Unlock Your Investment in Legacy Systems

Key business data is often locked behind green screens. Jubilant WS lets that data freely interact with and feed other business systems and end users — increasing the availability, timeliness, and integrity of the information your organization runs on.

Two variants, every source

The Legacy Applications (LA) variant creates web service connections directly to green-screen data. The Database (dB) variant connects directly to any database repository — so legacy and contemporary data integrate side by side.

Full CRUD, REST and SOAP

Build full Create, Read, Update, and Delete standards-based web services in minutes — RESTful (XML and JSON), SOAP (XML), and even binary services.

Robust and fully editable

Generated services cater for edge cases not commonly encountered, maintaining a high-availability service. Output is fully editable in your favored IDE, and the generation templates are editable too.

A supported migration pathway

A wizard migration pathway for Flynet Viewer Studio WS projects onto the Jubilant Studio WS emulation core server arrives in Q3 2026, making migrations for existing Studio project owners largely seamless.

Since 1995, Flynet has been empowering global businesses with our award-winning, secure web-based terminal emulation solutions

This was an extremely quick process that enabled us to unlock the agility of an SOA architecture but built in a brown field setting”

David Camen Senior PM, Grange, Garett and Olson
