    <p>I'm trying to use jQuery UI autocomplete widget in my Java Webb App.</p> <p>As it is right now I have the following code:</p> <p><strong>View (buscarFoto.jsp)</strong></p> <pre><code>&lt;%@page contentType="text/html" pageEncoding="UTF-8"%&gt; &lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;link rel="stylesheet" type ="text/css" href="css/jquery-ui-1.10.3.custom.css"/&gt; &lt;script src="js/jquery-1.10.2.min.js"&gt;&lt;/script&gt; &lt;script src="js/jquery-ui-1.10.3.custom.js"&gt;&lt;/script&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=UTF-8"&gt; &lt;title&gt;JSP Page&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;h3&gt;Escull usuari&lt;/h3&gt; &lt;input type="text" id="usuari" name="usuari"/&gt; &lt;script&gt; $("#usuari").autocomplete({ source: "Controller?action=llistaUsuaris" }); &lt;/script&gt; &lt;/body&gt; </code></pre> <p></p> <p><strong>Controller (Controller.java (servlet))</strong> (DoPost and DoGet are overwritten, Controller.java works just fine as Servlet in any other part of the WebApp)</p> <pre><code> response.setContentType("text/html;charset=UTF-8"); PrintWriter out = response.getWriter(); try { GestioDB_Postgres db = new GestioDB_Postgres(); HttpSession session = request.getSession(); String op = request.getParameter("action"); if (op.equals("llistaUsuaris")) { String query = request.getParameter("term"); List&lt;String&gt; usuaris = db.llistaUsuaris(query); Iterator&lt;String&gt; iterator = usuaris.iterator(); while (iterator.hasNext()) { String usuari = (String) iterator.next(); out.println(usuari); } } </code></pre> <p>The call to the database in line 3 of the Controller works just fine (I've tested it), and the controller itself works fine too (it prints the appropriate "usuaris" when I run it in NetBeans), the .jsp page sends the request as "term", but the autocomplete function simply doesn't do anything.</p> <p>I read in another question that someone suggested using JSON but I'd rather not use it if it can be avoided. Can anyone point me in the right direction?</p> <p>Thank you.</p>

    3. COWell the I don't think that the servlet sending the results in the array format which is accepted by the `autocomplete`. You can chek the response in the `net` tab of your browser console for the foormat that the servlet is returning. It is returning `string` not the array. You have to split the string in array in javascript when you recieve the response, before using it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
