    <p>I'm having some problem with Json. I want to send a json object to a database on a server and in return get a json result. I'm working with KnockoutJS, jQuery and struts-2.</p> <p>This is javascript code:</p> <pre><code>function(ko, dataservice, config, router, messenger, Utente, Vario) { var logger = config.logger, utente = new Utente(), vario = new Vario(), isValid = ko.computed(function() { return utente.username() &amp;&amp; utente.password() &amp;&amp; utente.email(); }), activate = function(routeData, callback) { }, registrazione = function() { if (isValid()) { if (utente.password() === vario.password()) { dataservice.servizisegreteria.registrazione({ success: function(result) { if (result.esito === 'OK') { router.navigateTo(config.hashes.registrazione); logger.info("Controlla la tua casella mail!"); } else { logger.error("Salvataggio non riuscito!"); } }, error: function(result) { logger.error("Controllare che i dati siano giusti!"); } }, $.toJSON({ 'utente': { 'username': utente.username(), 'password': utente.password(), 'email': utente.email(), 'dataIscrizione': new Date() } })); } else logger.error("Le Password devono combaciare!"); } else logger.error("Inserire tutti i dati!"); }; return { activate: activate, utente: utente, vario: vario, registrazione: registrazione }; } </code></pre> <p>This is code for ajax request:</p> <pre><code>var init = function() { amplify.request.define('registrazione', 'ajax', { url: '/VenditaGioielli/gestioneSegreteria/nuovoUtente.action', dataType: 'json', type: 'POST', contentType: 'application/json; charset=utf-8' }); }, registrazione = function(callback, data) { return amplify.request({ resourceId: 'registrazione', data: data, success: callback.success, error: callback.error }); }, init(); return { registrazione: registrazione } } </code></pre> <p>This is html code:</p> <pre><code>&lt;%@page contentType="text/html" pageEncoding="UTF-8"%&gt; &lt;%@taglib prefix="s" uri="/struts-tags" %&gt; &lt;script type="text/javascript"&gt; &lt;/script&gt; &lt;section id="registrazione-view" class="view"&gt; &lt;div id="container"&gt; &lt;div id="contenuto"&gt; &lt;div class="formGioiello"&gt; &lt;div class="gruppoInput"&gt; &lt;div&gt; &lt;label&gt;Username&lt;/label&gt; &lt;input type="text" placeholder="Username" data-bind="value: utente.username" required/&gt; &lt;/div&gt; &lt;div&gt; &lt;label&gt;Password&lt;/label&gt; &lt;input type="password" placeholder="Password" data-bind=" value : utente.password" required/&gt; &lt;/div&gt; &lt;div&gt; &lt;label&gt;Ripeti Password&lt;/label&gt; &lt;input type="password" placeholder="Ripeti Password" data-bind="value :vario.password" required/&gt; &lt;/div&gt; &lt;div&gt; &lt;label&gt;Email&lt;/label&gt; &lt;input type="email" placeholder="Email" data-bind="value :utente.email" required/&gt; &lt;/div&gt; &lt;/div&gt; &lt;div&gt; &lt;button data-bind="click: registrazione, jqueryui: 'button'"&gt;Registrati!&lt;/button&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; </code></pre> <p></p> <p>this is struts.xml</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8" ?&gt;

} public String getIdUtente() { return idUtente; } public void setIdUtente(String idUtente) { this.idUtente = idUtente; } } </code></pre> <p>I'm getting this error while getting data from database: </p> <blockquote> <p>JSON.parse: unexpected character error</p> </blockquote> <p>in fact, netbeans doesn't even get to the <code>GestioneUtenteAction</code> class on debug mode! </p> <p>The json object sent is</p> <pre><code>{"utente":{"username":"luca","password":"l","email":"ho@ho.it","dataIscrizione":"2013-11-04T13:30:09.575Z"}} </code></pre> <p>Does anyone have a clue how to fix this?</p> <p>EDIT: the action isn't hit, and the answer from the server is my html page, instead of a json object. This html is given to the parseJSON function of jquery. I came to this result by comparison whit another working action</p>

    1. COIf you're getting a JSON parsing error, the first thing to do is look at the JSON being returned (in the Network tab of your browser's dev tools) and make sure it's valid. And if it is, post the valid JSON to the question.

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).
