signed applets

hi
i knwo an applet cannot acces files unless it is a trusted
apllet
.
i also know aplets have to be signed from somewhere to access files.
but fromm where???
i have also worked on an example from java.sun..com which writes a file on my hard disk when applet is downloaded.
but with that example only appletviewer can work ,
not the browser.
i suppose u have to pay to get signed applets .
but from where??
who to contact to get my applet signed .
pls help , urgent ..
thx
regards....

This is really a question more suited to the Applets forum, so I've moved it.
