Question

I have a jar file with properties configuration file.

when I run it in Netbeans everything works as it should.

but when I run it in a cmd – the properties file is not found.

why?

Answer 1

It depends on how you’re loading your properties file.
Consider to load your properties with the help of:

InputStream in = getClass().getResourceAsStream("/log4j.properties");

and then use Properties.load(in)

This should handle the situation when the properties file physically resides in the jar
Good Luck!
