java.lang.SecurityException: sealing violation:

Asked 2012-04-10T17:06:44.710

I am using GWT for my Java application. When I try to run it as web application, I get the following error:

java.lang.SecurityException: sealing violation: can't seal package org.mortbay.util: already loaded

I can't find anything helpful if I Google for the error. Am I missing something?

java gwt

It means the package is sealed and you tried to load another jar also containing the package.
