After long and frustrating retries to build working servlet front controller that will answer any user request , I managed to build filter servlet using tomcat's filter mapping
Its working great!
I am able to catch every user request!
My problem is that I am unable to communicate with user applets using streams , Example Filter:

Anyone used this kind of communication?
Please feel free and post anything that can assist me .(links , examples ,etc)
Thank you all !

hi Cindy
I downloaded the 17 chapter pdf and read it,
I am able to communicate between applet and normal servlet using GET POST and byte streams,
My problem start when I am using j2ee Intercepting Filter pattern can be found here:
http://java.sun.com/blueprints/corej2eepatterns/Patterns/InterceptingFilter.html
I am unable to stream data between the applet and my filter servlet,
This filter extending the Filter class instead of the: HttpStrvlet class
And receiving ServletRequest and ServletResponse as parameters instead of:
HttpServletRequest and HttpServletResponse in normal servlet.

Thank you ,
Sharon.
