in continuation of my previous problem.

I restarted tomcat and now the exception in other machines has changed:
Java Console shows:-

Any help or idea appreciated..!!

Thanks...

Hi ulf..
i mentioned it before that the applet is loading on the same machine.

as far as knew, the .class extension may/maynot be used in <applet code="">

anyways, i checked and changed code="HelloWorld" and the same error has occured. the applet is loading successfully on the same machine.. but not on other,, the message in java console is same as before with 1 change:

java.lang.ClassNotFoundException: HelloWorld

NOTE: May be some kind of security issue is there, if u see the console msg carefully it says: Caused by: java.io.IOException: Authentication failure

any idea wat does dat mean??

My aim is not to run this HelloWorld applet.. its actually a test applet i made juct to check whether simple applets are loading properly or not..

As for JDK. im using j2sdk1.4.2_08

Hi,
I am using Tomcat 4.1 as the server. i have a simple java applet HelloWorld.java . have kept the class file and html calling applet in proper loction. am using https.
Problem: the applet is accessible from the same machine(i.e. machine where tomcat is installed) url:https://<DNS>:8443/chat/index.html , where index.html has the applet tag. note: DNS is registered

but when i try to open the url from any other machine, the html page loads but NOT the applet. i cant reaaly find the problem..browser says:Applet not inited. neeed urgent help!!

Below is the message in Java Console:-
load: class HelloWorld.class not found.

java.lang.ClassNotFoundException: HelloWorld.class
