Worklight 6.2 - Error in Mobile Browser Simulator

Question

Using Worklight 6.2

1. I deployed the application into Worklight Server
2. I open the Worklight Console and click on 'Preview'
3. I could not see the Mobile Browser Simulator; the browser only displays the index.html page of the application without the Mobile Browser Simulator.
4. There is stacktrace in the Worklight Console.
5. I am pasting a portion of the stacktrace below.

Answer 1

It is very possible that you have another instance of JVM running that are doing the same thing, perhaps you can kill the java process and try again.
