Can you tell where that error is coming from? I don't recognize it as
an APT error, so I'm guessing Struts, but I don't recall ever seeing
that before.
You know what... what happens if you remove the <?xml> and <!DOCTYPE>
tags? Does it work then?

ok, the Text in the index-result is working now, but i want to use the
actions and when i use parameters like
"/employee.do?task=update&ajax=getEmployee" then there comes an error
message "The reference to entity "ajax" must end with the ';' delimiter."

Hello,
now i am using the javawebparts.ajaxparts and when i put all the things
in a whole jsp-site, than the ajax is working:
<%@ taglib prefix="ajax" uri="javawebparts/ajaxparts/taglib" %>
<?xml version="1.0" encoding="ISO-8859-1" ?>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
<title>Insert title here</title>
</head>
<body>
<form action="#">
<input id="btn" type="button" value="TESTBUTTON"/><ajax:event
ajaxRef="employee/update" attachTo="btn"/>
</form>
<div id="result-div">
</div>
<ajax:enable/>
</body>
</html>
But when i am using it with struts-tiles than it doesn't work :-( - i
think that's because the target in the ajax-config is not found. I don't
now why. Without tiles, the target
will be found. The index-result.txt is in the same directory as the
jsp-site.
<ajaxConfig>
<group ajaxRef="employee">
<element ajaxRef="update">
<event type="onclick">
<requestHandler type="std:SimpleRequest"
target="index-result.txt">
<parameter />
</requestHandler>
<responseHandler type="std:InnerHTML">
<parameter>result-div</parameter>
</responseHandler>
</event>
</element>
</group>
</ajaxConfig>
When i use an action as a target, it doesn't work, too (e.g.
target="action.do?parameter=xxx¶m2=yyy). I use the DispatchAction,
so with the parameter I can delegate or specifiy the method, which will
be called in my action...
Any ideas?
Thank's a lot!!
Greetings from Berlin

I should also point out the presentation Ted Husted did at The Ajax
Experience last week which dealt largely with APT. The slides for that
presentation are here:

I'm not quite sure how long they will stay posted there though, so get it
while it's hot :)

There's a couple if ways you could do that... one would be to call the
submit() method of the form object, which every form in HTML has, then
re-render the page with the updated data in the form. That's of course
going to refresh the entire page, which I suspect isn't what you want.
So, AJAX is probably what you want. Now, how you go about doing that,
well, there's a few hundred options :) Because you don't know a lot of
Javascript, you might want to consider the AjaxParts Taglib (APT) from
Java Web Parts (JWP):
http://javawebparts.sourceforge.net
Direct to APT:
http://javawebparts.sourceforge.net/javadocs/javawebparts/ajaxparts/taglib/package-summary.html
If you go to the download page, the cookbook has some examples that are
very much along the lines of what you're asking for. If you go that
route, we'll be more than happy on the JWP mailing list, or forums.
Otherwise, prototype (http://www.prototypejs.org) is a good, simple
option, but you will be writing some Javascript.
