No response in autocomplete with remote source (JSP)

No response in autocomplete with remote source (JSP)

Hi,

I'm completely new to jQuery, though I have some basic Javascript skill. I'm trying to use the autocomplete widget. It works fine with local data on the page, but I can't make the remote version (reading from database) work. The letters I type in the autocomplete textbox are forwarded properly to my backend JSP/Java code, but the list that I create there is never showed in the browser.

Here are the two relevant snippets from my web page:
<script>
$(function() {
    $("#jquery_from_ob").autocomplete({
        source: "getblocks.jsp",
        minLength: 2,
    });
});
</script>

...

<div>
<input id="jquery_from_ob" name="jquery_from_ob" size="20">
</div>

In the getblocks.jsp page, I find the request parameter "term" and generate suggestions accordingly. But they aren't displayed on the web page. I've tried outputting normal strings and JSON-formatted data. A simple attempt might look like this:

<%
    for (String block : blocks) {
        out.println(block);   
    }
%>

I would be grateful for any suggestions.
