Hi, sorry but my computer is a confusion because i had some problems when
developing my application and i had to get an older version.
That error does not appear anymore, however i have a new exception. Do you
have an ideia about this?
The application continues to run perfectly in localhost and the adress that
i use to run the applet is http://phc:8000/aplicServ where aplicServ is a
servlet wich dispays the applet. This applet will then try to communicate
with other servlets like http://phc:8000/main for example, all servlets are
running in this server.... And i acess this servlet's through the browser
with this adresses...
This only occurs when i run my application from another machine, in
localhost it communicates perfectly
Exception occurred during event dispatching:
java.security.AccessControlException: access denied

And my java.policy file looks like this:

};
Thanks for your help.

Subject: Re: java.net.ConnectException in applet connection to servlet
Hugo,
This error seems to indicate that your web server is not listening on port
8000. What is the url that you use in your browser to retrieve the page
that contains the applet?
