    <p>I can't seem to get websocket communication to work in the Play Framework version 2.1. </p> <p>I created a simple test that does nothing but send messages back and forth with a push of a button. All the code for it is below. But nothing shows up except for the button.</p> <p>Has anybody seen this problem or can someone tell me what I may be doing wrong in the code below?</p> <p>I am using the latest version of Chrome.</p> <p>Here is my simple setup.</p> <p><strong>In Application.java</strong></p> <pre><code>public static Result index() { return ok(index.render()); } public static WebSocket&lt;String&gt; sockHandler() { return new WebSocket&lt;String&gt;() { // called when the websocket is established public void onReady(WebSocket.In&lt;String&gt; in, WebSocket.Out&lt;String&gt; out) { // register a callback for processing instream events in.onMessage(new Callback&lt;String&gt;() { public void invoke(String event) { System.out.println(event); } }); // write out a greeting out.write("I'm contacting you regarding your recent websocket."); } }; } </code></pre> <p><strong>In Routes File</strong> GET / controllers.Application.index()</p> <pre><code># Map static resources from the /public folder to the /assets URL path GET /assets/*file controllers.Assets.at(path="/public", file) GET /greeter controllers.Application.sockHandler() </code></pre> <p><strong>In Index.Scala.html</strong></p> <pre><code>@main(null) { &lt;div class="greeting"&gt;&lt;/div&gt; &lt;button class="send"&gt;Send&lt;/button&gt; &lt;script type="text/javascript" charset="utf-8"&gt; $(function() { var WS = window['MozWebSocket'] ? MozWebSocket : WebSocket var sock = new WS("@routes.Application.sockHandler()") sock.onmessage = function(event) { $('.greeting').append(event.data) } $('button.send').click(function() { sock.send("I'm sending a message now.") }); }) &lt;/script&gt; </code></pre> <p>}</p> <p><strong>In Main.scala.html</strong></p> <pre><code>@(title: String)(content: Html) &lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;@title&lt;/title&gt; &lt;link rel="stylesheet" media="screen" href="@routes.Assets.at("stylesheets/main.css")"&gt; &lt;link rel="shortcut icon" type="image/png" href="@routes.Assets.at("images/favicon.png")"&gt; &lt;script src="@routes.Assets.at("javascripts/jquery-1.7.1.min.js")" type="text/javascript"&gt;&lt;/script&gt; &lt;/head&gt; &lt;body&gt; @content &lt;/body&gt; </code></pre> <p></p>

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.

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