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. For more information, refer to the Niagara Web Launcher - Niagara Java-based Web Clients Guide PDF
