Hi,
I am using JAVA Version 1.6.38

I've had some reports that Java 1.6 is no longer working with the applet.

The only thing I can suggest for now is to downgrade jzebra and see if that 
helps, or update your Java to version 1.7.

In the mean time, I'll keep this bug open and try to set up an environment that 
matches yours to see why security exceptions are being thrown in Java 6.

@balkiindia87,

I have tested jzebra 1.4.9.1 with Java 1.6 u38 and I can confirm this DOES NOT 
work.

You should UPDATE JAVA TO 1.6 U45 or DOWNGRADE JZEBRA to version 1.4.7.

Warning, 1.4.7 WILL NOT WORK with Java 7 U21 or higher.

I'm not sure what is causing this compatibility.  I get a different message:
  > load: class jzebra.PrintApplet.class not found.
