Struts2 autocompleter

[Salvatore De Giorgi]

Hi all,

I have a problem with an autocomplete field. Unfortunately, I'm starting to use struts right now, but I have to complete this task in a couple of days.
I have a web application based on struts2, with a graphic template based on the bootstrap. For the persistence, the web application uses a mysql database that is accessed through hibernate.
The autocomplete field is a struts tag called sj:autocompleter. The problem is that I am absolutely unable to get it to work! The field should show, as options, a set of strings extracted from the database. How do I launch an action when typing in the field to view the strings extracted from the db? The online examples only talk about json and I am not able to adapt them to my needs. What I have written so far is:
<%@ taglib prefix="sj" uri="/struts-jquery-tags"%> (this on the top of the jsp page) <sj:head jqueryui="true"/> (this in the head section) (this in the body section) <s:form action="Dashboard" theme="bootstrap" cssClass="form-horizontal" label="Form with jQuery UI Elements"> <s:url id="languages_url" action="Login"/> <sj:autocompleter id="autocompleter" parentTheme="bootstrap" label="Autocompleter" tooltip="Tooltip for Autocompleter" href="%{languages_url}" loadMinimumCount="1" /> </s:form>
At the moment, the Login action is only a "test action" so it does not return anything, but I don't receive any error message..absolutely nothing happens when I type in the field...no error, no message, nothing...simply, the action is not called.
How can I solve the problem? what should be the action implementation?

Thanks in advance!

P.S. I have correctly imported the struts2 jquery plugin.

no one can help me?
I don't know if the question is too complex, unclear or little detailed.

I am not well-versed in the jQuery plugin, but if you want to use AJAX to load the selections, I think you will have to use JSON. There is no way to return a Java object like a String array via HTTP without transforming it into plain text.
If you don't require AJAX, this example shows how to use the tag with a plain String array.
