Loading files from java jar file

Question

Hi I am stuck with following code. I would like to get files from folder but when I export project to jar file it wont work any idea?

 public String getXSDfilenames() {
        String filenames= "";
        try {
            File currDir = new File(".");
            String path = currDir.getAbsolutePath();
            path = path.substring(0, path.length()-1);

             File file = new File(path+"src\\schemaFiles");     
            String[] files = file.list(new FilenameFilter() {
                public boolean accept(File dir, String name) {
                    return name.endsWith(".xsd");
                }
            });
            if (file.exists()) {
                for (int i = 0; i < files.length; i++) {
                    System.out.println(path+"src\\schemaFiles\\"+files[i]);
                filenames = filenames + files[i] + newline;
                }
            } else {
                System.out.println("No schema files founded in default folder!");
            }
        }
         catch (Throwable e1) {
        System.out.println(e1);
        }
        return filenames;
    }

}

Your code also wouldn't work on a Unix machine. Use `getResource` instead of tying so closely to `File` with hardcoded paths. — chrylis -cautiouslyoptimistic-, Aug 23 '13 at 14:10
You generally get a better response if you define exactly what you mean by "doesn't work". What is the expected outcome and what happens instead. — Mike, Aug 24 '13 at 01:49

If you change the name of your XXX.jar file to XXX.zip, then open it in whatever Zip file utility you might have available, you can look inside the file and see 1. Whether your files are getting included in the jar at all, and if they are, 2. the actual path in which they are stored. I strongly suspect there's now src folder inside your jar.

Also, if you're NOT expecting the files to be in the jar, then you'll probably need to supply an absolute path to the files.

If they are in the jar, then check out these questions:

Yes they are included so what I need to do is only change path to jar. file and it should work? – Buteo Mausjäger Aug 23 '13 at 14:15
