Creat simple library for javaCard

Question

hi all.
thanks for your reading.
i use NetBean to create library. My project is very simple, just have some variables and some public methods. Now, i built and received 2 files: Mylib.Exp and Mylib.Class.
The question is: how to convert it to JAR file to import from another applet.
I use command line: jar -cvf, but it throw ex:
java.io.FileNotFoundException: mylibrary\javacard (Access is denied)
at java.io.FileOutputStream.open(Native Method)
at java.io.FileOutputStream.<init>(FileOutputStream.java:179)
at java.io.FileOutputStream.<init>(FileOutputStream.java:70)
at sun.tools.jar.Main.run(Main.java:169)
at sun.tools.jar.Main.main(Main.java:1149)
here is my simple code:
package mylibrary;
import javacard.framework.JCSystem;
public class MyLibClass {
     public byte f1 = (byte)3;
     private byte f2 = (byte)2;
     protected byte f3 = (byte)2;
     private byte f4;
public byte f5 = (byte)1;
     byte f;
     public void mPublic(byte a, byte b){
          f = (byte) (f2+f1+f3+f4+f5);
     private void m_private() {
          return;
protected void mProtected(byte a, byte b){
          f = (byte) (f2+f1+f3+f4+f5);
thanks you all

Hi,
This is not a problem with your code. Can you show the complete command you ran? It looks like you do not have permission to write to the output folder.
You should also be able to create a JAR file from NetBeans. As far as I am aware, when you build a project it will create a JAR file in the dist directory.
Cheers,
