Request is not coming into my action method from the Extjs

[Rout, Biswajit]

Hello All,
We are doing one development activity based on Struts 2 + Spring 3 + Spring 
JDBC Template + Extjs 4.1
I want my Combo box to be getting populated with dynamic data fetched from the 
DB. However when I am running, I can see it is not at all entering into my 
action method (Not even printing the SOP in the WLS console).
I am assuming something wrong in my struts.xml or in the js file.



Please find the list of files

admin.js that is Extjs 4.1 technology (only combo box part code)
        Ext.define('MyNamespace.StoreModel', {
                extend: 'Ext.data.Model',
                fields: [
                         {name:'tablename'},
                         {name:'displayName'}]
        });

        var crudComboStore = Ext.create('Ext.data.Store', {
                model: 'MyNamespace.StoreModel',
                proxy : {
                        type :'ajax',
                        url  : 'http://localhost:7001/3pd/adminProcess.action',
                        reader : {
                        type : 'json',
                        root : 'crudData'
                    }
                }
        });
        crudComboStore.load();

                } catch (IOException e) {

                }
                return SUCCESS;
        }

Thanks in advance for guiding me.
