Read Java application file fom a Jar library contained in the same Java application

Question

I have created a Jar library which its initialization, capabilities, features, etc. should be customized. The problem is that I want this customization to be performed using an external XML file, so the Jar library reads that file and initializes accordingly. The scenario is the following:

I have a Java application which contains the Jar library and the config.xml file. How do I make the Jar library to read the config.xml file? An image for a better understanding:

I have been searching for hours but all I find is how to read files within the same jar file with the resources approach. Can this be done at all? If not, any good alternative out there?

How you solved this issue. I've similar issue, I made a maven library file but I need end user who use the library to customize it by adding information to .properties file in his own project? — Ayman Al-Absi, Nov 12 '14 at 21:12

You can use zip utils from java.util.zip package http://docs.oracle.com/javase/6/docs/api/java/util/zip/package-summary.html

Like here Read a file inside a Zip archive and put its content into a String in Android

I am not sure whether this question is about android since there is no android tag attached to the question – Chetan Kinger Sep 20 '12 at 09:20
I don't want to read a file contained in a jar, I want to read an external file from a jar using relative pathing. – David Escalona Ozaeta Sep 20 '12 at 09:44
David, the blue rectangle in your diagram is a jar archive, right? @bot: this code is the same on java se – zacheusz Sep 20 '12 at 12:43
@zacheusz Yup, when exported it will be an executable Jar. – David Escalona Ozaeta Sep 20 '12 at 17:11
So to read file from it you must use zip utils. Obtaining the path is trivial. – zacheusz Sep 20 '12 at 22:28
