Using of zip option

Question

hello everybody
i am trying to compress a few files to a *.zip package, but my code does not write anything into the file. the file is created and has the size of the files to compress but the file itself is emty.
here you see my code, please focus on the try/catch block:
public static void writeZipPackage(Collection v_packages, ZipOutputStream v_outPutStream, String v_langTwo) throws Exception     {
          Iterator iter = v_packages.iterator();
byte[] readBuffer = new byte[2156];
int bytesIn = 0;
//XML File erstellen
writeXmlLz(v_packages, v_langTwo);
          while(iter.hasNext())     {
               TranslationPackage aktPackage = (TranslationPackage)iter.next();     // aktuelles Paket
               File aktPackagePath = getDirForPackage(aktPackage.getPackageName());     // hollt die Verzeichnisstruktur f�r das aktuelle Paket
               String aktPath = aktPackagePath.toString();
               aktPath = aktPath.substring(0, (aktPath.length()-8));     // aktueller Pfad
               String aktFilename = "messages_" + v_langTwo + ".properties";     // aktueller messages File
               v_outPutStream.setMethod(ZipOutputStream.DEFLATED);     // Archivierungsmodus
               try {
                    File file = new File(aktPath, aktFilename);
                    FileInputStream fileIn = new FileInputStream(file);
                    v_outPutStream.putNextEntry(new ZipEntry(aktPath));
                    // now write the content of the file to the ZipOutputStream
     while((bytesIn = fileIn.read(readBuffer)) != -1) {
          v_outPutStream.write(readBuffer, 0, bytesIn);
     }     // end of while
     v_outPutStream.flush();
     v_outPutStream.closeEntry();
     // close the Stream                     
     fileIn.close();
               } catch (Exception e) {
                    throw new Exception(e.getMessage(), e);
               }     // end of try/catch
          }     // end of while
     }     // end of writeZipPackage
i have already looked up a few tutorials how to use the zip option in java, but it did not help. So please help me. Thank you in advance.

till now i have made it to add files that are in the
same directory, but if i add a folder structure is
not in the zip file.Wild guess: change the following:
File file = new File(aktPath, aktFilename);
FileInputStream fileIn = new FileInputStream(file);
v_outPutStream.putNextEntry(new ZipEntry(aktPath));to
File file = new File(aktPath, aktFilename);
FileInputStream fileIn = new FileInputStream(file);
v_outPutStream.putNextEntry(new ZipEntry(file.getAbsolutePath()));Probably won't change anything, but it's a bit hard a guess.
