ClassLoader.getSystemResourceAsStream("Favorites.txt")


This will return you an input stream. Hope this helps.

Are you saying the exe is inside the jar?
That's simply not going to work.

When you call Runtime.exec() it lets windows make the call, but windows doesn't know how to execute something inside a jar file.

You'll need to extract the file if you want to do this.

Before making JAR it was working, but after making the jar it starts not running..

the code is below

Process process;
try{process =Runtime.getRuntime().exec("data/natives.exe");}catch(IOException _IoExc) { }

is ther any other method without extracting?
