The tapestry5-acegi library adds a few request filters that run
between your browser and the T5 engine. It also adds a few hooks to
your classes defined by the @Secured annotation. These hooks are
executed before your class by a few Acegi classes which checks right
permissions/roles, etc and either gives you access to the page or
redirects you to the defined login page.
Depending on your needs, Acegi might be the bigger hammer to punch the
little nail :-).
To ask your second question, the code tapestry5-acegi uses to wrap
around the class is found here in this service:
<http://www.localhost.nu/svn/public/tapestry5-acegi/trunk/src/main/java/nu/localhost/tapestry/acegi/services/internal/AcegiWorker.java>
