JRuby からFedEx Data にデータ連携

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

FedEx 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 FedEx\lib).

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

There are five pieces of information needed in order to authenticate its actions with the FedEx service. This information is below.

  • Server: This controls the URL where the requests should be sent. Common testing options for this are: "https://gatewaybeta.fedex.com:443/xml", "https://wsbeta.fedex.com:443/xml", "https://gatewaybeta.fedex.com:443/web-service", and "https://wsbeta.fedex.com:443/web-service"
  • DeveloperKey: This is the identifier part of the authentication key for the sender's identity. This value will be provided to you by FedEx after registration.
  • Password: This is the secret part of the authentication key for the sender's identity. This value will be provided to you by FedEx after registration.
  • AccountNumber: This valid 9-digit FedEx account number is used for logging into the FedEx server.
  • MeterNumber: This value is used for submitting requests to FedEx. This value will be provided to you by FedEx after registration.
  • 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.

The Cache Database

Many of the useful tasks available from FedEx require a lot of data. To ensure this data is easy to input and recall later, utilizes a cache database to make these requests. You must set the cache connection properties:

  • CacheProvider: The specific database you are using to cache with. For example, org.sqlite.JDBC.
  • CacheConnection: The connection string to be passed to the cache provider. For example, jdbc:sqlite:C:\users\username\documents\fedexcache.db

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

java -jar cdata.jdbc.fedex.jar

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

Below is a typical JDBC connection string for FedEx:

jdbc:fedex:Server='https://gatewaybeta.fedex.com:443/xml';DeveloperKey='alsdkfjpqoewiru';Password='zxczxqqtyiuowkdlkn';AccountNumber='110371337';MeterNumber='240134349'; PrintLabelLocation='C:\users\username\documents\mylabels';CacheProvider='org.sqlite.JDBC';CacheConnection='jdbc:sqlite:C:\users\username\documents\fedexcache.db';

FedEx Data への接続性を持つJRuby アプリを作成

Create a new Ruby file (for example: FedExSelect.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 FedEx 2018/lib/cdata.jdbc.fedex.jar' url = "jdbc:fedex:Server='https://gatewaybeta.fedex.com:443/xml';DeveloperKey='alsdkfjpqoewiru';Password='zxczxqqtyiuowkdlkn';AccountNumber='110371337';MeterNumber='240134349'; PrintLabelLocation='C:\users\username\documents\mylabels';CacheProvider='org.sqlite.JDBC';CacheConnection='jdbc:sqlite:C:\users\username\documents\fedexcache.db';" 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 FedEx data with JRuby.To do so, simply run your file from the command line:

jruby -S FedExSelect.rb

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