Having some trouble reading JSON response - servlets

Question

I make an ajax request to the servlet that returns the result of a database query.
I can see with firebug the response and I want to put these results in a list (or other..) that I have already created.
I tried to read this post but it didn't help me..
Code:
this is the ajax request:
Ext.Ajax.request({
url: '/VIProject/Container',
success: function (action){alert('Lista caricata!'); console.debug(action); },
failure: function (){alert('Errore nel caricamento...');},
headers: {
'my-header': 'foo'
},
params: { action: "GETCONTAINERLIST" }
});
response from servlet(firebug):
{"message":"OK","container":[{"idOrdine":"1","numLotto":"123"},{"idOrdine":"2","numLotto":"321"},{"idOrdine":"3","numLotto":"876"}],"success":true}
list:
var listView = Ext.create('Ext.grid.Panel', {
width:425,
height:250,
id: 'lista',
collapsible:true,
title:'Simple ListView <i>(0 items selected)</i>',
store: //???
multiSelect: true,
viewConfig: {
emptyText: 'No images to display'
},
columns: [{
text: 'idOrdine',
flex: 15,
sortable: true,
dataIndex: 'idOrdine'
},{
text: 'Last Modified',
flex: 20,
sortable: true,
dataIndex: 'numLotto'
}]
});
How can I do?

Answer 1

I've modified your code to use a store:
Ext.define('MyModel', {
extend: 'Ext.data.Model',
fields: ['idOrdine', 'numLotto']
})
var listView = Ext.create('Ext.grid.Panel', {
width:425,
height:250,
id: 'lista',
collapsible:true,
title:'Simple ListView <i>(0 items selected)</i>',
store: store: {
model: MyModel,
autoLoad: true,
proxy: {
type: 'ajax',
url: '/VIProject/Container',
reader: {
type: 'json',
root: 'container'
}
}
},
multiSelect: true,
viewConfig: {
emptyText: 'No images to display'
},
columns: [{
text: 'idOrdine',
flex: 15,
sortable: true,
dataIndex: 'idOrdine'
},{
text: 'Last Modified',
flex: 20,
sortable: true,
dataIndex: 'numLotto'
}]
});

Even in this way it works:
var proxy=new Ext.data.HttpProxy({url:'/VIProject/Container'});
var reader=new Ext.data.JsonReader({},[
{name: 'idOrdine', mapping: 'idOrdine'},
{name: 'numLotto', mapping: 'numLotto'}
]);
var store=new Ext.data.Store( {
proxy:proxy,
reader:reader
});
store.load();
I tried in every way.. but i don't know what to do!
