JAR file updating project config file error. Help needed!

Question

Hi all,
I got a problem when I want to use an existed jar file. There is a method called setConfig which can read and update the properties inside a property file which will be located inside the deployed jar file. But when the other project want to use this jar file. It causes the following error:
Property 'configfile' threw exception; nested exception is java.lang.IllegalArgumentException: URI is not hierarchical
The code might cause this error is like:
String temp = configfile.substring(CLASSPATH_IND.length()).trim();
URL url = BaseConfigureFactory.class.getClassLoader().getResource(temp);
try {
tempcfg = (new File(url.toURI())).getAbsolutePath();
} catch(URISyntaxException use) {
throw new IllegalArgumentException(use);
It seems like the url is wrong so that the program can not find the configfile. Does anyone give some suggestions? Thanks

I have all of e.printStackTrack( ) in my try - catch block. But i also think the blank screen appears because the class can not find my resources. Maybe it's my fault, because i create by hand a folder name "res" in project folder, then put all my resource in this folder. And in Eclipse when i try to get these resource, i wrote something like this:
     Image robot1N, robot1E, robot1S, robot1W;
     private void initResources() {               
          try {               
               String sb = "car1";
               robot1N = ImageIO.read(new File("res\\img\\unit\\" + sb +"_N.png"));
               robot1E = ImageIO.read(new File("res\\img\\unit\\" + sb +"_E.png"));
               robot1S = ImageIO.read(new File("res\\img\\unit\\" + sb +"_S.png"));
               robot1W = ImageIO.read(new File("res\\img\\unit\\" + sb +"_W.png"));
          catch(Exception e) {
               e.printStackTrace();
     }Maybe the string of path to resource is right in Eclipse but wrong in Window?
