Execute method each request
I want to execute a method each time a request is performed to my jsf site.
The implementation for this request should remain in a jar file which is
packed into the WAR file under WEB-INF/lib directory.
I guess there is no solution to do this with a valve, because the class
(jar) for the valve must remain inside tomcat classpath I guess.
Is there any other solution to invoke a method of a class inside the
WEB-INF/lib directory each request... Additionally the method must be
executed in the thread of the request.
I deploy the WAR into JBoss 4.0.5 with tomcat 5.5

Don't use a valve. Use a Filter. These were designed to be deployed as
part of your application, instead of being provided by Tomcat.
Look at the servlet API for javax.servlet.Filter (it's an interface).
Implementing it is easy: just read the javadoc before you begin and
you'll be good to go.

What you describe is exactly what filters were created for. It's even
in the servlet spec, making it a requirement of all java servlet containers.
