Jar File Manifest

[hitmen]

1) Am I supposed to create a manifest file before I compile a jar file or is it the other way around?

2) when I compile my Jar file using command prompt, there is compliation error but when I run it in netbeans it works. Please refer to attachment

3) How am I supposed to pass arguments in the JarRunner class?
The JarRunner Class (The Java™ Tutorials > Deployment > Packaging Programs in JAR Files)
There is no prompt for user input.:mad:

public JarClassLoader(URL url) {
super(new URL[] { url });
this.url = url;
}

public static void main(String[] args) {
if (args.length < 1) {
usage();
}
URL url = null;
try {
url = new URL(args[0]);
} catch (MalformedURLException e) {
fatal("Invalid URL: " + args[0]);
}
// Create the class loader for the application jar file
JarClassLoader cl = new JarClassLoader(url);

manifest file can be created right from txt file with right click -> Create -> newfile.txt ) just change txt to *.mf exten.
But your manifest should contain correct path to your main class so add it manually. some like a mainpackage.mainclass...
pack jar file and create web-inf package and place your manifest to it. then place web-inf right to your jar file )
I know it seems too manually but it is quite useful )))

what is web-inf package? How do I place it "right to" my jar file? I even have problems opening it. If I extract it, I cant even edit the .MF extension.

When you build the application on NetBeans did you check the dist folder in the project folder?
