Hi ranchers..

Confused about filter invocation sequence...
Following is from JFS/J (I didn't understand the rules)
Please explain...




From HFS/S (page 680)

Based on the following DD fragment, write down the sequence in which the filters will be executed for each request path. Assume Filter1 through Filter5 have been properly declared

<filter-mappling>
<filter-name>Filter1<filter-name>
<url-pattern>/Recipes/*</url-pattern>
</filter-mapping>

<filter-mappling>
<filter-name>Filter2<filter-name>
<url-pattern>/Recipes/HopsList.do</url-pattern>
</filter-mapping>

<filter-mappling>
<filter-name>Filter3<filter-name>
<url-pattern>/Recipes/Add/*</url-pattern>
</filter-mapping>

<filter-mappling>
<filter-name>Filter4<filter-name>
<url-pattern>/Recipes/Modify/ModRecipes.do</url-pattern>
</filter-mapping>

<filter-mappling>
<filter-name>Filter5<filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

Reques path: Sequence ?
/Recipes/HopsReport.do ??
/Recipes/HopsList.do ???
/Recipes/Modify/ModRecipes.do ???
/Recipes/Add/AddRecipes.do ???




Thanks much...

Thanks vishnu,

I got it right away...
I overlooked the <servlet-name> element in the second/fourth filter mapping !!!
Also, my post had some typos...

Makes perfect sense now...
