Ruby programming language. The CData JDBC Driver for Salesforce makes it easy to integrate connectivity to live Salesforce data in JRuby. This article shows how to create a simple JRuby app that connects to Salesforce data, executes a query, and displays the results.
About Salesforce Data Integration
Accessing and integrating live data from Salesforce has never been easier with CData. Customers rely on CData connectivity to:
- Access to custom entities and fields means Salesforce users get access to all of Salesforce.
- Create atomic and batch update operations.
- Read, write, update, and delete their Salesforce data.
- Leverage the latest Salesforce features and functionalities with support for SOAP API versions 30.0.
- See improved performance based on SOQL support to push complex queries down to Salesforce servers.
- Use SQL stored procedures to perform actions like creating, retrieving, aborting, and deleting jobs, uploading and downloading attachments and documents, and more.
Users frequently integrate Salesforce data with:
- other ERPs, marketing automation, HCMs, and more.
- preferred data tools like Power BI, Tableau, Looker, and more.
- databases and data warehouses.

Getting Started
Configure a JDBC Connection to Salesforce 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 Salesforce\lib).
JRuby natively supports JDBC, so you can easily connect to Salesforce and execute SQL queries. Initialize the JDBC connection with the getConnection function of the java.sql.DriverManager class.
There are several authentication methods available for connecting to Salesforce: Login, OAuth, and SSO. The Login method requires you to have the username, password, and security token of the user.
If you do not have access to the username and password or do not wish to require them, you can use OAuth authentication.
SSO (single sign-on) can be used by setting the SSOProperties, SSOLoginUrl, and TokenUrl connection properties, which allow you to authenticate to an identity provider. See the "Getting Started" chapter in 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 Salesforce JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.salesforce.jar
Fill in the connection properties and copy the connection string to the clipboard.
Below is a typical JDBC connection string for Salesforce:
jdbc:salesforce:User=username;Password=password;SecurityToken=Your_Security_Token;
Create a JRuby App with Connectivity to Salesforce Data
Create a new Ruby file (for example: SalesforceSelect.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 Salesforce 2018/lib/cdata.jdbc.salesforce.jar'
url = "jdbc:salesforce:User=username;Password=password;SecurityToken=Your_Security_Token;"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Industry, AnnualRevenue FROM Account")
while (rs.next) do
puts rs.getString(1) + ' ' + rs.getString(2)
end
With the file completed, you are ready to display your Salesforce data with JRuby. To do so, simply run your file from the command line:
jruby -S SalesforceSelect.rb
