No it's not mandatory to have a servlet in order to use a filter.
Say we have a filter:
This will filter ALL requests received, irrespective of the resource requested. Images, pages, stylesheets, the works.
I'm not entirely sure what you ment by calling a servlet using a filter, but I suspect you either want to redirect to the servlet url, or request a servlet resource while processing a user request.
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws
2) Requesting a servlet:
url = new
myStream = url.openStream();
//Code to read
' response from the myStream
We're doomed!!<br />Yay!!!<br />No that's bad Girr!!<br />Yay!!!
I agree. Here's the link:
