Application Error: AccessControlException

问题

When I called JApplet class from JSP like this :

 <jsp:plugin 
      type="applet" 
      code="Class_Name.class" 
      codebase="classes"  
      width="850 height="850">
 </jsp:plugin>

I got an error:

access denied ("java.util.PropertyPermision" "com.sun.media.jai.disableMediaLib" "write")

What is the problem? and what can I do to fix it?
