sfStart and program arguments

Hi all, hopefully someone here can help me. 

Is there a way to pass Java program arguments into the sfStart command?

I have deployed a description that loads a Java RMI server application.
And
for the the server application to work it needs to bind itself with an
RMI
registry and therefore needs to have a java security policy file
associated
with it passed in as an argument.

Also, does anyone have any information about how i can hard code a java
secuirty policy into a Java program?

Many thanks,
Gary
