    Default Request is not coming into my Struts 2 action method from the Extjs

    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 in 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();


    Struts.xml

    <?
    xml version="1.0" encoding="UTF-8"?>
    <!
    DOCTYPE struts PUBLIC

    <
    result name="success">admin/success.jsp</result>
    </
    action>
    </
    package>
    </
    struts>

    Action method

    public
    String getMasterTableList() {
    System.
    out.println("AdminAction.getMasterTableList @@@@@");

    List<CRUDSVO> objCRUDTableList =
    null;
    Iterator<CRUDSVO> objItr =
    null;
    CRUDSVO objCRUDSVO =
    null;
    Map<String, String> interfaceObject =
    null;
    List<Map<String, String>> interfaceArray =
    new ArrayList<Map<String, String>>();
    Map<String, List<Map<String, String>>> finalInterfaceObject =
    new HashMap<String, List<Map<String, String>>>();

    try
    {
    HttpServletResponse response = ServletActionContext.getResponse();

    objCRUDTableList =
    adminBo.getCRUDTableList();
    objItr = objCRUDTableList.iterator();

    while
    (objItr.hasNext()) {
    objCRUDSVO =
    null;
    objCRUDSVO = objItr.next();

    interfaceObject =
    new HashMap<String, String>();
    interfaceObject.put(AdminConstants.
    TABLE_NAME, objCRUDSVO.getTableName());
    interfaceObject.put(AdminConstants.
    DISPLAY_NAME, objCRUDSVO.gettableDisplayName());
    interfaceArray.add(interfaceObject);

    }

    finalInterfaceObject
    .put(AdminConstants.CRUD_DATA, interfaceArray);
    response.getWriter().write(finalInterfaceObject
    .toString());
    }
    catch (IOException e) {
    e.printStackTrace();

    }

    return
    SUCCESS;
    }


    Thanks in advance for guiding me.


    Best regards,

    Default

    Looking at the network tab in developer tools in the browser, do you see the request?
