Good day.
I installed the 'Java EE' bundle from NetBeans.com, thus with JEE
(jdk1.7.0_25 ), NetBeans IDE 8.0 and Apache-Tomcat 8.0.3 . I installed
also an authentication etc application : 'eid-applet-sdk-1.1.3.zip'.
In my new client-server application, opened as a web-application in
NetBeans and declared as using the integrated Tomcat server, a script
tag in the index.html page has to load from the server, to
automatically deploy and to run a Java applet (of class
'be.fedict.eid.applet.Applet.class' in the
'eid-applet-package-1.1.3.jar' file).
[code]<%@page contentType="text/html" pageEncoding="UTF-8"%>
<html>
    <head>
	<meta http-equiv="Content-Type" content="text/html;
charset=UTF-8">
	<title>Page JSP</title>
    </head>
    <body>
	<h1>Formulaire d introduction</h1>
	<script src="https://www.java.com/js/deployJava.js"></script>
	<script>
	    var attributes = {
		code : 'be.fedict.eid.applet.Applet.class',
		archive : 'eid-applet-package-1.1.3.jar',
		width : 400,
		height : 300
	    }
	    var parameters = {
		TargetPage : 'identity-result.jsp',
		AppletService : 'applet-servcice',
		BackgroundColor : '#ffffff',
		Language: 'fr'
	    }
	    var version = '1.1.3';
	    deployJava.runApplet(attributes, parameters, version);
	</script>
    </body>
</html>[/code](This code is the one serving as short example in the
developer's guide of the 'eID Applet' solution, one part of the 'eID
Fedict' government project) 
I downloaded for this purpose a 'eid-applet-package-1.1.3.jar' file and
installed it in a folder on my computer
(D:/DwnldApp/eid-applet-sdk-1.1.3), for application development
purpose. I expect to deploy it, later on, on the server
(Apache-Tomcat-Jasper), with the other developed files.
At run-time, the browser receives an html page containing a rectangle
(whose dimension as in the script parameters), as well as an originator
certificate, but doesn't receive the authentication applet.
Nevertheless, under [Web appl name] > Libraries in the 'Projects' tab
in NetBeans, 'eid-applet-package-1.1.3.jar' appears correctly, with the
rigth path and with [I]'be.fedict.eid.applet.Applet.class'[/I] as in
[I]var attributes = { code:[/I] in the script.
My question : How to make sure that Tomcat receives the correct path to
the applet class ? What else could go wrong ?
Thanks in advance.
P.S.: I'm using 
- System: Microsoft Windows 7 Professional edition
- Java: jdk1.7.0_25 and jre7
- NetBeans IDE 8.0
- Apache Tomcat 8.0.3
