I am very new to Ext JS Framework. I am unable to understand the concepts of Ext JS (Eg., difference between JSON / JSONP / AJAX proxies with store). Please share sample projects with implementation, that would be helpful to get a complete idea of the Ext JS.

These are the server side methodologies using in my application.

Servlet for file upload
Webservice for Retrieve / Save Details of an entity (Eg. Student)
REST Service for gird components (Eg., List of students)

I need to integrate Ext JS with these kind of server side application with "POST" http method.

Added, Please share the tutorials / videos / links for understanding the concepts of Ext JS.

http://docs.sencha.com/ext-js/4-0/#! (http://docs.sencha.com/ext-js/4-0/#%21), this link only explores the API documentations. This will be helpful to understand what is what?

Thanks in Advance,

There is no JSON proxy but a JSON reader. Ajax proxy using an ajax call to retrieve data. JsonP proxy using JsonP to retrieve data. The difference for you is JsonP allows cross-origin loading (needs a special response) where Ajax won't do cross-origin loading.
