compress a directory and download it

[debutant_ISC]

Hello,
I created a function that compresses a directory but I don't know how to manage the output stream in order to give the possibility to the user to download this directory! Isomorphic, have you any idea Please ?

here is my code :

public String  performExport(javax.servlet.http.HttpServletRequest request,javax.servlet.http.HttpServletResponse response, 
			String p_sBook_ID,  String p_sUser_ID, String p_sFormat) {
	
	String sReturn = _Return_OK;
			try {
			
                  writeServerDebug("performExport(req,resp,'" + p_sBook_ID + "'," + p_sUser_ID + "," + p_sFormat + "):start");

                  // ====================================================
                  // = Get the template directory
                  // ====================================================
                  FilerManager myFiler = new FilerManager();
                  String sInputPath = myFiler.getDirectory(
                  FilerManager.DirectoryKind_Users, true);
                 
                  // ====================================================
                  // = Working variables JDBC objects.
                  // ====================================================
                  Connection con = null;
                   Statement stmt = null;
                   ResultSet rs = null;
                   String SQL = "";
                 
                  try {
                        writeServerDebug("performExport >> START");
                        // ---------------------------------------------------------
                        // - Establish the connection.
                        // ---------------------------------------------------------
                        con = get_RepositoryBridge().getSourceDataBaseConnection();
                  } catch (Exception ex) {
                        sReturn = Repository._Return_KO;
                  }

                  HashMap<String, Object> _hCacheBook = new HashMap<String, Object>();
                  try {
                        int iSrcCount = get_RepositoryBridge().cacheQueryData(
                                   "SELECT TOP(1) * FROM " + Books.Table + " WHERE "
                                               + Books.Column_IDNum + "=" + p_sBook_ID,
                                   _hCacheBook, "DataBase_Source");
                        int iColCount = (Integer) (_hCacheBook.get("SQL_ColumnCount"));
                        String sColDesc = (String) (_hCacheBook.get("SQL_ColumnDesc"));
                        String sColValues = (String) (_hCacheBook
                                   .get("SQL_ColumnValues"));

                        writeServerDebug("performExport:iColCount=" + iColCount);
                        writeServerDebug("performExport:sColDesc=" + sColDesc);
                        writeServerDebug("performExport:sColValues=" + sColValues);

                        int nbrCol = (Integer) (_hCacheBook.get("SQL_ColumnCount"));
						
						ZipOutputStream objx = this.CreatXml(nbrCol, 1, _hCacheBook);
                        
                        response.setHeader("Content-disposition","attachment;filename=\testJS.zip\"");  
                        String sContentType = "application/vnd.ms-objx";  
                        response.setContentType(sContentType);
                        ServletOutputStream outStream = response.getOutputStream();
                        
                       //the problem is here ! I must add a statement to send the compressed directory to the client!
                        sortie.close();
                        outStream.flush();
                        outStream.close();
                        }

                  catch (Exception ex) {
                        System.out.println("I AM IN THE EXCEPTION :");
                        ex.printStackTrace();
                  }
                   
	}
			catch (Exception e) {
                writeServerDebug("ERROR:" + e.getLocalizedMessage());
                sReturn = Repository._Return_KO;
          }
            return sReturn;
      }

Thank you i've seen it.
But i want to download a zip file and the problem is that this type of file is zipToutStream and he does not have a function to write like write (OutputStream )
