I use the Worklight Developer Edition within Eclipse Juno (Eclipse BUILD id: 20120920-0800, WorklightStudioPlugin 18.104.22.16821129-1027) on top of a Windows 7 Machine.
My local server log output:
[2012-12-18 14:09:32] Worklight Server started successfully on localhost:8080 [2012-12-18 14:09:32] Activating Worklight project: HelloWorklightProject...

What can I do to resolve this problem?
