SendMail Bean access error.

Question

I'm trying to use SendMail (Degrelle version) in my form.
All seems to be ok until I try to send the mail : I get a java.security.AccessControlException.
I'm using java plugin and I run OC4J server on the same system in which I use the browser.
I tried to find where and how java.policy should be set but I wasn't able to find a solution.
I added
grant {
     permission java.security.AllPermission;
to every java.policy file I found (more or less) but i get no result.
How can I solve that issue ?
