How to generate APDU to load a cap file?

Question

Below is a code to load a cap that I got here.
public byte[] readJar(File file) throws IOException {
          int BLOCK_SIZE1;
          String[] xCaps;
          if(installDescriptor){
               xCaps = iCapsWD;
          }else{
               xCaps = iCapsWoD;
          JarFile jf = new JarFile(file);
          Enumeration e = jf.entries();
          byte[] result = new byte[(int)file.length()];
          int size = 0;
          int dsize = 0;
          JarEntry je;
          boolean found;
          InputStream is;
          //byte[] temp;
          for (int i = 0; i<xCaps.length; i++){
               found = false;
               e = jf.entries();
               System.out.println("searching: "+xCaps);
               while (e.hasMoreElements()){
                    je = (JarEntry)e.nextElement();
                    //System.out.println("component:"+je.getName());
                    if(je.getName().endsWith(xCaps[i])){
                         found = true;
                         is = jf.getInputStream(je);
                         int dim = (int)je.getSize();
                         //temp=new byte[dim];
                         System.out.println("found cap to install: "+xCaps[i]+" of length:"+dim);
                         try{
                              //int dim = is.available();
                              //is.read(temp);
                              //printApdu(temp);
                              is.read(result, size, dim);
                         }catch (Exception ex){
                              ex.printStackTrace();
                              System.exit( -1);
                         if(i==0){
                              BLOCK_SIZE1 = dim+4;
                         }else if(i==1){//analyze directory.cap
                              int component;
                              int ddim;
                              for (int h = 3; h<25; h += 2){
                                   component = (int)Math.floor((h-3)/2)+1;
                                   if(component==11&& !installDescriptor){//elimino descriptor da directory
                                        result[size+h] = 0;
                                        result[size+h+1] = 0;
                                   ddim = ((result[size+h]<<8)+result[size+h+1]);
                                   System.out.println("component size with tag: ["+component+"] "+ddim);
                                   dsize += ddim;
                         size += dim;
                         break;
               if( !found){
                    if(i==3||i==7||i==10){
                         System.out.println("Not found cap component for optional installing: "+xCaps[i]);
                    }else{
                         System.out.println("Critical error: Not found cap component necessary for install:"+xCaps[i]);
                         System.exit( -1);
          byte[] fresult = new byte[size];
          System.arraycopy(result, 0, fresult, 0, size);
          FileOutputStream fo = new FileOutputStream("pcapdump.cap");
          fo.write(result);
          System.out.println("size="+size+", according to directory:"+dsize);
          return fresult;
I open the result file of this program called "pcapdump.cap".
However, when I compare APDU generated by Tool and APDU
generated by this program , they are slightly different.
I wonder why these 2 APDU results are different.
Can anyone help me to corrent above code?
Please~

Please read the "Java Card Development Kit User&#8217;s Guide" Chapter 11. Using the Installer. There you find a detailed description how to install a java card applet.
The JC-dev User's Guid comes as HTML & PDF document with the Java Card development Kit - subdirectory "doc".
