Reading content of a JAR file (at runtime)? [duplicate]

Answer 1

Here is the complete code which reads all the file contents inside the jar file.

public class ListJar {
    private static void process(InputStream input) throws IOException {
        InputStreamReader isr = new InputStreamReader(input);
        BufferedReader reader = new BufferedReader(isr);
        String line;

        while ((line = reader.readLine()) != null) {
            System.out.println(line);
        }
        reader.close();
    }

    public static void main(String arg[]) throws IOException {
        JarFile jarFile = new JarFile("/home/bathakarai/gold/click-0.15.jar");

        final Enumeration entries = jarFile.entries();
        while (entries.hasMoreElements()) {
            final JarEntry entry = entries.nextElement();
            if (entry.getName().contains(".")) {
                System.out.println("File : " + entry.getName());
                JarEntry fileEntry = jarFile.getJarEntry(entry.getName());
                InputStream input = jarFile.getInputStream(fileEntry);
                process(input);
            }
        }
    }
}
