I been shopping in the pet store and I'm confused about how the FilterChain gets setup.
The following element is from the 2.3 DTD.
<!ELEMENT filter-mapping (filter-name, (url-pattern | servlet-name))>
So if I have the following in my deployment descriptor:
<filter-mapping>
<filter-name> filter_1 </filter-name>
<servlet-name> myServlet </servlet-name>
</filter-mapping>
<filter-mapping>
<filter-name> filter_2 </filter-name>
<servlet-name> myServlet </servlet-name>
</filter-mapping>
<filter-mapping>
<filter-name> filter_3 </filter-name>
<servlet-name> myServlet </servlet-name>
</filter-mapping>
I can expect the container to setup the FilterChain of filter_1, filter_2, filter_3.
The FilterChain.doFilter( req, res ) is a call from filter to filter?

Hi Bob,
Your assumption is correct: the container will setup the filter chaining for you.
However, you will need to indicate (in your filter code) when this chaining occurs. This is where you will have to call the chain.doFilter (request, response) method.
Cheers
