Zipping byte array in memory (java snippet)

In case you need to zip some data, for sending to the client on the fly without intermediary file creation that’s simple as piece of cake:

ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
                                                      ZipOutputStream zipfile = new ZipOutputStream(bos);
                                                      ZipEntry zipentry = new ZipEntry("packedFileName");
                                                      try {
                                                                zipfile.write("Zipped content".getBytes());
                                                      } catch(IOException e) {
byte[] result = bos.toByteArray();

Best wishes,
