in servlet Filter's method doFilter does not call

Question

i have to create a program to login on facebook using example

http://code.google.com/p/facebook-java-api/wiki/Examples

but when i run project then i get my doFilter method does not call after complete init method

Answer 1

The init() will be called on server's startup. The doFilter() will only be called when a HTTP request has been fired which matches the url-pattern of the Filter as definied in web.xml.

The easiest way to fire a HTTP request is using a webbrowser. For example Firefox. Enter the desired URL matching the Filter's url-pattern in the address bar.
