Connect to UPS Data in JRuby

Create a simple JRuby app with access to live UPS data.

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

Configure a JDBC Connection to UPS 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 UPS\lib).

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

The driver uses five pieces of information in order to authenticate its actions with the UPS service.

  • Server: This controls the URL where the requests should be sent. Common testing options for this are: https://wwwcie.ups.com/ups.app/xml and https://wwwcie.ups.com/webservices
  • AccessKey: This is an identifier that is required to connect to a UPS Server. This value will be provided to you by UPS after registration.
  • UserId: This value is used for logging into UPS. This value is the one you chose to login with when registering for service with UPS.
  • Password: This value is used for logging into UPS. This value is the one you chose to login with when registering for service with UPS.
  • AccountNumber: This is a valid 6-digit or 10-digit UPS account number.
  • PrintLabelLocation: This property is required if one intends to use the GenerateLabels or GenerateReturnLabels stored procedures. This should be set to the folder location where generated labels should be stored.

Built-in Connection String Designer

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

java -jar cdata.jdbc.ups.jar

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

Below is a typical JDBC connection string for UPS:

jdbc:ups:Server=https://wwwcie.ups.com/ups.app/xml;AccessKey=myAccessKey;Password=myPassword;AccountNumber=myAccountNumber;UserId=myUserIdInitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to UPS Data

Create a new Ruby file (for example: UPSSelect.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 UPS 2018/lib/cdata.jdbc.ups.jar' url = "jdbc:ups:Server=https://wwwcie.ups.com/ups.app/xml;AccessKey=myAccessKey;Password=myPassword;AccountNumber=myAccountNumber;UserId=myUserIdInitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT FirstName, Phone FROM Senders") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S UPSSelect.rb
