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.
