Access denied Error Java.util.Propertypermission Lotus.domino.trace read

We have created a signed applet ,which initiates the notessession using NCSO.jar . We have signed the NCSO.jar using the same key as of the applet. while invoking the applet we get the error “Access denied Java.util.Propertypermission Lotus.domino.trace read”

We are not sure about the specific permission that we should grant in the policy file.

Is it possible to invoke the NSCO objects from Applet ? If so then kindly provide some guidance on the specific procedure for the same.

We appreciate your help in this regard.
