Can you post relevant code?

 

[hatzisn]

It is a web app by @Erel. I repost it here for not making you search for it.

 

[hatzisn]

Beside my response I also noticed that you will have to copy yourself the "www" folder from "Objects" folder to the "Objects/temp/build/bin".

 

[Erel]

The current jServer library + jetty are not compatible with the standalone packager.
