I have a problem with the web emulator of worklight 6.2.0.
I have publicated an application with environment android and iphone, when i click in link "Preview as Common Resources" he it works perfect open the web page. But i click in android or iphone open the page with "Context Root Not Found"
I cannot confirm this.
Try two additional things:
When the failure occurs, also check for errors in Eclipse > Console view > Worklight Development Server
