Hi Davide,
You are right that the issue is because you instantiate SecurityFilter
as follows:
new SecurityFilter();
You need to first of all make the SecuredFilterFactory spring managed
and then either:
1) Inject the stuff onto SecuredFilterFactory and pass those injected
references to the constructor of SecurityFilter; or
2) Use the Spring API to programatically obtain a reference to
SecurityFilter. To do that you will need to inject something onto
SecuredFilterFactory to look up references, but i dunno what
that is.
Paul.
