i have also tried this out for you. i wrote 1 basic servlet that acquired the 
session and added a String attribute, 1 basic filter that attempted to acquire 
that attribute from the session, and 1 jsp that was forwarded to using a 
RequestDispatcher from the basic servlet after the session attribute was added. 
this was configured in web.xml with a filter-mapping using a url-pattern for 
the location of the jsp, i.e /tests/33058.jsp. the jsp also tries to output the 
session attribute.

test 1 revealed that the filter is not even touched when the basic servlet is 
requested. the jsp is arrived at however, and does output the correct session 
attribute.

i consulted the servlet 2.4 specification and found that in 2.4 you add an 
element called "dispatcher" to the filter-mapping so that RequestDispatchers 
work with the url-pattern (section 6.2.5)

i change the filter-mapping to 

<filter-mapping>
  <filter-name>Basic Filter</filter-name>
  <url-pattern>/views/test/*</url-pattern>
  <dispatcher>FORWARD</dispatcher>
</filter-mapping>

running this test reveals that the filter _can_ access the session value:

String myAttribute = (String) ((HttpServletRequest) request).
  getSession().getAttribute("myAttribute");

hope this helps.
