Answer Posted / surajkumar.java
A java class which implements javax.servlet.Filter is
configured as filter in web.xml file.
The web container calls the init method to initialize filter
by passing javax.servlet.FilterConfig object to retrieve the
filter’s init parameters.
The doFilter method of Filter class performs the actual
processing like authentication, data format conversion and
page redirect to other page and catching etc. The doFilter
method passes the request and response object of the current
request and the filter chain object to invoke next filter in
the chain.
Web container calls the destroy() method to take the filter
out of service.
