title: Writing JSONObject into a file
body: <p>I'm using Play framework. I have a JSONObject which has a structure like the below (As in console it printed)</p>
  
  <pre><code>{
      "rows_map":{
          "220":["mahesh",
              "outfit:bmtech,app:salesreport,uuname,ffname,llname",
              "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.5",
              null
          ],
  "221":["mahesh",
              "outfit:bmtech,app:salesreport,uuname,ffname,llname",
              "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.5",
              null
          ],
  "222":["mahesh",
              "outfit:bmtech,app:salesreport,uuname,ffname,llname",
              "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.5",
              null
          ],
  "223":["mahesh",
              "outfit:bmtech,app:salesreport,uuname,ffname,llname",
              "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.5",
              null
          ]
  },
      "columns_map":["Sender",
          "Message Received",
          "Device",
          "Time"
      ]
  }
  </code></pre>
  
  <p>I want to write this JSONObject to a file. Here is the code </p>
  
  <pre><code>String path = "/var/www/html/Prj/public/CacheLayer/Incoming_Cache/CacheFileMgr.cache";
  
              ObjectOutputStream outputStream = null;
          try{
              outputStream = new ObjectOutputStream(new FileOutputStream(path));
              System.out.println("Start Writings");
                  outputStream.writeObject(object);
                  outputStream.flush();
                      outputStream.close();
            }catch (Exception e){
            System.err.println("Error: " + e);
            }
  </code></pre>
  
  <p>The above doesn't successfully writes to the file. Serialization error occurs.</p>
