Glassfish 4 with JK-Connector to IIS Problem

Hi guys,

I have an issue with the following environment:
Glassfish open source 4.0
IIS of Windows 2008
Vaadin 7.2.7

If I open the application with the HTTP-Listener of Glassfish all works fine.
If I open the application via IIS and JK-Connector I get only the following html-fragment:

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta http-equiv="X-UA-Compatible" content="IE=11;chrome=1" />
<style type="text/css">html, body {height:100%;margin:0;}</style>
<link rel="shortcut icon" type="image/vnd.microsoft.icon" href="./VAADIN/themes/mytheme/favicon.ico" />
<link rel="icon" type="image/vnd.microsoft.icon" href="./VAADIN/themes/mytheme/favicon.ico" />
</head>
<body scroll="auto" class=" v-generated-body">
<div id="hdsc-3198028" class=" v-app mytheme">
<div class=" v-app-loading"></div>

You have to enable javascript in your browser to use an application built with Vaadin.

</div>
<iframe tabindex="-1" id="__gwt_historyFrame" style="position:absolute;width:0;height:0;border:0;overflow:hidden" src="javascript:false"></iframe>
<script type="text/javascript" src="./VAADIN/vaadinBootstrap.js"></script>
<script type="text/javascript">//<![CDATA[
if (!window.vaadin) alert("Failed to load the bootstrap javascript: .\/VAADIN\/vaadinBootstrap.js");
if (typeof window.__gwtStatsEvent != 'function') {
vaadin.gwtStatsEvents = ;
window.__gwtStatsEvent = function(event) {vaadin.gwtStatsEvents.push(event); return true;};
}
vaadin.initApplication("hdsc-3198028",{
"heartbeatInterval": 300,
"versionInfo": {
"vaadinVersion": "7.2.7"
},
"vaadinDir": ".\/VAADIN\/",
"authErrMsg": {

},
"widgetset": "de.la2.hdsc.ui.AppWidgetSet",
"theme": "mytheme",
"debug": true,
"comErrMsg": {

"serviceUrl": ".",

"message": "Take note of any unsaved data, and <u>click here<\/u> or press ESC key to continue.",

}
});
//]]></script>
</body>
</html>

Does anyone has an idean whats going wrong there?

There is nothing in the log which could explain that problem.

We have already installed a VVadin-application on Glasssfish 3.1.2.2 with IIS and JK-Connector and that works fine. As well the above installation of JK-Connector runs well with the same IIS and a different Glassfish (3.1.2.2).

In my eyes strange is the fact, that the application is delivered only partly without the effective body of the application.

Oliver
