Filters : Filters are used to bypass some operaions when the applicaion is iniialized.
Some custom ilters are added to make the applicaion behave in a way the user
wants. <filter-name> and <filter-class> are used to define the filters. The
<filter-mapping> elements are used to map the filter name with the servlet and
the paterns required to ilter the URL are added. The <dispatcher> element will
make sure that the URL is forwarded to a proper low in the applicaion.
Listeners : Listeners are added to an applicaion to listen and execute based on some
acion performed in the applicaion life cycle.
Servlets : These are the controller elements for the web applicaion that will forward
and request the page for the user. The <servlet-name > and <servlet-class>
elements are enclosed in the <servlet> element to deine the servlet informaion.
The <servlet-mapping> element will deine the URL patern that has to be
applied to process the page using the specific servlet class.
