I think you are not locating the configuration file struts.xml where it should be located.
According to the architecture it should be along with the com package.

Hi,I tried the select tag.but its giving error that “The requested list key ‘searchEngine’ could not be resolved as a collection/array/map/enumeration/iterator type”
I tried select tag from many sites.but all are showing this same error.is it due to not adding any plugins???
please help me….
- Mohammad Faiz February 23, 2012 at 4:39 am
  you must be using struts2-jquery-tags before using struts2 select tag. And check if your getter and setter methods for the list to be populated in select tags are properly formed in java action class. Also check whether the list object is created before the result is displayed.
```
public class SelectList extends ActionSupport
{
    private List selectList;
    public List getSelectList()
    {
       return selectList;
    }
    
    public void setSelectList(List selectList)
    {
        this.selectList=selectList;
    }

    public String execute()
    {
        selectList=new ArrayList();
        selectList.add(new Customer(1,"Arif");
        selectList.add(new Customer(2,"Shahab");
        selectList.add(new Customer(3,"Shoeb");
        return "success";
    }
}
```

Hi,
Could you post a tutorial on using cookies with struts2?
. We can read cookies using CookiesAware interface
. We can write cookies to the response by response.addCookie(cookie)
. But when it comes to re-direction from one host to another, the response looses the cookie informaiton, for example:
I am accessing http://localhost/struts/mypage, I click on some link, and if I want to be redirected to http://somesite.net/strutstutorial.zip (say if its a file download), I miss the response information. when I look at live header, it says max-age is 0 and no cookie information is available.
It would be really helpful if you could post a tutorial on this.
Thanks
- Tamil February 14, 2012 at 11:47 am
  I fixed this issue;
  1. I found that the hostname I set in cookie domain mismatch
  2. cookie name value pair string had double quotes (we have to encode)
  3. some redundant value in cookie
  good luck
ogott February 3, 2012 at 7:45 am
Hi,
First off I think all your examples are really awesome!
I noticed that you have a multi image upload example.
What I was wondering is if you have an example with columns / rows with multi form fields?
For example:
Id First Name Last Name Age
1 text box text box drop down
2 text box text box drop down
Most examples I’ve seen looking around have a edit link(with draw on single form), or delete link for each row.

Hi mkYong,
tutorial is good.I want to know select box validation(which are populated by dojo using other action) in struts2.
Priyanka November 4, 2011 at 6:59 pm
Hi,
I have implemented most of my website application. However I faced a problem in using ajax. I wanted to get some details from my DB and show it at the front end using Ajax.
I have written my ajax code (which works fine in other basic JSP application). The action that I send from my ajax code, calls the method of the action class as specified in struts.xml . new_jsp_page.jsp
However on success it will call a new jsp page. So Ajax is not achieved.
I have learnt from various sites and blogs that it is not possible to use ajax as used in normal JSP. We need to use some plugins like “dojo”
Can you tell me if it is possible to achieve ajax without using these plugins?
As of now I have created a jsp page which returns my content back to client. But I am forced to keep this jsp page out of my jsp folder as I need to restrict direct access of other jsp pages.

  Your inputs are appreciated. Thanks

    The spring framework mvc hello world example,
    located at http://www.mkyong.com/spring-mvc/spring-mvc-hello-world-example/
    has very good explanations like :
    work flow diagram,dependency etc were explained very clearly .
    but struts2 hello world example located at http://www.mkyong.com/struts2/struts-2-hello-world-example/
    does not have the explanation as in spring example.
    and one more thing, I never used Marven before, and you have explained your struts example with Marven, and spring example normally.
    Please explain the struts frame work with diagram.
