Connect to Wave Financial Data in JRuby

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

Configure a JDBC Connection to Wave Financial 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 Wave Financial\lib).

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

Connect using the API Token

You can connect to Wave Financial by specifying the APIToken You can obtain an API Token using the following steps:

1. Log in to your Wave account and navigate to "Manage Applications" in the left pane.
2. Select the application that you would like to create a token for. You may need to create an application first.
3. Click the "Create token" button to generate an APIToken.

Connect using OAuth

If you wish, you can connect using the embedded OAuth credentials. 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 Wave Financial JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.wavefinancial.jar

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

Below is a typical JDBC connection string for Wave Financial:

jdbc:wavefinancial:InitiateOAuth=GETANDREFRESH;

Create a JRuby App with Connectivity to Wave Financial Data

Create a new Ruby file (for example: WaveFinancialSelect.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 Wave Financial 2018/lib/cdata.jdbc.wavefinancial.jar'

url = "jdbc:wavefinancial:InitiateOAuth=GETANDREFRESH;"
conn = java.sql.DriverManager.getConnection(url)
stmt = conn.createStatement
rs = stmt.executeQuery("SELECT Id, DueDate FROM Invoices")
while (rs.next) do
 puts rs.getString(1) + ' ' + rs.getString(2)
end

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

jruby -S WaveFinancialSelect.rb
