calling an Eclipse based RTC Plugin from Browser
One answer
This is more an RCP feat: https://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Forg%2Feclipse%2Fswt%2Fbrowser%2FBrowser.html
I would suggest looking for a listener, eg StatusTextListener and trigger the plugin method from there.
