Setup for Desktop Red App Development

The Red App development environment consists of the Eclipse IDE, required JDKs, Red App target platform, Red App run configuration and Red App development tools software.

The procedures in this chapter help you with the first-time installation of the Sabre Red 360 Developer Toolkit.

It is required to complete all steps in each part in their order of presentation.

This chapter is organized into the following parts:

Prerequisite Software. This part will guide you step by step through the process of installing required tools.
Adding Your Red App Target Platform. These steps let you use the functionality in the Sabre Red 360 Developer Toolkit and import the Red App sample plug-ins.
Configuring and Testing Your Red App Run Configuration. This part lets you launch Sabre Red 360 in development mode from Eclipse IDE. Run the Red App sample plug-ins and do local testing of your Red App.
Installing the Red App Development Tools Software. You have to install this to access the Sabre Red 360 Developer Toolkit help. Run Red App wizards and access to the Sabre Scribe Compiler!

Note	Set up tutorials can be also found in video format on Sabre Dev Studio Youtube channel.

Prerequisite Software

Required Developer Software, Tools, and IDs

Sabre Red App Certified Developers need the following software, tools, and login credentials for Red App development:

Installation of the AdoptOpenJDK 8u282 which is obligatory in the runtime for Red App Development.

You can download the AdoptOpenJDK 8u282 from official page or from the Sabre Dev Studio Red App Developer Resources.

Installation of any distribution of JDK 11 or greater which is required by Eclipse IDE for RCP and RAP Developers 2021-12 to be set as the JAVA_HOME variable in the environment settings or set as the -vm argument in ini file.

Attempting to run eclipse with earlier versions of the JDK will fail and the error similar to the below will be shown.

Installation of Eclipse IDE for RCP and RAP Developers 2021-12 for the 64-bit Windows or macOS. Older versions of Eclipse are not compatible.

You can download this from https://www.eclipse.org/downloads/packages/ or from the Sabre Dev Studio Red App Developer Resources.

The latest version of the Sabre Red 360 Developer Toolkit. This Toolkit includes components for the Red App target platform, which is essential for Red App development. The Toolkit also has sample plug-ins, the Red App Development Tools (for using the wizards), and the Red App developer documentation. After you set up your development environment, you launch Sabre Red 360 in development mode from Eclipse IDE.

Complete installation instruction can be found in the next step Extracting the Sabre Red 360 Developer Toolkit

Login credentials with authentication to both the Certification and the Production environments of Sabre Red 360, the Sabre GDS, and the Sabre PCC.

A Pseudo City Code, or PCC, is Sabre’s 4-character alphanumeric identifier. All Red App developers receive a PCC as a part of the existing Sabre Authorized Developer on-boarding process.

These login credentials include a Sabre ID, password, and PCC. Production login credentials are used to log in to eservices.sabre.com and the Sabre Red App Centre .

More information about using your Sabre ID is included in Using Your Sabre ID and Other IDs.

Note

With the Sabre Red 360 Developer Toolkit version 2.10 or higher installed, you can start Red App development without having Certification and Production credentials set up using Sabre Red 360 Developer Toolkit Sandbox Mode, which does not require any connectivity to Sabre infrastructure and allows you to run and test your Red App against mocked Sabre Host and Sabre Web Services. When running Sabre Red 360 Developer Toolkit in Sandbox Mode you use fake credentials and do not need a Terminal Address (use pooled TA connection mode with empty pool name). However, final tests and certification of a Red App are always performed on Certification environment and do require valid credentials as well as network connectivity.

A Terminal Address (TA) with access to the Certification (CERT) environment.
Installation of the CERT and Production (PROD) environments of Sabre Red 360 for development.

After Sabre validates and certifies a Red App, developers are required to test their app in CERT, and to test their app later, in PROD Sabre Red 360. More information about environments is included in Sabre Red 360 and GDS Environments.

Compliance with the minimum network requirements to connect to the Sabre GDS:
- Sabre Customer Virtual Private Network Client (SCVPN). This is a customer-supplied Internet connection.
  
  56 Kbps or faster (56 Kbps for a single workstation only)
  
  Note
  Ports 443 & 80 are required for Sabre Red 360. Write permission is required to the etc directory (host and lmhost files) for the Sabre VPN.
- Private Connection. This is a dedicated connection to Sabre.
  - Business to Business VPN (B2BVPN)
  - Legacy Frame Relay
  - Managed Network Services (Frame or DSL)
  - Vendor Access Room connections
    
    Note
    Ports 443, 80, 389, 30030, 30031, 30032, and 30051 must be open for the Workspace communication processes to work properly.
Sabre Red App Certified Developers who want to develop applications that consume Sabre Web Services must have previously acquired credentials and a Sabre Web Services developer license agreement. Additionally, downline agreements may be required to allow agencies to run the apps that are built to consume Sabre Web Services.
Access to eservices.sabre.com. Your PRODUCTION Sabre GDS login credentials grant you access to eServices.
A digitally signed certificate to submit a Red App bundle. The company name field in certificate must be the same as the redapp bundle vendor and the certificate must be valid for a minimum of 30 days, starting from the date that Sabre validates your submitted Red App. Obtain a digital certificate from a certificate authority that Sabre supports.

Extracting the Sabre Red 360 Developer Toolkit

Create a parent folder on your local drive for Sabre Red 360 Developer Toolkit.

Note
You will also use this parent folder to upgrade to the new versions of the Toolkit.
Download Sabre Red 360 Developer Toolkit archive file (zip on Windows, tgz on macOS) to the parent folder. In Figure 1, the parent folder is sdk (in our example it is located in C:\sdk).
Extract the contents of Sabre Red 360 Developer Toolkit archive file. Make sure to retain the folder names.

Figure 1. Folder Structure of the Extracted Sabre Red 360 Developer Toolkit

When you extract the zip (on Windows) or tgz (on macOS) file into the parent folder, the archive program will automatically create a new sub-folder which have the following naming convention: red-app-sdk-*. The archive program will also create another set of sub-folders for the files. (See Figure 2.)

Figure 2. Expanded Folder Structure After Installation of Sabre Red 360 Developer Toolkit

If you finish these procedures, please go to the next step which is Adding your Red App Target Platform.

Adding a Red App Target Platform

Setup differences

Using the Java Distribution from Sabre Red 360 installation
Setting VM arguments

Using Sabre Red 360 Developer Toolkit Sandbox Mode

Sabre Red 360 Developer Toolkit Sandbox Mode is a feature that allows running and testing a Red App in isolated environment – without connectivity to Sabre infrastructure or real Sabre credentials. It may be useful as a temporary approach when your Sabre credentials are not set up yet and wanting to test the Sabre Red 360 Developer Toolkit prior to develop a real Red App, or when you need to test your Red App in specifically hard to reproduce on real environment scenarios. Sandbox Mode allows you to emulate any Host response as well as any Sabre Web Service response. In Sandbox Mode you configure Agent Profile information (like ID, language, email address).

Sabre Red 360 Developer Toolkit Sandbox Mode setup

Prerequisites

com.sabre.edge.platform.optional.sandbox plugin needs to be added to your Target Platform and Run Configuration.

Run Configuration

Follow all steps for regular configuration and add the following:

-Dredapp.fake.session=true

to VM arguments section on Arguments tab.

Credentials

As there is no connection to Sabre infrastructure, no credentials are needed. However, you still will see login screen when running Platform in Sandbox Mode. To get pass it simply, enter any 6-digit Agent ID, non-empty password and any 4-character PCC.

First run

First run is required to extract sample XML file with sets of commands and responses. It will be located in your run configuration workspace in:

.metadata\.plugins\com.sabre.edge.platform.optional.sandbox\resources\default_emulator.xml.

Your run configuration workspace is by default in the same folder as your eclipse workspace.

Sample command set file

Sabre Red 360 Developer Toolkit comes with a set of sample command/response test cases that you can change and extend providing responses that you expect for certain command. Command sets file contains 3 sections: one for host communication (both emulator and direct), one for SWS and one for agent profile data.

Host communication

<host-configuration>
	<commandset id="001">
		<command content="1KRKDFW">
			<response>
				<content>SIGN IN A</content>
			</response>
			<response delay="5000">
				<content>SECOND RESPONSE</content>
			</response>
		</command>
	</commandset>
</host-configuration>

Communication with Host is defined in this section. All commands should be defined in the same <commandset> tag. Currently, only one commandset tag is supported. Responses are defined within <content> tag. You can define one or many responses for a command. If delay attribute is defined for response it will be delivered after provided number of milliseconds. Multiple responses will be delivered in order they appear in the file.

SWS communication

<sws-configuration>
	<actionset id="001">
		<action content="OTA_AirAvailLLSRQ">
			<response>
				<content>
				<![CDATA[
					<test>TEST SWS RESPONSE</test>
				]]>
				</content>
			</response>
		</action>
	</actionset>
</sws-configuration>

SWS communication is based on actions. You can define one XML answer for each action. Response is defined in <content> tag. Remember to put your xml content in <![CDATA[ ]]> tag.

Agent profile information

<profile-configuration>
	<agent-id>AGENT_ID</agent-id>
	<agency-name>AGENCY NAME</agency-name>
	<pcc>PCC</pcc>
	<language>LANGUAGE</language>
	<country>COUNTRY</country>
	<region>REGION</region>
	<username>USERNAME</username>
	<email>fake@email.com</email>
</profile-configuration>

In this section you can provide agent information that would be available with IAgentProfileService.
