Jar fucking files

Hey /prog/ I am pretty pissed because I spent a large amount of effort to research and create a program that automatically updates an html page on my server. I made a java program in eclipse that reads from a file trims it and updates another file every 36 seconds. It works like a dream until I tried to execute it inside my apache folder as a jar file. Anyone here know what the fuck I did wrong? I would really appreciate if I could put this behind me. I checked all of the permissions and they are set at a dangerous 777 mode for debugging so that is not the problem. I through all exceptions so I have no feedback. Also I got compile "warnings" when I exported the jar. Very FUCKING vague java

So problem solved thanks to you geniuses. You can work with buffered reader and writer outside your working directory. Sweetness. Keep hating/trolling in your basements As I am winning
