title: Why Javacard prevent uploading different in AID .cap files of a single javacard program?
body: <p>This is a simple javacard program (It do nothing!) :</p>
  <pre><code>package testAID;
  
  import javacard.framework.APDU;
  import javacard.framework.Applet;
  import javacard.framework.ISOException;
  
  public class TestAID extends Applet {
  
      private TestAID() {
      }
  
      public static void install(byte bArray[], short bOffset, byte bLength)
              throws ISOException {
          new TestAID().register();
      }
  
      public void process(APDU arg0) throws ISOException {
          // TODO Auto-generated method stub
      }
  
  }
  </code></pre>
  <p>I convert it to three <em>.cap</em> file with different AIDs as follows:</p>
  <ol>
  <li>File A:  PkgAID=<code>0000000000</code> &amp; AppAID=<code>000000000011</code></li>
  <li>File B:  PkgAID=<code>0000000000</code> &amp; AppAID=<code>000000000022</code></li>
  <li>File C:  PkgAID=<code>000000000011</code> &amp; AppAID=<code>00000000001111</code></li>
  </ol>
  <p>As you see above, <strong>File A</strong> and <strong>File B</strong> are different only in <strong>AppAID</strong>. And <strong>PkgAID</strong> of <strong>File C</strong> is equal to <strong>AppAID</strong> of <strong>File A</strong>.</p>
  <p>Now I want to upload this files on my <strong>NXP JCOP v2.4.2 r3</strong> smart card. First of all, let see the contents:</p>
  <pre><code>GP: gp -list

  <p>OK, There is only the SD.</p>
  <p>Step1: Installing <strong>File A</strong> :</p>

  <p>Failed in installing again and <code>gp -list</code> command returns the same previous results.</p>
  <p><strong>Questions:</strong></p>
  <p>1-What is the origin of first error? Is it illegal to upload two <code>.cap</code> file that are different in AID and have an equal PkgAID in two step?</p>
  <p>2-What is the origin of second error? It returns that</p>
  <blockquote>
  <p>Package with AID 000000000011 is already present on card</p>
  </blockquote>
  <p>But there is not! It is an applet AID, not Package AID.</p>
  <p>3-Are the gp prevented to install this applets or the origin of error is JCRE?</p>
  <hr />
  <p>As I was thought it the <strong>GP</strong> tool that limited me in installing, I tried <strong>JCManager</strong> also. The result are different!</p>
  <p>First of all I delete everything except SD:</p>
