Hello,

nl.company.data.file1
nl.company.data.file2

and build in data.jar

In another java program I want to access these files and read the content
from the jar file 'data.jar'

How do I do that

Files in the class path and in particular in jar files in the class
path are called "resources" in java. Look up Class.getResource() and
ClassLoader.getResource().

You read with a resource. If you have a nested jar, you have to
unpack the jar and then read it as a file. Alternatively, you unpack
the jar so there is one big jar with no nesting. Then you get at
everything as a resource.

See http://mindprod.com/jgloss/resource.html

out resources.)
