I need to intercept requests processing by the Webserver and I need to add my own filter that is based on some conditions.

Can I do this in java for any of the java or non java webservers or application servers.

Looking for the replies.

You already partially answered your own question: use a ServletFilter: Make a class that implements javax.servlet.Filter. Set it in your web.xml. And that's it.... Use Google for ServletFilter

public class MyServletFilter implements Filter {

public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain) throws IOException, ServletException {
//cast request to HttpServletRequest and have fun!!
//and forward the req/resp to the next one, or to the server when done
filterChain.doFilter(request, response);

In your web.xml:
