Help: Access denied

I have created a "FtpClient Applet", which uses Jakarta FtpClient. When I load the applet the first time everything works fine. But if/when I get a timeout, have to change user, or for some other reason, have to reconnect to the ftp server I'll get the following Exception:

LoginToFtpServer() exc: access denied (java.net.SocketPermission XXX.com resolve).

I don抰 understand why I can access the server the first time but not the second time. If I press F5 (reload IE). I have of course signed my Jar files.

Can some one help me?
