Tridium Niagara N4 WebBrowser Object Fails to Render Web Site

Tridium Niagara N4 WebBrowser Object Fails to Render Web Site

Issue

When trying to embed a website in an N4 Px view, the site renders in Workbench but not in most browsers displaying this error in the browser's developer console;

Product Line

TAC IA Series

Environment

  • I/A Series N4 Workbench
  • Web Browsers, Chrome, Firefox, Edge, Internet Explorer

Cause

Most major browsers no longer support NPAPI/Java plugins.  Oracle has stated they would remove it in JDK 9  and from Java entirely.  The N4 WebBrowser object under the workbench pallet requires Java to work correctly.  That is why it only works in the Workbench environment, Internet Explorer, and older Oracle Java platforms.

Resolution

When using the WebBrowser object in Niagara N4.

Viewing in the Browser Preview Mode or in an actual browser that doesn't support the Java plugin, the embedded site will not render.

The only solution is to use Internet Explorer or the  Web Launcher application detailed in the attached document to view the Px.
