<h1>Embedding a Vaadin UI</h1>
<p>This is a static web page that contains an embedded Vaadin
application. It's here:</p>

<div style="width: 300px; border: 2px solid green;"
id="TestchangelistenerUI" class="v-app">

use an application built with Vaadin.</noscript>

and here is my web.xml

when I’m trying to load html I see this error
"XMLHttpRequest cannot load http://localhost:8088/testChangeListener

What am I doing wrong?
