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();

List<CRUDSVO> objCRUDTableList =

Map<String, List<Map<String, String>>> finalInterfaceObject =

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,
