Filters chaining order

[Victor Dolirio]

Hi everyone,

I�m studing the HFSJ�s Filter Chapter and I�ve got a trouble in that exercise:

  Write down the sequence in wich the filters will be executed for each request path.
 
<filter-mapping>
  <filter-name>F1</filter-name>
  <url-pattern>/Recipes/*</url-pattern>
</filter-mapping>
 
<filter-mapping>
  <filter-name>F2</filter-name>
  <url-pattern>/Recipes/HopsList.do</url-pattern>
</filter-mapping>
 
<filter-mapping>
  <filter-name>F3</filter-name>
  <url-pattern>/Recipes/Add/*</url-pattern>
</filter-mapping>
 
<filter-mapping>
  <filter-name>F4</filter-name>
  <url-pattern>/Recipes/Modify/ModRecipes.do</url-pattern>
</filter-mapping>
 
<filter-mapping>
  <filter-name>F5</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

The answer says:
/Recipes/HopsList.do - Filter Sequence: F1, F5, F2
/Recipes/Add/AddRecipes - Filter Sequence: F1, F3, F5

It�s not right to me because I read in the book the filters chain is defined by finding all matches URL patterns and its order is the same defined in the DD. I figured out that its not defined by precedence order of the URL patterns because the first answer I listed would be F2, F5, F1. I�m fooled with this question! What is the right rules for Filters order??!
Can someone help me with my doubt?

Thanks all.

Even i got confused with this in my first reading of HFJS.
Carefully look at the tags in the book...

It is not
<url-pattern>/Recipes/HopsList.do</url-pattern>
however it is
<servlet-name>/Recipes/HopsList.do</servlet-name>

In case of filters, container decides the squence based on "US" (URL-Servlet) Hence the sequnce given in the book is correct.

Cheers...
