I need the original EJS source in order to find out what might be the problem.

Strange error message from PC where i am not admin
i suspect is a PC problem or firewall or bandwidth or 2 java applet loading at same time?? The applet definitely works on most PC.

I can not find the error when I run it.
Are you running it as an application? or with a browser?

Open the java console before you open it with the browser, and click "l" and "5" keys to change log mode.
Load applet into browser and find out the message shown.

not to worry, it is likely this pc problem.

i just found JAVA http://java.sun.com/javase/downloads/index.jsp
 
Java SE Runtime Environment (JRE)
JRE 6 Update 12
This release includes the highly anticipated 64-bit Java Plug-In (for 64-bit browsers only), Windows Server 2008 support, and performance improvements of Java and JavaFX applications.  Learn more   

Java SE Development Kit (JDK)
JDK 6 Update 12
This JDK includes the JRE and command-line development tools that are useful for developing applets and applications.  Learn more   


I installed both to be sure, and it works now!

It take a lot of time maybe 5 minutes or there about to load the applet on this PC. but it works so i am not complaining Grin
