You cannot call any webservice from your browser because of security reasons so either you have to use JSONP proxy on app side or you have to enable CORS on your server side. If you are planning to build this as app then you don't have to do this, all you have to do is change security setting of your browser when you are testing.

This problem appears when i code like here:
Ext.Ajax.request({
url: 'http://api....api.php/national',
useDefaultXhrHeader: false,
success : function(response, opt) {
Ext.Msg.alert('Success', response.responseText);
},
failure : function(response, opt) {
Ext.Msg.alert('Failed', response.responseText);
}
});
Or:
var onlineStore = Ext.getStore('NationStore');
onlineStore.load();
This is screen shot about error! Thanks!

This appears to be cross domain Ajax call. Browser won't allow it by default. http://en.wikipedia.org/wiki/Same_origin_policy
You need to implement CORS http://en.wikipedia.org/wiki/Cross-origin_resource_sharing
