No Sign of Applet Running from HTML
Question
I put together a java ChatClient and ChatServer on Max OS X Version 10.7.5 for fun with my kids. We were using Java Version Java(TM) SE Runtime Environment (build 1.7.0_04-b21) . It runs great from the Terminal. Also, we'd like to able to run it from Eclipse by passing in parameters.
When I open the HTML in Safari 6.0.2., I get no sign of errors or the applet running. In Safari, I have enable plug-ins, Java, and Javascript. Only the text in the HTML is displayed; the applet does not seem to run or anything.
Once I get this working, I would like to package in a JAR file and sign it so I can create a socket to my server. The applet is a simple guy that asks to connect via socket, then sends and receives text from any other clients including itself.

In section 13.4, the APPLET tag in HTML is deprecated, and it's successor is the <object> element. You should think about a couple things here -
First, abide by HTML standards. This includes having all of your html tags and attributes in lowercase. <PascalCase> , <camelCase> are not standard for HTML.
Second, switch your applet tag to an object.
Thirdly, wrap all text in a block tag other than <body> . Most popular one is <p> meaning paragraph.
Fourthly, wrap ALL html attribute values in double quotes. example: width=200 should be width="200"
Fifthly, think about doing 2 spaced tabs when doing html. it's much cleaner :)
I could go on, but i could be here forever. Bottom line is, follow standards .
But to answer your question: In the specification, it looks like it expects the file name. this includes ".class" at the end. Try,
<html>
<head>
<title>Java Applet Example</title>
</head>
<body>
<div id="container">
<applet code="ChatClient.class" width="200" height="100">
<param name="host" value="xxxxx-iMac.local" />
<param name="port" value="4445" />
</applet>
</div>
</body>
</html>
