Can servlet filter be applied to a method of a Java Bean

HI,
I am new here and I would like to implement the access control concern as a
filter.

There are serveral methods like read(...), insert(...), update(...),
delete(...) in a Java bean. I want the access control checking is performed
right before the execution of each of these methods.

The problems are:
1. Can a filter be applied to a method of a Java Bean?
2. Also I need to pass all the parameters of the method to the access
control checking. How to do this?
3. Sometimes a method will be called inside the other method like:
update(...)
{
  ...
  read( ... )
  ...
}
But I do not want the access control checking to be performed before this
read method which is nested in the update method. Is there a way to control
the flow?

Thanks in advance.

Lily
