ExtJS Reading JSON

I am trying to recreate the Editable Big Data Grid from Sencha's Kitchen Sink. I have copied the files exactly (the code is found on the right under the collapsed details window) and the only change I have made is "KitchenSink" becoming the name of my app, "FreshApp". I also copied the BigData.js, Init.js, and Order.js files from the Sencha SDK. My app builds and gives me no errors, but the JSON data does not load, giving me a blank table.

I assume this code (found at /data/BigData.js) is supposed to serve up JSON to /FreshApp/BigData:

Ext.ux.ajax.SimManager.register({
  '/FreshApp/BigData': {
    type: 'json',
    data: process([{

And I would assume this code (found at /app/store/BigData.js) is supposed to retrieve it:

proxy: {
  type: 'ajax',
  limitParam: null,
  url: '/FreshApp/BigData',
  reader: {
    type: 'json'
  }
},

When I navigate to http://localhost:1841/FreshApp/BigData, I get a 404. I have had no problems using XML, but JSON is giving me fits. Any help would be appreciated. Thanks.

Have you tried loading the json directly, without the SimManager? Put your json file somewhere on your app folder structure and point the url of the proxy to it as a relative path. Something like this:

proxy: {
  type: 'ajax',
  limitParam: null,
  url: '../resources/MyBigData.json',
  reader: {
    type: 'json'
  }
}

If this doesn't work either, and your a 100% sure, that the relative path is correct, then you should check if:

  1. the MIME-Type for Json is configured in your server
  2. you/your server has sufficient rights to access the resource folder/ the file.
