Question

running this applet on some machines wont work but then on some other’s it works just fine. in all cases looks like JRE 1.6.0_26 has been installed.

<script type="text/javascript" src="http://www.java.com/js/deployJava.js"></script>
<script>
var attributes = {codebase:'http://kash-dev/applet/',
        code:'Auth.class',
    archive:'Auth.jar',
    id: 'auth',
    width:0, height:0} ;
    var version = '1.6' ;
deployJava.runApplet(attributes, null, version);
</script>

Here’s the error:

load: class Auth.class not found.
java.lang.ClassNotFoundException: Auth.class

It turns out that the network proxy setting in Java control panel was set to “user proxy server” even-though the settings for it’s address/port was identical to that set in the “browser settings” JVM was not able to resolve the JAR file URL correctly. Switching to “use browser setting” resolved the problem. Thank you all who responded.
