Re: Write to to resources location from another module

There is a virtual filesystem in the app that is intended to access the 
configuration files both jar based and user settings.

To my understanding of how a virtual filesystem works, you could 
similarly create your own additional virtual filesystem that overlays 
the resource directories in the jars and maps them to a folder in the 
user directory in that application filesystem. You can then write to the 
resource folders while existing content from the Jar is still accessible.

I hope this hint gets you in teh right direction
