[Hackathon Use Case] FDC3 Java API

FDC3 Java API

From Wellington

Business Problem

Some firms have existing Java desktop applications, and they want to use FDC3 to integrate with other apps that use JavaScript or other technologies.

For example, a buy-side trader using an internal Java order management system selects an order on their blotter and wants to view related analytics in an external JavaScript app provided by a broker.

OpenFin has some support for FDC3 integration for Java apps using their Interop API. However, this is vendor-specific code that isn’t the same as the JavaScript/TypeScript FDC3 API.

Ideally FINOS should have interfaces for a FDC3 Java API, which can be implemented by OpenFin or other FDC3 desktop agent vendors.

This would provide a standardized API for Java app developers to use, making it easier to switch the underlying technology that provides the FDC3 communication if required.

This is a similar approach to the FDC3 .NET API that was built by Morgan Stanley.

Expected outcome

• Create a vendor-agnostic open-source FDC3 Java API, that matches the FDC3 TypeScript API as closely as possible.
• Create an OpenFin implementation of this API using the existing OpenFin Java Adapter. This may be a partial implementation if some features aren’t currently supported by OpenFin.
• Demonstrate that we can send FDC3 context or intents from a Java to JavaScript app using this library.

Useful apps, systems, projects, technologies, libraries and datasets

• Java app (Swing, JavaFX, or other UI technology)
• FDC3 JavaScript app (can use FDC3 Workbench or similar example app for POC)
• OpenFin Java Adapter
