Struts 2 jQuery Autocompleter with select box doesn't populate any values

I've used the Struts 2 jQuery autocompleter for my Struts 2 application.

Here is my code:

JSP:

 <s:form id="frm_demo" theme="simple" action="ManagersAutoCompleter1">
        <s:url var="remoteurl" action="test" />
    <sj:autocompleter href="%{remoteurl}" id="echo3" name="echo"
        list="itemList" listKey="id" listValue="name" emptyOption="true"
        headerKey="-1" headerValue="Please Select a Language" selectBox="true" />

        <s:submit value="submit" />
    </s:form>
      

struts.xml:

<action name="test" class="test.TestAction" method="populate">
  <result type="json">
  </result>
</action>

Action Class:

 public String populate() throws Exception {
        
        itemList = new ArrayList<ListValue>();
        itemList.add(new ListValue("Php", "Php"));
        itemList.add(new ListValue("Java", "Java"));
        itemList.add(new ListValue("Mysl", "Mysl"));
        return SUCCESS;
    } //getter setter for itemList

List Class:

public class ListValue {
    private String id;
    private String name;

    public ListValue(String id, String name) {
        this.id = id;
        this.name = name;
    } //getter setter methods

But, this Struts2 jQuery autocompleter is not working. It doesn't populate any values.

Do this one

<s:url id="remoteurl" action="test"/>
<sj:select 
     id="customersjsonlstid" 
     name="echo"
     label="Handle a List"
     href="%{remoteurl}" 
     list="itemList"
     listValue="name" 
     listKey="id" 
     autocomplete="true"  
     loadMinimumCount="2" 
     id="echo3"/>

Instead of this:

<sj:autocompleter href="%{remoteurl}" id="echo3" name="echo"
list="itemList" listKey="id" listValue="name" emptyOption="true"
headerKey="-1" headerValue="Please Select a Language" selectBox="true" />

And make sure you are returning the list from your action class. To check this, do it with your IDE debugger or System.out.print etc.

ex...


    -------------
    ------------
    itemList.add(new ListValue("Mysl", "Mysl") );
    System.out.println("Size of my list="+itemList.size());
    return SUCCESS;
}

And also you should define getter & setters in your action class

private List itemList; 
    public List getItemList() {
    return itemList;
} 

public void setItemList(List itemList) {
    this.itemList = itemList;
}
