copied!<p>I think you might be hitting a subtle issue with <code>$.post()</code> when the data is an object. It gets converted to a string, but not to a JSON string - rather, it is used as a set of key-value pairs for building a <code>application/x-www-form-urlencoded</code> string.</p> <p>Another issue with <code>$.post()</code> is that it always sends a content-type header of <code>application/x-www-form-urlencoded; charset=UTF-8</code>. This might be the reason why the server is crashing: it's expecting JSON, but the content-type is <code>application/x-www-form-urlencoded</code>. To fix this we can use the more general <code>$.ajax()</code> which has more options.</p> <p>Try this:</p> <pre><code>$.getJSON('/assets/appconf/db_trial.json', function(firstData) { $.ajax({ type: "POST", url: '/createDBJSON', data: JSON.stringify(firstData), // send JSON representation contentType: 'application/json; charset=utf-8', // set correct content-type header success: function(secondData) {window.alert(secondData);} }); }); </code></pre> <p>We could also try another method which never bothers to convert the first json response into an object and then back into a json string, instead just keep it as text the whole time:</p> <pre><code>$.ajax({ dataType: "text", // parse response only as text url: '/assets/appconf/db_trial.json', success: function(jsonString) { $.ajax({ type: "POST", url: '/createDBJSON', data: jsonString, // jsonString is already a json string contentType: 'application/json; charset=utf-8', // set correct content-type header success: function(secondData) {window.alert(secondData);} }); } }); </code></pre> <p>Please try both!</p> <p>But I still recommend fixing your back-end so the data doesn't pass through the client for no reason! I think Play Framework 2 includes Jackson for JSON manipulation, so you just need to import the right classes, and search the internet to learn how to read JSON files with the Jackson library.</p>
