Over riding a properties file?

Question

Is there a way to pass a new properties file on the command line that will over-ride a properties file embeded in the jar file?
Our deployment would otherwise involve creating multiple copies of one jar file with slightly different properties files (and this is 3rd party so I can't get the devs to change it).
Cheers,

Hmmm, I'll assign the dukes, but it wasn't a world changing answer - RTFM for dukes is a bit cheeky!
The correct answer appears to be that if we copy the properties file from the jar to the deployment directory and delete it from the original jar file, so long as we put the deployment dir in the classpath the new properties file will be picked up.
E.g.
c:\product\javalibs\myjar.jar <- Contains 'myprop.properties' on install.
Use zip to extract myprop.properties and copy it to say c:\myproject\props\
Use zip to delete myprop.properties from the jar file and include c:\myproject\props\ in your classpath.
Java will then find the properties file from the classpath when it can't find it in the jar file.
As intended you can now copy the properties file to c:\mynextproject\props and modify it then include it in that deployments classpath and you have one app install with multiple properties.
In fact no, I'm not going to award the dukes as the Jar command wouldn't even begin to help solving that lot (except arguably the extract of the props file).
Hope the above helps someone else as well as me.
