java - Runnable jar not reading file correctly -

i use intellij idea community edition. when run game through ide, works properly. export runnable jar, , acts if can't find map text file. looked through jar winrar , found map file there in correct place.

this how lines map file:

list<string> filelines = new arraylist<>(); try (bufferedreader br = new bufferedreader(new inputstreamreader(         game.class.getresourceasstream("resources/" + file)))) {     string line;     while ((line = br.readline()) != null)         filelines.add(line); } catch (exception e) {     logger.log("could not find map file " + file + "!", logger.loglevel.severe); } 

that code start of method map.loadmap(string file).
how use it:

map map = map.loadmap("test.map"); map.init(); 

the jar file works program when running in ide when comment 2 lines out. isn't map.init() isn't working, map.loadmap() (i debugged little). problems?

edit

example map file: http://pastebin.com/rmhs1xzb

• first line: name
• second , third lines: width , height
• rest: tiles (0 grass, 1 wall)
