Product Overview
Flynet Viewer Studio UX (User Experience) is a No/Low code platform that allows you to reshape how you interact with your Mainframe, iSeries, Unix, VMS or MultiValue system, changing green screen user experiences into modern interfaces that are delivered over the web to any device without client side software.
This gives you the freedom to adapt and evolve business processes, quickly realising new efficiencies and gaining instant ROI and tactical advantages that are simply not available elsewhere, what’s more, this can be done by a super user.
Flynet Viewer Studio UX is the low risk high reward answer to Mainframe, iSeries, AIX, Unix, VMS or MultiValue system modernisation and migration strategies. Flynet Studio decouples compelling events like modernisation, mobile strategy, cloud and virtualisation from the need to migrate entire heritage systems in one go. For compatible client browsers see “System Requirements for Client Deployment”.
Product Requirements
Flynet Viewer UX server requires Microsoft Windows Server (2008, 2008 R2, 2012, 2012 R2, 2016, 2019, 2022, 2025) and in the cloud on Azure, Oracle Cloud and Amazon). The minimum hardware specification required for respective versions of Microsoft Windows Server will more than adequately provision for the load created by the Flynet Viewer UX Server. The Flynet Viewer UX Server runs as a Windows Service and requires Microsoft IIS (Internet Information Services) to be running.
The Flynet Viewer Studio UX web browser based responsive GUI is largely platform agnostic, providing the client with an interface that is suitable to the device being used. On a desktop or thin client a conventional interface is produced, on a tablet or mobile device an appropriately scaled responsive interface is delivered. On a device that uses a capacitive screen a touch interface is enabled and delivered.
The Flynet Viewer Studio UX GUI will run on the following browsers:
• Microsoft Internet Explorer 6 and above versions (backward compatible to 2001)
• Microsoft Edge
• Apple Safari
• Mozilla Firefox
• Google Chrome
• Opera
NOTE: There will be wizard migration pathway for Flynet Viewer® Studio UX projects on to the Jubilant® Studio UX emulation core server available in late 2026, making migrations for existing studio project owners largely seamless.
Extensible with API’s and Access Points
Flynet Viewer Studio UX delivers modern GUI interfaces to terminal applications by creating an open and accessible .Net web application, in the MVC N-Tier style. When opened in Visual Studio .Net the Flynet Viewer Web Application is completely editable and can be extended and adapted to suite an infinite number of scenarios. Flynet Viewer Studio also ships with a Visual Studio .Net plug in allowing developers to natively use Flynet Viewer features whilst inside Visual Studio.
Any coding changes made to the Flynet Viewer Studio web application with Visual Studio .Net can be re-integrated into the Flynet Viewer Studio UX environment, allowing a non-developer to continue building the application whilst honouring the changes made by the developer.
Jubilant Technical Overview
The Jubilant Server will connect to virtually any system that uses a form based or character based terminal connection protocol. On the rare occasion that Jubilant encounters a previously un-provisioned protocol it generally takes around 2-3 days to assimilate the new protocol to full compliance within the Jubilant application. Supported systems include:
- IBM Mainframes - TN3270
- AS400 / iSeries / IBM i - TN5250
- UNIX / Linux / IBM P AIX, VT100, VT220, VT320, VT-420, SCO ANSI, ADDS ViewPoint, Wyse 50, Wyse 60
- DEC-VMS / OpenVMS - VT100, VT220, VT320, VT420
- Tandem Nonstop - TN3270
- Dell UNIKIX - TN3270
- Pick / MultiValue - ADDS ViewPoint, VT220, SCO ANSI, Wyse 50, Wyse 60, AccuTerm
Browsers
Jubilant TE emulation will run on the following browsers:
- Apple Safari
- Microsoft Internet Explorer 11
- Microsoft Edge
- Mozilla Firefox
- Google Chrome
Supported Devices
Jubilant Terminal Emulator will run on any device regardless of operating system, all that is required is one of the aforementioned web browsers to be present. Depending on the size and the interface being used Jubilant will automatically resize and rescale the interface to suit.
If a capacitive (touch screen) interface is being used Jubilant will provide full touch support automatically converting appropriate objects for touch use, similarly pinch to zoom and other device native expectations are accommodated and delivered out of the box.
Server Information
Jubilant is a high performance server based web delivered terminal emulation application optimized for use in Cloud, mobile and distributed architectures. The Jubilant Server code was never part of a desktop terminal emulation solution; from its origins it was designed to be a highly efficient multi-threaded server side core service. This means that Jubilant can support more concurrent sessions on any given server configuration than any other browser delivered emulation solution.
The Jubilant Core server runs as a Windows Service (and Linux Q3 2026), compatible with Windows Server 2016, 2019, 2022, 2025 and hydratable in the cloud on Azure, Oracle Cloud and Amazon, Google. The Core architecture was designed to be highly performant, with a minimum specification single server (as specified by the server operating system provider) capable of serving thousands of Jubilant sessions.
Terminal Emulation API
You have the option of extending your terminal emulation experience using JavaScript. An API gives you access to screen read/writes. You can also access the emulation server-side using various Flynet Viewer APIs for .NET, COM/Win32 and Javascript.
Full Function Administration Application
All host definitions and properties are created and managed with the Administration App.
In addition, easy access to the Trace Viewer and original Screen Recording App is provided with menu options.
- Administration App Features:
- Configure new host connections and manage existing ones
- Configure Service Settings
- Launch Trace Viewer, Screen Recorder and Screen Recordings Viewer
- View Session Status for a configurable range
- Start and Stop Sessions
- View a Session in a Terminal Emulation Window - Can interact with the session
Configuration
- Central configuration allows the system administrator to tailor the user environment with keyboard mapping, fonts, user-specific LU or device names, colour/attribute mapping, toolbar functions, customizable session descriptions and more.
- Text-based configuration files allowing administrators to easily find and edit entries in the configuration files either manually or programmatically.
- Multiple User Configurations
- Provides dynamic device name/logical unit (LU) assignments based on log-in, ensuring users always get the correct display and printer sessions. Jubilant supports completely custom configurations assigned on a group or user basis, the number and types of sessions, and specific device or LU assignments.
Taskbar Notification Icon and Actions
Included with the Emulation Service is a handy applet that runs in the Taskbar Notification area. It provides status information on service starts, stops and restarts. In addition, it provides convenient menu items for launching various utilities as well as starting, stopping and restarting the service.
Security
Jubilant can be secured to the highest level supported by the host web Server environment, examples including Windows IIS and Apache, are generally accepted to be securable to industry standards accepted for banking and defence. This includes the latest level of SSL/TLS up to 1.3, more commonly 1.2, any tertiary add-on or encryption, 2 Factor authentication, physical tokens or dongles can all be added on via our Security API.
All Jubilant communications made between the server and host are made over a telnet connection secured by a SSL/TLS wrapper. All Jubilant communications made between the application server and the client are primarily conducted using Web Sockets and where this is not supported HTTPs is used.
Jubilant provides Multi factor support, allowing you to integrate your terminal emulation application more seamlessly into your existing or emerging centrally authenticated stack of enterprise applications. Jubilant’s security API provides the capability to integrate with any bespoke or of the shelf multi factor or federated identity environment.
Jubilant makes single sign on to your mainframe practical, secure and easy to do. Using either a secure vault, encrypted store or encrypted access to an LDAP source.
Jubilant supports:
- Supports Secure Sockets Layer (older SSL up to v3.0 and TLS up to v1.3) encryption.
- Provides SSL authentication using digital client certificates, user generated as well as third party. Standard authentication technology is built into Jubilant.
- FIPS 140-2 Validated Cryptographic Module.
- Supports NT domain authentication / Active Directory / Azure Directory authentication.
