<servlet-name> inside <filter-mapping> of web.xml, what does this mean?
30,159
Have you tried Google ?
Why is it a servlet being mapped inside a tag? What does this kind of mapping imply?

what does
<listener>
do?

I am starting to learn Struts 2. I stumbled upon this code:
web.xml
...some other codes... <filter> <filter-name>MyFilter</filter-name> <display-name>MyFilter</display-name> <filter-class>com.xxx.yyy.zzz.MyFilter</filter-class> </filter> <filter-mapping> <filter-name>MyFilter</filter-name> <servlet-name>MyAction</servlet-name> </filter-mapping> <listener> <listener-class>com.xxx.yyy.StrutsListener</listener-class> </listener> <servlet> <servlet-name>MyAction</servlet-name> <servlet-class>org.apache.struts.action.ActionServlet</servlet-class> <init-param> <param-name>paramName1param-name> <param-value>paramVal1</param-value> </init-param> <init-param> <param-name>paramName2</param-name> <param-value>paramVal2</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> ...some other codes...
My question is in this part
<filter-mapping> <filter-name>MyFilter</filter-name> <servlet-name>MyAction</servlet-name> </filter-mapping>
Why is it a servlet being mapped inside a<filter-mapping>
tag? What does this kind of mapping imply? Also, what does<listener>
do? Thanks for the replies.
