Reference file inside jar

I'll try to get back to that later. Also, if I didn't stress it properly earlier, with this approach the resource file that you're trying to read from must be in the same directory in the jar file as this class. This is inferred by the getClass. Also, I haven't looked at it in a while, but I think you can just call the is. Here's one more example of how to do this, this time using some code from a current Scala project:. Although the code shown is Scala, I think you can see that you can use this approach to read the file as a java.

You indeed have to use forward slashes, even on Windows. That implies that you cannot use File. This is the only solution I was able to get to work, and I was working on this for hours.

I've got a class that I would like to work with both, a folder on the outside in case I want to change some parameter of the config file and a JAR that hides the implementation configuration files to the user like a distributable JAR to all people.

So the class just receives a PATH to a file the config file. Then you should probably have that class deal with an input stream, which you can get from either source. Yes, I know.
