Connect to SAP Business One Data in JRuby

Create a simple JRuby app with access to live SAP Business One data.

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

Configure a JDBC Connection to SAP Business One 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 SAP Business One\lib).

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

To authenticate to SAP Business One you must provide the Userand Passwordproperties.

To connect to data, specify Url. This is your SAP Business One Service Layer root URL.

Built-in Connection String Designer

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

java -jar cdata.jdbc.sapbusinessone.jar

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

Below is a typical JDBC connection string for SAP Business One:

jdbc:sapbusinessone:Url=http://localhost:50000/b1s/v1;User=username;Password=password;CompanyDB=dbname;InitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to SAP Business One Data

Create a new Ruby file (for example: SAPBusinessOneSelect.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 SAP Business One 2018/lib/cdata.jdbc.sapbusinessone.jar' url = "jdbc:sapbusinessone:Url=http://localhost:50000/b1s/v1;User=username;Password=password;CompanyDB=dbname;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT DocEntry, DocType FROM Orders") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S SAPBusinessOneSelect.rb
