JRuby からEpicor ERP Data にデータ連携

リアルタイムEpicor ERP 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 Epicor ERP を使用すると、JRuby からリアルタイムEpicor ERP data へのデータ連携を簡単に実装できます。ここでは、Epicor ERP 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。

Epicor ERP 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 Epicor ERP\lib).

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

To successfully connect to your ERP instance, you must specify the following connection properties:

  • Url:the URL of the server hosting your ERP instance. For example, https://myserver.EpicorSaaS.com
  • ERPInstance: the name of your ERP instance.
  • User: the username of your account.
  • Password: the password of your account.
  • Service: the service you want to retrieve data from. For example, BaqSvc.

In addition, you may also set the optional connection properties:

  • ApiKey: An optional key that may be required for connection to some services depending on your account configuration.
  • ApiVersion: Defaults to v1. May be set to v2 to use the newer Epicor API.
  • Company: Required if you set the ApiVersion to v2.

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

java -jar cdata.jdbc.epicorerp.jar

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

Below is a typical JDBC connection string for Epicor ERP:

jdbc:epicorerp:Service=Erp.BO.CustomerSvc;ERPInstance=MyInstance;URL=https://myaccount.epicorsaas.com;User=username;Password=password;InitiateOAuth=GETANDREFRESH

Epicor ERP Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: EpicorERPSelect.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 Epicor ERP 2018/lib/cdata.jdbc.epicorerp.jar' url = "jdbc:epicorerp:Service=Erp.BO.CustomerSvc;ERPInstance=MyInstance;URL=https://myaccount.epicorsaas.com;User=username;Password=password;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT CustNum, Company FROM Customers") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S EpicorERPSelect.rb
