File path working in NetBeans but not in built JAR file - resources

Question

I am trying to copy file from classpath to user specified location. However, While running program in netbeans, file path works correctly and file gets copied but when I build a jar file and try the same, it doesnt locates source file.
URL url = getClass().getResource("utils/mount");
File file = new File(url.getPath());
this.copyEachFile(url.getPath(), "C:\\Users\\Nikhil\\Desktop\\" + mount); //this function takes in source path of file and copies it to destination path.
when I trace source path I get
/C:/Users/Nikhil/Documents/NetBeansProjects/Aroma-Installer/build/classes/aroma/installer/utils/mount
in netbeans and following in jar
/C:/Users/Nikhil/Documents/NetBeansProjects/Aroma-Installer/dist/Aroma-Installer.jar!/aroma/installer/utils/mount
When I run program in netbeans, file successfully copies but while running through jar, it says source doesnt exist.
Where is the problem?

Answer 1

Okay so I created a function and called it as follows.
this.copyFileFromJar("utils/mount", "C:\\Users\\Nikhil\\Desktop\\mount");
Definition of function is as follows.
public void copyFileFromJar(String source, String destination) throws IOException{
File dest = new File(destination);
if(!dest.exists()){
dest.createNewFile();
}
InputStream in = null;
OutputStream out = null;
try{
in = this.getClass().getResourceAsStream(source); //Important step, it returns InputStream which can be manipulated as per need.
out = new FileOutputStream(dest);
byte[] buf = new byte[1024];
int len;
while((len = in.read(buf)) > 0){
out.write(buf, 0, len);
}
JOptionPane.showMessageDialog(null, "File Successfully copied at" + dest.getAbsolutePath());
System.out.println("File Writing......" + dest.getName());
}
finally{
in.close();
out.close();
}
}
And now I am able to copy files from jar file to user specified location.
Hope this helps anybody who is looking for same kind of problem.
