Hi Everybody,
in p.no 680 of HFSJ i am surprised on the answers for the Request path 2 and 5.

can any body explain me how the URL matching happens here .Is it same as
Exact, Directory and Extension matching used by container for resource finding, if this is the case, then for the Request path 2 the answer should be 2, 1, 5.

Could any body clear my doubt.

Any help is appreciated.

<Filter mapping> can be done either using <url-pattern> or <servlet-
name>


Follow this process

All the filters with matching URL pattern are placed in the chain in
the order in which they are declared in DD.

Then all the filters with matching <servlet-name> are placed in the
chain in the order in which they are declared in DD.

Now for example
Recipes/HopsList.do has the matching

<url-pattern>/Recipes/*</url-pattern> ----------------1
<url-pattern>/*</url-pattern> ------------------------5
<servlet-name>/Recipes/HopsList.do</servlet-name> ----2

Here all filters with matching URL patterns are placed first and then
all filters with matching servlet-name

Regards
Gaurav
