VWA serves 3270 screens as standard HTML webpages with 3270 Terminal Emulation (TE) ergonomics over encrypted HTTPS connections to plugin-free web browsers. It is an attractive modernization alternative for TN3270 emulators. TN3270 users instantly retrieve the 3270 TE interface that they are familiar with.
VWA doesn’t rely on distributed (typically Java or HLLAPI) clients or plugins, or middle-tier servers. With VWA, the web browser is the 3270 TE client. Consequently:
- VWA works instantly with any web-enabled device regardless of technology: from traditional Windows PC workstations to Apple, Android, or Chrome mobile devices.
- VWA eliminates the costly support required with distributed TN3270 applets and plugins. With VWA, there is nothing to support outside the host: the administration and support are centralized on the host.
- VWA eliminates the security exposure associated with distributed Java applets – which must be regularly updated to patch new security exposures – and with the Java plugin – which Oracle deprecated early 2016. With VWA, the host regains full control of access to its assets.
