System.out.println(" post 78 myJsonData: "+myJsonData);

System.out.println(" length 78 myJsonData: "+myJsonData[0]);

// processRequest(request, response);

ArrayList<String> listdata = new ArrayList<String>();

JSONArray jArray = null;

try {

jArray = new JSONArray(myJsonData);

} catch (JSONException ex) {

Logger.getLogger(placeOrderServlet.class.getName()).log(Level.SEVERE, null, ex);

}

System.out.println("***** jArray "+jArray);

System.out.println("*length**** jArray "+jArray.length());
