Filters are covered in the "More Servlets" book, which is the next edition of the "Core Servlets" book.
-----Original Message----- From: Price, Erik [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 11, 2002 9:06 AM To: [EMAIL PROTECTED] Subject: learning filters I have been learning about servlet programming from "Core Servlets". I like this book. But, since subscribing to this list, I have seen mention of "filters". In a message from Yoav Shapira I was recommended to use "filters" to validate form data before passing it to a servlet. This seems to me a cleaner means of doing it, as opposed to putting form-validation code in the servlet. However, "Core Servlets" does not describe how to use filters (that I know of). Is there a reference for this technique somewhere, or is it a generic term for "a servlet that intercepts, acts upon, and passes along data" ? If it is the latter then I can figure it out from using getDispatcher().forward() etc but if it is a specific technique then where can I learn more? My Tomcat container is v. 4.0.6.
