Error in accessing .jnlp file from a web link

I have a java application uploaded on a web portal linked to a .jnlp file. The link of the file is in a html file Launch.html shown as below:

enter image description here The error I am getting when I click on launch button is as follows:

HTTP Error 404.3 - Not Found
The page you are requesting cannot be served because of the extension configuration. If the page is a script, add a handler. If the file should be downloaded, add a MIME map.

launch.jnlp contents:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<jnlp codebase="" href="launch.jnlp" spec="1.0+">

    <title>BuisnessInternals</title>

</jnlp>

launch.html contents:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
    <title>Test page for launching the application via JNLP</title>
</head>
<body>
    <h3>Test page for launching the application via JNLP</h3>
    <script src="http://java.com/js/deployJava.js"></script>
    <script>
        deployJava.createWebStartLaunchButton("launch.jnlp")
    </script>
    <!-- Or use the following link element to launch with the application -->
    <!--
    <a href="launch.jnlp">Launch the application</a>
    -->
</body>
</html>

Any ideas how can solve it?

Specify MIME type in your JnlpDownloadServlet 

response.setContentType("application/x-java-jnlp-file");

Read this Java Web Start tutorial for clear understanding.

Edit

<a href="launch.jnlp">Launch the application</a>

The above html link you specified should work properly, make sure your launch.jnlp file path where you kept something like <a href="/somepath/launch.jnlp">

Seems like the web server needs some extra configuration to correlate the .jnlp file extension with the application/x-java-jnlp-file mime type.
