Connect to Oracle Sales Data in JRuby

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

Configure a JDBC Connection to Oracle Sales 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 Oracle Sales\lib).

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

Oracle Sales uses Basic authentication over SSL; after setting the following connection properties, you are ready to connect:

• Username: Set this to the user name that you use to log into your Oracle Cloud service.
• Password: Set this to your password.
• HostURL: Set this to the Web address (URL) of your Oracle Cloud service.

Built-in Connection String Designer

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

java -jar cdata.jdbc.oraclesalescloud.jar

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

Below is a typical JDBC connection string for Oracle Sales:

jdbc:oraclesalescloud:HostURL=https://my.host.oraclecloud.com; Username=abc123; Password=abcdef;

Create a JRuby App with Connectivity to Oracle Sales Data

Create a new Ruby file (for example: OracleSalesCloudSelect.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 Oracle Sales 2018/lib/cdata.jdbc.oraclesalescloud.jar'

url = "jdbc:oraclesalescloud:HostURL=https://my.host.oraclecloud.com; Username=abc123; Password=abcdef;"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT OptyId, Name FROM Opportunities")
while (rs.next) do
 puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S OracleSalesCloudSelect.rb
