JRuby からOFX Data にデータ連携

リアルタイムOFX data に連携するシンプルなJRuby アプリケーションを作成します。

JRuby はRuby プログラミング言語の高性能で安定した、完全にスレッド化されたJava 実装です。CData JDBC Driver for OFX を使用すると、JRuby からリアルタイムOFX data へのデータ連携を簡単に実装できます。ここでは、OFX data に接続し、クエリを実行して結果を表示する簡単なJRuby アプリを作成する方法を説明します。

OFX Data にJDBC で接続

Before creating the app, note the installation location for the JAR file for the JDBC Driver (typically C:\Program Files\CDatat\CData JDBC Driver for OFX\lib).

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

The OFXUser and OFXPassword properties, under the Authentication section, must be set to valid OFX user credentials. In addition to this, you will need to configure FIURL, FIOrganizationName, and FIID, which will be specific for the financial institution. You will also need to provide application-specific settings, including OFXVersion, ApplicationVersion, and ApplicationId.

To connect to some services, you will need to provide additional account information such as AccountId, AccountType, BankId, BrokerId, and CCNumber.

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

java -jar cdata.jdbc.ofx.jar

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

Below is a typical JDBC connection string for OFX:

jdbc:ofx:OFXUser=myUser;OFXPassword=myPassword;FIID=myFIID;

OFX Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: OFXSelect.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 OFX 2018/lib/cdata.jdbc.ofx.jar' url = "jdbc:ofx:OFXUser=myUser;OFXPassword=myPassword;FIID=myFIID;" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Id, Amount FROM InvBalances") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S OFXSelect.rb

Writing SQL-92 queries to OFX allows you to quickly and easily incorporate OFX data into your own JRuby applications.Download a free trial today!
