Zipping byte array in memory (java snippet)

[Former Member]

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.putNextEntry(zipentry);

                                                                zipfile.write("Zipped content".getBytes());

                                                                zipfile.close();

                                                      } catch(IOException e) {

                                                                e.printStackTrace();

                                                      }

byte[] result = bos.toByteArray();
