Many companies have implemented user productivity applications that work as Web applications, yet still have a terminal emulator running on the user's desktop. With Flynet Viewer, the TN5250 applications can be integrated at the browser so that the users see a single menu, and can easily switch between other web applications and the TN5250 emulation session.
IBM/Rational Host-on-Demand and Microfocus/Attachmate Reflections for the Web are two of the most popular Java-based Web terminal emulators in-use today.
Originally, Java provided a slick way to reduce the hassles of installing desktop terminal emulators while also enabling integration with in-house Web Applications through a variety of HLLAPI-derived API's.
But Oracle has withdrawn support for Java applets, making their use problematic both from a management and security perspective. What once was a slick solution is now a big PAIN and your users are the ones suffering a loss of productivity and compatibility--only Internet Explorer 11 still works with Java applets!
Other vendors may offer "HTML5 Web Terminal Emulators" but the server and network impact of these are radically different; NOT Inventu Flynet Viewer, with TrimBlock technology.
Inventu has helped many organizations, both large and small, convert from being trapped by their Java TN5250 terminal emulators -- Learn more about What You Should Look For in a TN5250 Web Terminal Emulator.
