action code

A Sabre host command prefix, or any variation of a host command prefix, for example, HOT. A Red App can send a command prefix when it calls SRWRuntime synchronous service, notify an Event Listener about a command prefix, or register an action_code in an Event Listener.

Activator class

An Activator class is a Java class that controls the life cycle of a plug-in. This class triggers the actions on startup and shutdown, which makes an Activator the best place to allocate and release the resources that a plug-in uses.

application launcher bar

The horizontal menu bar underneath the main menu bar on Sabre Red 360

The application launcher bar has menus that organize applications into the types of tasks that end-users can perform. These menus are Tools, Community, and Admin.

The menu contributions on the launcher bar are intended solely to open Red Apps that run in editors.

application side bar

The vertical panel that contains menu entries on Sabre Red 360

The menu entries open a view that complements the capabilities of another plug-in that is running in an editor.



The valid digital certificate of the provider of the Red App

This file is the actual certificate that a developer used to sign the jar files in a Red App bundle. A developer includes this file in the root of a Red App bundle ZIP file.

A properties file with important metadata about the Red App

A Red App developer creates this file and includes it in the root of a Red App bundle ZIP file.

company name

The provider of a Red App

This may also be called a provider name. The Sabre Red App certified developer application includes a company name. For Red Apps that are deployed to Sabre Red 360, this name also appears on the GUI and it is used in certain files in a plug-in project.

dependent plug-in in a Red App bundle

Plug-ins that are either libraries, or plug-ins with minor functionality or business logic

Dependent plug-ins cannot use or include communications services. Red App developers create dependent plug-ins and may also use dependencies that third parties create.


A tab on the Sabre Red 360 GUI

An editor is a basic building block for a plug-in project. Red Apps that are based on a variety of technologies can run within a tab, for example web apps.


The occurrence of a condition for which Red Apps and other components of Sabre Red 360 can register as listeners

When the condition for an event is met, the event source (the component where the event occurred) creates an event object and publishes it to SRWRuntime. SRWRuntime then dispatches the event to all the registered listeners. All event processing is asynchronous, where SRWRuntime calls the listener, but it does not block for a response from the listener. A Red App executes some functionality when an event is raised.

Event ID

The name of an Event ID that a Red App publishes. Other Red Apps can register EventListeners for this Event ID.


For Red Apps, a class that registers for a specific set of events and is notified when the specific event is triggered

All EventListeners implement the IEventListener interface. The IEvent interface defines the methods that are required for an Event class.

Each Red App that generates a set of events defines the list of events and assigns an Event ID to each event, along with all other attributes. The Event ID uniquely identifies the Event, including the source. The Bus uses the event to notify listeners that are registered for the event.

extension point

A function point that other plug-ins can invoke through standardized interfaces

An extension point consists of elements and properties.

horizontal view

A view or application window that is oriented horizontally in Sabre Red 360

insertion point

The location of a menu entry on a sub-menu of any Sabre Red 360 main menu

JavaScript bridge (Java-to-JavaScript bridge)

The JavaScript bridge (JS bridge) enables a Red App to register for ISRWCommunication functionality by using a JavaScript function named the same as a service it calls. The JavaScript bridge lets Red Apps use the ISRWCommunication services to access other SRWRuntime functionality and access OSGi whitelisted services. This JS bridge exposes only a subset of OSGi services, referred to as whitelisted services.

You must use the default browser components for an editor or view to use OSGi communications services.

With the JS bridge, you can call any whitelisted OSGi service and you can register your own service to intercept a communication on the Bus.

main menu contribution

A menu entry on a sub-menu of the main menu bar of Sabre Red 360

main Red App plug-in

Plug-in ID

A unique identifier of a plug-in project within Sabre Red 360 and within Eclipse

For Eclipse and Sabre, it is common practice to use the top-level Java package for the plug-in project ID. The ID consists of lowercase letters.

The main Red App Plug-in ID has the following format:



com.yourcompany represents the reverse domain name of the provider of the Red App.

The last part is the Red App name

Dependent Plug-in IDs are the top level Java package. They may be anything that describes their purpose. They may also be third party jars. The format is
