Hi,

<url-pattern>/*</url-pattern> is same in both conditions.

How will the server decide on which filter to use.

Subject: Intercepting Filter: Filter Chaining in Action

Hi Folks,

I have read Core J2EE Patterns. But I have a question concerning Filter API.

There is a example about Filter Chaining in Action. It uses a class that
implements a Filter and a servlet. The web configuration is

...

<filter-mapping>

<filter-name>StandardEncodeFilter</filter-name>

<url-pattern>/EncodeTestServlet</url-pattern>

</filter-mapping>

<filter-mapping>

<filter-name>MultipartEncodeFilter</filter-name>

<url-pattern>/EncodeTestServlet</url-pattern>

</filter-mapping>

But, I need to use two classes that implements a Filter. I?m trying to use this
configuration in my web.xml (Tomcat), but it doesn?t work. Could you help me,
please?

<filter-mapping>

<filter-name>StandardEncodeFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<filter-mapping>

<filter-name>MultipartEncodeFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

Thank you.
