AJAX div loads local URL but not remote one
Hi all,
I'm trying to learn how to use AJAX, but I'm having some trouble. In the
JSP below, the first <s:div/> loads the URL just fine, but the second
<s:div/> simply displays "Loading..." and stays that way forever. IE
displays "Error on page" in the status bar when it is (apparently) trying to
contact the server, then "Done". Is there anything that needs to be done
differently for a remote URL?
Thanks.

This is not specific to the Struts ajax tags, HXR (ajax) calls can only be
done to the domain from where the page was loaded from. Dojo and other
frameworks use some neat tricks to get around this, but the Struts ajax tags
do not expose this Dojo functionality yet.

Thanks. Does that mean that the ajax tags allow only clients in the same
domain as the server to communicate with the server? Or does it mean that
clients (in any domain) can communicate only with the server that served out
the pages containing the ajax call?

Dojo supports crossdomain XHR using IFrames, but the ajax tags do not
support it, yet.

Sorry about that... cut and paste went crazy on me; let me try again. Here
is the JSP again:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Welcome</title>
<s:head theme="ajax"/>
</head>
<body>
<hr/>
<s:div theme="ajax" id="search" href="
http://localhost:8080/Struts2-tutorial1/">
Local page goes here.
</s:div>
<hr/>
<s:div theme="ajax" id="live365" href="http://www.google.com"
loadingText="Please wait . . ." errorText="Sorry, can't load remote page">
Remote page goes here.
