title: Reading a json file using Gson in play framework
body: <p>I'm using Play framework, I want to read a json file, I have a json file with contents similar to</p>
  <blockquote>
  <p>{&quot;columns_map&quot;:[&quot;SenderName&quot;,&quot;Message&quot;,&quot;Device&quot;,&quot;Acknowledge&quot;,&quot;Time&quot;],&quot;rows_map&quot;:{&quot;219&quot;:[&quot;mahesh&quot;,&quot;come soon&quot;,&quot;Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1&quot;,&quot;Data Inserted Successfully&quot;,&quot;&quot;]}}</p>
  <p>SenderName,Message, Device,Acknowledge,Time will be columns for JQuery datatable, rows_map will be the records, I can't feed the file directly to JQuery since i have to perform conditions and display a certain records.</p>
  </blockquote>
  <p>There will be 5 lakh records inside the file. Is it best to gson or other parser(which one please?) or create own encoder/decoder functionality
  How to parse the file so that i can feed the datatable as i wanted.</p>
