Connect to SAP Fieldglass Data in JRuby


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

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

Configure a JDBC Connection to SAP Fieldglass 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 Fieldglass\lib).

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

To authenticate, you will need to specify the Username, Password, APIKey, and EnvironmentURL connection properties.

To obtain an APIKey, log in to the SAP API Business Hub and click on Get API Key.

Built-in Connection String Designer

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

java -jar cdata.jdbc.sapfieldglass.jar

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

Below is a typical JDBC connection string for SAP Fieldglass:

jdbc:sapfieldglass:EnvironmentURL='https://myinstance.com';Username=myuser;Password=mypassword;APIKey=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx;InitiateOAuth=GETANDREFRESH

Create a JRuby App with Connectivity to SAP Fieldglass Data

Create a new Ruby file (for example: SAPFieldglassSelect.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 Fieldglass 2018/lib/cdata.jdbc.sapfieldglass.jar' url = "jdbc:sapfieldglass:EnvironmentURL='https://myinstance.com';Username=myuser;Password=mypassword;APIKey=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx;InitiateOAuth=GETANDREFRESH" conn = java.sql.DriverManager.getConnection(url) stmt = conn.createStatement rs = stmt.executeQuery("SELECT Id, Category FROM AuditTrails") while (rs.next) do puts rs.getString(1) + ' ' + rs.getString(2) end

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

jruby -S SAPFieldglassSelect.rb
